Six interdisciplinary Duke faculty teams have received 2018-2019 Research Incubator Awards from the Duke Institute for Brain Sciences (DIBS). The awards provide seed funding to support collaborative brain science research for projects of exceptional innovation and broad significance to the field.

The projects must engage at least two faculty representing multiple fields or levels of analysis and bring together investigators from across Duke whose individual programs of research are not already connected.

“These outstanding teams will investigate a wide range of topics in innovative and collaborative ways,” said Geraldine Dawson, Ph.D., Chair of the DIBS Faculty Governance Committee and Director of the Duke Center for Autism and Brain Development. “We are excited to see the results of this research and the new collaborations that will emerge from it.”

The teams represent 11 departments in three schools: Biostatistics & Bioinformatics, Molecular Genetics & Microbiology, Neurobiology, Ophthalmology, Pediatrics, Pharmacology & Cancer Biology, and Psychiatry & Behavioral Sciences, from the School of Medicine; Biomedical Engineering, Mechanical Engineering & Materials Science, and Electrical & Computer Engineering, from the Pratt School of Engineering; and Psychology & Neuroscience from Trinity College of Arts & Sciences.

This year’s research topics include the sense of smell and copper metabolism, sleep rhythms and their relationship to health, neuron specialization, brain states as assessed by real-time analysis of neural activity, and early language development in the visually impaired. Each team will receive $100,000.

External Advisory Board Honors Memory of Julie Rhodes with Sixth Award

For the second year, the DIBS External Advisory Board members voted to fund an award in addition to the five supported by DIBS funding. This year’s sixth award honors the memory of Julie Rhodes, the first DIBS Director of Communications. A talented graphic designer and communicator, Rhodes was instrumental in the planning and opening of the new DIBS “Cube” and underground space. She died on August 17, 2018.

The project led by investigators Mike Tadross, Biomedical Engineering and Neurobiology, and Kafui Dzirasa, Psychiatry & Behavioral Sciences, was selected by the board. This project will examine the mechanism by which ketamine alleviates depression, in an effort to identify new therapeutic approaches. “We are very grateful to the Board members for their contributions to this valuable program, and for honoring Julie Rhodes, who was an extraordinary contributor to the success of the Institute,” said Nicole Schramm-Sapyta, Ph.D., DIBS Chief Operating Officer, who worked closely with Rhodes.

Earlier this year, DIBS announced recipients of its inaugural Research Germinator Awards, designed to support smaller, targeted requests for training, pilot data, salary, and/or equipment that would facilitate new research and lead to new external funding. Projects are awarded up to a maximum of $25,000 (nonrenewable). These awards are open to Duke graduate students, postdoctoral fellows, and faculty, and may be applied for by a single person or a team. See the Germinator teams and projects.

“One of our strategic priorities is catalyzing collaborative research,” Dawson said. “These awards programs help support the kind of high-risk, high-reward projects that make Duke and DIBS leaders in neuroscience.”

Following is more information on the six 2018-2019 Research Incubator Awards teams and projects.

Smelling Sulfur in Wilson’s Disease: How Does Copper Metabolism Affect Olfaction?

Wilson’s disease is a genetic disease caused by mutations in the copper transporter gene ATP7A, resulting in toxic accumulation of copper in various organs. This progressive accumulation eventually leads to liver and kidney damage and various neurological problems, among other complications. One curious attribute of patients with Wilson’s disease: they seem to be indifferent to sulfur-containing odors such as skunk spray, flatulence, and natural gas additive, which have a strong, disagreeable odor to most people. This suggests an unexpected link between copper metabolism and olfaction. We assembled a strong interdisciplinary team with complementary expertise in odor-receptor interactions (Matsunami) and odor-mediated behavior and odor coding in the brain (Franks), and copper transporters and copper metabolism (Thiele) to study this copper-dependent olfactory defect. We will test the hypothesis that copper-olfactory receptor-odorant interactions in the nasal mucosa are essential for sensitive detection and signaling of sulfur-containing odors, and copper maldistribution caused by Wilson’s disease compromises olfactory sensory neuron responses and specific odorant detection. Our project will validate a novel mechanism underlying the fundamental biology of smell and, importantly, could lead to an innovative olfactory-based method to screen non-invasively Wilson’s disease patients, enabling early interventions to reduce irreversible brain damage.

Deconstructing the Glutamatergic Basis of Depression

Major depressive disorder is the leading cause of disability in the world. Pharmacological treatments available fail to adequately treat the disorder in up to 50 percent of patients. Recent evidence indicates that ketamine, a drug with anesthetic and pain-killing properties, can effectively treat symptoms in this population. However, ketamine has many side effects that limit its broad clinical utility. In this study, we will use two groundbreaking technologies to uncover the mechanisms underlying ketamine’s antidepressant effects. The first technology, Drugs Acutely Restricted by Tethering (DART), offers the unprecedented opportunity to deliver drugs to genetically defined cell types in the brain. The second technology, Whole-Brain Electome Mapping (WBEM), allows characterization of whole-brain dynamics in animal models of depression, offering the opportunity to observe mood-related brain states with a sensitivity and specificity surpassing all known behavioral correlates of disease. Successful completion of this work will yield a multi-scale understanding of depression, providing insight into how a precise pharmacological intervention, targeted to specific cells in the brain, propagates to affect whole-brain dynamics and behavior. The work has the potential to yield a new class of precision therapeutics to rapidly reverse depressive symptoms in a broad patient population. (Note: This project was selected by the DIBS External Advisory Board to honor the memory of Julie Rhodes, the first DIBS Communications Director, who died in August 2018.)

Quantitative Investigation of the Specialization of Mechanotransduction Neurons

The sense of touch is crucial for our survival, and its malfunction is associated with inflammatory pain and chronic pain, for which medical treatments are still disappointingly inadequate. For this project, we will investigate how specific nerve cells are specialized to sense mechanical touch. Ample experimental evidence already suggests such a specialization. For example, some nerve cells only detect light mechanical indentation, whereas others respond exclusively to deeper indentation. We suspect that many additional types of specialization exist. However, a fundamental investigation and classification of nerve cells has never been performed, in part because this has not been technically possible. We will overcome this limitation by engineering a unique instrument that can measure precisely the electrical activity of nerve cells in response to a clearly defined mechanical stimulus. Next, we plan to use this instrument to measure and characterize hundreds of nerve cells, which will enable us for the first time to reveal exactly how they are specialized to sense mechanical touch. This knowledge would enable us to study the genes and molecules that determine the specialization of nerve cells for sensing mechanical touch and understand how the electrical response of neurons is changed in disease conditions, such as inflammatory pain.

Harnessing Sleep/Circadian Rhythm Data as a Biomarker to Mitigate Health Risks

Sleep is essential to sustaining health. Many individuals and their doctors know sleep is important, but they often do not identify sleep problems during routine doctors’ visits, and as a result, the problems are not sufficiently addressed. One obstacle to the convenient measurement of sleep is its complexity. A good night’s sleep depends on an individual’s daily rest and activity rhythms, the length and quality of their sleep, time spent in sleep stages (e.g., deep sleep versus rapid eye movement sleep), and their behaviors, such as maintaining a consistent bedtime. We do not know the specific patterns of sleep that place people at risk for – or protect them from – health problems. In addition, traditional ways of identifying sleep problems, such as spending the night in a sleep clinic, are often expensive or unavailable to many. This study will use wearable sleep monitors (i.e., similar to Fitbits) to identify the patterns of sleep that increase risk for health problems. As a first step, our team – including psychiatry, engineering, neurology, and sleep medicine specialists – will identify patterns that increase risk for mental health problems among adolescents, who are especially vulnerable to both sleep and psychiatric problems. We will also examine patients’ perceptions of the ease and acceptability of using wearable monitors to measure sleep in their health care setting. In the future, we hope to apply the patterns of sleep problems identified in this study to the detection of risk for a range of health problems for individuals of all ages.

Interrogation and Manipulation of Brain States through Real-time Analysis of Neural Activity

One of the great challenges in neuroscience is to understand how local groups of cells work together in circuits to generate complex behaviors. Historically, scientists have been limited to studying only a few of these cells at a time, yet new developments in microscope and imaging technology have recently made it possible to study much larger groups of cells. For some small animals such as the zebrafish, transparent in its larval state, it is possible to record the activity of nearly all brain cells at once. But there’s a downside: These new experiments can generate up to a terabyte of data an hour, enough to fill several hard drives per experiment! And often, the data from one day must be analyzed overnight on a computer cluster before the next experiment can start. The goal of our project is to remove much of this data analysis burden by using newly developed data processing methods and computer hardware to analyze the incoming brain signals in real time. Our goal is to perform so-called closed-loop, all-optical experiments, in which the incoming data change the experiment as it’s being run—a feedback loop. For example, we will be able to see how some neurons respond to visual information as the data are being collected and to stimulate these same neurons based on their response patterns. Methods like these promise to dramatically expand our understanding of how networks of brain cells function together, not only in healthy brains, but in those affected by neuropsychiatric diseases.

Early Language Development in the Visually Impaired

Children with high levels of hearing loss who receive late intervention usually have poor language outcomes, but children with high levels of vision loss generally attain language abilities akin to typically developing peers. Blind adults and older children have largely indistinguishable language abilities from sighted individuals, although research reports some brain differences in responses to auditory and linguistic stimuli; however, early language abilities in young blind children have been very little studied. This is significant, given that vision loss effects >75,000 children under age 4 in the U.S. One major roadblock to understanding early language abilities under visual impairment is the lack of methods that can be used across blind and sighted infants. Reports from parents can be informative, but they may be subject to parental opinion. Direct assessments provide a more accurate measure of children’s receptive vocabulary; however, standard eye-tracking approaches (which measure the time infants spend looking at named objects) are not possible in blind infants. We propose to extend to blind infants the auditory-based electro-encephalography (EEG) paradigms that have been well-established with infants and toddlers developing typically. Uncovering how blind children learn and represent words will reveal how sensory impairment fundamentally shapes the developing brain, which will in turn inform our understanding of cognition and language more generally. These results also will inform potential training regimens that can mitigate language delays and deficits in both children and adults.

Seven Projects Receive 2018 Germinator Research Awards

Photo: SeedlingbyNik@Unsplash

Interdisciplinary projects involve new approaches to neuroscience topics

Seven projects involving nearly two dozen Duke clinical and basic-science faculty, postdoctoral fellows, and graduate students have received the inaugural Germinator Research Awards from the Duke Institute for Brain Sciences (DIBS), the Institute’s Faculty Governance Committee Chair, Geraldine Dawson, announced today.

The awards grew out of DIBS Town Hall discussions, part of the strategic-planning process completed in February 2018. “We heard from the DIBS community the need to augment our larger grant program, the Incubator Research Awards, with support for small, targeted funding requests open to graduate students and postdoctoral fellows as well as faculty.” Dawson said. The Germinator Research Awards program was the result.

“These funded projects offer exciting new ways to encourage interdisciplinary approaches to important questions,” she added. Germinator projects receive up to a maximum of $25,000 and may go to single investigators. They must catalyze new research or collaboration and/or enhance chances of obtaining external funding.

2018 Germinator Award Recipients

Toward a Computational Psychiatry of Transdiagnostic Deficits in Cognitive Control
  • Christina Bejjani and Tobias Egner, Psychology & Neuroscience (P&N), Center for Cognitive Neuroscience (CCN); John Pearson, Biostatistics & Bioinformatics and CCN; Terrie E. Moffitt, P&N, Psychiatry & Behavioral  Sciences, Center for Genomic & Computational Biology (CGCB); Social Behaviour & Development, King’s College, London; Avshalom Caspi, P&N, Psychiatry & Behavioral Sciences, CGCB; Social Behaviour & Development, King’s College, London; and R. Alison Adcock, P&N, CCN, Psychiatry & Behavioral Sciences

This research project brings together the fields of psychiatry, developmental psychology, machine learning, biostatistics, cognitive psychology, and neuroscience with a goal of improving diagnosis and treatment of psychiatric disorders. The team will use computational psychiatry, a relatively new field described by the National Institute of Mental Health as “analytical approaches for the prediction of risk and treatment response and the understanding of the pathophysiology underlying mental disorders.” This could provide alternative methods of diagnosis, currently based primarily on external observed behaviors and self-reporting.

Effect of Connectivity-based rTMS and State-Dependency on Amygdala Activation
  • Lysianne Beynel, Nathan Kimbrel, Greg Appelbaum, Psychiatry & Behavioral Sciences; Simon Davis, Neurology

Post-traumatic stress disorder (PTSD) is can be highly debilitating, with low response rates to pharmacological treatment. Repetitive transcranial magnetic stimulation (rTMS), which uses magnetic fields to affect the brain, has demonstrated only modest efficacy. The shallow penetration of rTMS is insufficient to directly affect deep brain structures such as the amygdala, the brain area affected in PTSD. This team seeks to improve the therapeutic efficacy of rTMS for PTSD by reaching the amygdala indirectly, through its connections to other brain regions. Successful completion of this project could lead to significant long-term contributions to both clinical applications and mechanistic understanding of brain/behavior relationships. The project will involve Duke School of Medicine and the Durham VA Health Care System.

Eulemur as a Primate Model for Oxytocin System Evolution and Function
  • Nicholas Grebe and Christine Drea, Evolutionary Anthropology

Among closely related group-living primates of the genus Eulemur (lemurs, native to Madagascar), some male and female lemurs form monogamous pair bonds; others mate with multiple partners. This unique behavior may be related to the mammalian neuropeptide oxytocin, which facilitates formation and maintenance of social bonding. Being able to assess the comparative neuroendocrinology of pair-bonding in Eulemur will offer significant insights on how this neuropeptide works. This non-invasive research is a collaboration involving Evolutionary Anthropology and Biology and the Research Division of the Duke Lemur Center. It represents a new program of lemur brain science with potential implications for human behavior.

Testing a Neurocognitive Model of Emotional Distancing Using Transcranial Magnetic Stimulation
  • Kevin LaBar, P&N, CCN; Simon Davis, Neurology; Andrada Neacsiu, Psychiatry & Behavioral Sciences; John Powers, P&N

Emotion regulation is a core component of therapeutic approaches to alleviate distress associated with psychiatric disorders. Distancing is an emotion regulation strategy that relies on self-projection, or the ability to shift perspective from the here and now to a simulated time, place, or person. The team has developed a new model of the neurocognitive processes that contribute to distancing as a successful emotion regulation strategy. We aim to test this model using transcranial magnetic stimulation (TMS) in healthy adults.

A Flexible Neural Framework for Decision-Making Across Human Development:  Testing the Influence of Information and Arousal
  • Rosa Li, Duke Center for Interdisciplinary Decision Science, DIBS

Prevailing neural models of decision-making across human development propose that risk-taking peaks in adolescence due to a unique adolescent imbalance between cognitive control via the prefrontal cortex and reward-processing via limbic regions. Though such dual-systems models seem to fit neural data, they have not generated behavioral predictions borne out in the laboratory. One theory is that they fail to account for differences between laboratory and daily decisions related to relative levels of information available and arousal, or attentiveness. Dr. Li, a postdoctoral fellow, hypothesizes a more flexible neural model would yield better information to help understand adolescent neural circuitry and decision-making.

Virally Mediated Transduction of Light-Sensitive Ion Channels in Brainstem Motoneurons of Macaques
  • Marc A. Sommer and Martin O. Bohlen, Biomedical Engineering

This project will apply optogenetics, a biological technique to control neurons by using light, to non-human primates, with a goal of understanding more completely how nerve cells drive muscle activity. That could lead scientists to the ability to manipulate neuromuscular circuitry in non-human primates, an outcome that holds potential benefit to humans with neuromuscular diseases such as multiple sclerosis. The project also has a substantial education component for graduate students and medical students studying “Brain and Behavior” at Duke.

Restore Tactile Sensation and Proprioception in Lower Limb Amputees Using Epidural Spinal Cord Stimulation
  • Amol Yadav, postdoctoral associate, Muhammad Abd-El-Barr, and Nandan Lad, Neurosurgery; Tim Sell, Orthopedic Surgery; Paul Howell, Durham VA Health Care System, Physical Medicine and Rehabilitation Services

Amputation of a lower limb hinders movement significantly. Modern prosthetic leg technology helps, but cannot duplicate the ability of the human leg to relay vital sensory information to the brain about the body’s surroundings, nor can it address the often-intense “phantom pain,” which is pain felt in missing limbs, likely generated by the brain and spinal cord. A team of neurosurgeons, physical therapists, and rehabilitation medicine experts will work with amputees using spinal-cord stimulation to generate missing sensory information. The goals are to improve rehabilitation and control phantom pain. The project will involve the Duke School of Medicine and the Durham VA Health Care System.

Nicholas Institute Selects Five Duke Projects for Catalyst Program Seed Funding

Birds-eye view of agriculture

Five projects received funding in the second year of the Nicholas Institute for Environmental Policy Solutions’ Catalyst Program.

The program aims to build on the Nicholas Institute’s mission by increasing engagement with Duke University faculty to incubate and advance new partnerships, enhance policy-relevant knowledge, and create innovative policy solutions based on new creative synergies. Funded in the program’s second year:

Duke Infrastructure Course

Globally it is estimated that $3.3 trillion per year is needed in infrastructure investment, and that emerging economies account for roughly 60 percent of that investment need. This project lays the groundwork for developing an online curriculum at Duke University to consider the country-level social, environmental, and economic implications of infrastructure development and how to conduct social, environment, and economic project-level assessments. This course will target government officials and civil society organizations in developing countries receiving foreign and multilateral infrastructure investments through China’s Belt and Road Initiative (BRI).

Collaborators

Lydia Olander and Elizabeth Losos, Nicholas Institute for Environmental Policy Solutions; Erika Weinthal, Nicholas School of the Environment; Indermit Gill, Duke Center for International Development; Jackson Ewing, Nicholas Institute and the Sanford School of Public Policy; Matthew Rascoff, Duke Digital Education and Innovation

Assessing Rural Attitudes on the Environment

Rural Americans matter to the fate of U.S. environmental policy. Not only do farmers, ranchers, and forest owners manage huge portions of American lands and watersheds, but rural voters also have an outsized impact on policy, and in particular the United States Senate, which explicitly empowers rural states. This project aims to better understand rural Americans’ views on the environment, environmental policy, and environmentalism by understanding the attitudes of rural North Carolinians.

Collaborators

Robert Bonnie, Duke University’s Rubenstein Fellow Program; Tim Profeta, Nicholas Institute for Environmental Policy Solutions; Frederick Mayer, Sanford School of Public Policy; and Emily Pechar, Nicholas School of the Environment

Sustainable Seafood Program

This project aims to fully establish the Sustainable Seafood Program at the newly launched World Food Policy Center. With a second year of funding through the Catalyst Program, collaborators will finalize and submit a journal commentary paper on the need to incorporate discussion of “fish as food” into the global food policy dialogue. They will also develop a joint strategy with external partners and other international groups on how to shift the global policy discourse on this topic that will include crafting funding proposals to support research projects under the Sustainable Seaford Program.

Energy Transition Portal

Public utility commissions are shaping the landscape of the U.S. power system. They approve retail electricity rates, set “avoided cost” rates for utility purchases of small renewable generation projects, and, in traditionally regulated states, approve utility planning for retirements, new construction, and line upgrades. These actions have enormous consequences on the generation technologies utilities build and purchase, and their interest in investments to improve energy and facilitate the integration of distributed generation. This project will launch an interactive web portal describing America’s 55 public utilities commissions and tracking “grid of the future” proceedings, and leverage this portal for academic workshops and regulator training.

Practice Imperfect?

There is a widespread belief among expert practitioners that improved access to energy improves human development outcomes. However, social science literature is mixed and incomplete, with many causal pathways poorly elucidated. This project aims to compare expert and data-supported perspectives on the effect of energy access on social and economic development. It will develop a formal evidence library documenting the strength of evidence behind connections uncovered in the first year of the Catalyst Program-sponsored systematic review; formalize expert and practitioner understanding on these and other linkages, for comparison with claims and evidence in the literature; and support new data collection targeted at obtaining ground-based intuition on the relative importance of energy access and reliability in influencing the location and growth decisions of micro, small, and medium sized enterprises.

Energy Research Seed Fund Awards Eight Grants to Duke Faculty for 2018-2019

Energy Research Seed Fund

Research projects that explore advances in energy materials, novel perspectives on resilience and sustainability, and energy storage solutions will receive funding in 2018 from the Duke University Energy Initiative’s Energy Research Seed Fund.

The program will award eight grants to projects involving 21 faculty members from four Duke schools, investing a total of $336,956 in promising new energy research.

The Energy Initiative—Duke’s interdisciplinary hub for energy education, research, and engagement—expanded its program this year in response to faculty feedback, offering three distinct grant categories of research funding:

  • Seed grants of up to $45,000, intended to provide a financial head start for new multi-disciplinary, collaborative research teams, enabling them to produce preliminary results that may help them obtain future external funding
  • Stage-two grants of up to $35,000 to carry projects currently supported by Energy Initiative seed funding into their next research phase
  • Proposal development grants of up to $25,000 for past seed fund recipients to develop proposals for external funding

In this—the fifth annual round of funding—the Energy Initiative awarded six seed fund grants and one grant in each of the two new categories. The Initiative also increased the maximum requested amount for seed fund grants by $5,000.

The first three rounds of funding from the Energy Research Seed Fund totaled $667,000. As of fall 2017, those rounds had generated more than five times their value in follow-on awards for Duke research.

“Five years in, this program continues to deliver a remarkable return on investment for Duke University,” notes Energy Initiative director Brian Murray. “And faculty tell us that it’s sparking them to tap into colleagues’ expertise across disciplines. This year we wanted to continue to catalyze these collaborations organically, but we also wanted to invest in next-stage efforts more specifically focused on enhancing external funding potential. This new approach seemed to strike a chord, as the number of proposals were roughly double last year’s number. Narrowing that pool was truly a challenge for our reviewers, but this is a good challenge to have.”

The 2018 round of awards is co-funded by the Energy Initiative, the Office of the Provost, Trinity College of Arts & Sciences, Pratt School of Engineering, and the Information Initiative at Duke (iiD).

Funded Projects in 2018-2019

Seed Grants

So the Dam Doesn’t Break: Understanding Mini-Grid Infrastructure Sustainability in Nepal. Building on previous research on mini-grids, energy transitions, and public infrastructure, this project by Robyn Meeks (Sanford School of Public Policy), Dalia Patiño-Echeverri (Nicholas School of the Environment), Subhrendu Pattanayak (Sanford School of Public Policy), and Erik Wibbels (Political Science, Trinity College of Arts & Sciences) will examine how propositions from engineering, new institutional economics, and public finance could help explain variations in mini-grid success in Nepal. In the process, the team will produce new insights into solving the “infrastructure quality trap” in mini-grids, which experts see as essential to providing universal energy access by 2030.

Investigating the Stability of Promising Earth Abundant-Based Photoelectrochemical Energy Materials. Labs led by Jeffrey Glass (Electrical & Computer Engineering, Pratt School of Engineering), David Mitzi (Mechanical Engineering & Materials Science, Pratt School of Engineering), and Edgard Ngaboyamahina (Electrical & Computer Engineering, Pratt School of Engineering) will explore how a new earth-abundant material developed at Duke can improve the efficiency, cost-effectiveness, and stability of cathodes used to turn water into hydrogen gas that can be stored and used as fuel.

Enabling Better Energy Decisions through Better Interpretable Causal Inference Methods for Personalized Treatment Effects. Causal inference methodology has become an essential tool for determining energy policy and understanding energy usage dependencies. This project by Cynthia Rudin (Computer Science, Trinity College of Arts & Sciences), Sudeepa Roy (Computer Science, Trinity College of Arts & Sciences), and Alexander Volfovsky (Statistical Science, Trinity College of Arts & Sciences) will improve our ability to make policy decisions and understand energy use by making casual inference methods inspired by machine learning more flexible, scalable, and accurate.

Determining the Second-Life Potential of Used Data-Center Batteries. Backup batteries used in U.S. data centers may be a massive untapped resource for energy storage. They are lightly used, well-maintained, and are generally recycled long before their service life has ended. This wide-ranging collaboration from Lincoln Pratson (Nicholas School of the Environment), Josiah Knight (Mechanical Engineering & Materials Science, Pratt School of Engineering), Jim Gaston (Pratt School of Engineering), David Schaad (Civil & Environmental Engineering, Pratt School of Engineering), John Robinson (Nicholas School of the Environment), Dalia Patiño-Echeverri (Nicholas School of the Environment), Martin Brooke (Electrical & Computer Engineering, Pratt School of Engineering), and Casey Collins (Facilities), will test the storage capabilities of these used batteries to determine whether they may be suitable for applications such as storing intermittent renewable energy.

Increasing the Efficiency and Power Density of Redox Flow Batteries with Metal Nanowire Flow-Through Electrodes. Labs led by Benjamin Wiley (Chemistry, Trinity College of Arts & Sciences) and Jeffrey Glass (Electrical & Computer Engineering, Pratt School of Engineering) will improve the power density and reduce the cost of redox flow batteries through a new flow-through electrode from copper nanowires. The electrode will have the same permeability as graphite felt, but will be 2,000 times more conductive and less expensive.

High-Temperature Photocatalytic Reactions on Plasmonic Materials. Teams led by Jie Liu (Chemistry, Trinity College of Arts & Sciences) and Nico Hotz (Mechanical Engineering & Materials Science, Pratt School of Engineering) will develop and study a simultaneously plasmonic and catalytic material that can be used for high-temperature photocatalysis, a critical process in chemical conversion, fuel and electrical energy production, and pollution mitigation.

Stage-Two Grants

Compositional Engineering for High-Performance Perovskite Photovoltaics with Simplified Device Structure. David Mitzi (Mechanical Engineering & Materials Science, Pratt School of Engineering) and Jie Liu (Chemistry, Trinity College of Arts & Sciences) will build on prior research on perovskite solar cells.

Proposal Development Grants

Proposal to develop a 2018 Energy Frontier Research Center at Duke University. Michael Therien (Chemistry, Trinity College of Arts & Sciences) and David Beratan (Chemistry, Trinity College of Arts & Sciences) received funding to support the writing of three Energy Frontier Research Center (Department of Energy) grant proposals.

Duke Institute for Brain Sciences Selects Six Teams for Research Incubator Awards

Research Incubator Awards

Six interdisciplinary Duke faculty research teams have received 2017-2018 Research Incubator Awards from the Duke Institute for Brain Sciences (DIBS). The teams are addressing complex neuroscience issues such as temporal-lobe epilepsy, improved vision for people with prosthetic retinas, and better hearing for those with cochlear implants.

Three new and three existing projects were funded, for six awards—one more than was awarded in 2016-2017. The sixth award was made possible through the generosity of members of the DIBS External Advisory Board. Each team, new or continuing, will receive between $25,000 and $100,000, depending on the size, complexity, and costs for each project.

DIBS Research Incubator Awards provide seed funding to support interdisciplinary and collaborative brain science research within Duke for projects of exceptional innovation and broad significance to the field. The projects must engage at least two faculty representing multiple fields or levels of analysis and bring together investigators from across the university whose individual programs of research are not already connected.

This year’s teams represent more than a dozen disciplines from the campus and the School of Medicine, including anesthesiology, biochemistry, biomedical engineering, cell biology, chemistry, electrical and computer engineering, medicine, neurobiology, ophthalmology, pediatrics, pediatric neurology, psychology and neuroscience, and psychiatry and behavioral sciences. Both junior and senior faculty are participating, as are postdoctoral fellows.

Plans are underway for the 2018-2019 grant process. Updated information and application forms will be provided in early 2018. Please check the Research Incubator Awards page for details.

Following are the new and renewal teams and projects:

2017-2018 New Awards

Investigators

Drs. James McNamara (Neurobiology), Pei Zhou (Biochemistry), and Robert Anthony Mook (Medicine)

Title: Biochemical and Structural Characterization of Inhibitors of TrkB Signaling

Temporal lobe epilepsy (TLE) is a potentially devastating form of human epilepsy for which there is no prevention or cure. A single seizure can disrupt the TrkB signaling pathway, which initiates a chain reaction causing full-on epilepsy. If we can inhibit this chain reaction, we can prevent a single seizure from becoming a devastating illness. This project will explore molecules that inhibit this chain reaction in hopes of finding a prevention method.

Investigators

Drs. Sina Farsiu and Marc Sommer (Biomedical Engineering) and Lejla Vajzovic (Ophthalmology)

Title: Psychophysics-guided Signal Processing for Retinal Prosthetics

A visual prosthesis, or “bionic eye,” has provided some visual function to patients who were completely blind prior to implantation. A small camera worn externally takes pictures, converts them to electronic signals, and transmits them to an implantable retinal prosthesis. The resulting image has limited resolution due to hardware-design issues, and improving it would require costly development and approval of new devices. This project seeks to improve image resolution through advanced software design, a noninvasive, cost-efficient method that could be adapted to improve the vision of patients with retinal prostheses.

Investigators

Drs. Tobias Overath (Psychology & Neuroscience), Josh Stohl and Leslie Collins (Electrical & Computer Engineering), and Michael Murias (DIBS)

Title: Optimizing Cochlear Implant Sound Processor Configurations via Neural Response Properties to Improve Speech Comprehension

Nearly one million Americans are functionally deaf and an additional 400,000 are deaf in one ear. The cochlear implant (CI) is the most successful sensory prosthetic implant to help them regain hearing; about 500,000 people in the U.S. have the implants. For many, CIs achieve near-perfect speech comprehension in ideal listening situations. For others, CIs work less well, and adjustments require lengthy appointments. This project aims to optimize CI configuration by recording neural impulses while the patient is listening to speech. Once neural responses are collected, they may be used to reprogram the CI and enhance the implant’s performance, reducing the need for repeated adjustments.

2017-2018 Renewal Awards

Investigators

Drs. Niccolò Terrando and Miles Berger (Anesthesiology), Warren Grill (Biomedical Engineering), Christina Williams (Psychology & Neuroscience), Chay Kuo (Cell Biology), and William Wetsel (Psychiatry & Behavioral Sciences)

Title: Bioelectronic Medicine and Cholinergic Regulation of Postoperative Cognitive Dysfunction

Memory dysfunction is a common postsurgical complication and may last for several months, even years. We do not yet know why this decline in memory function occurs, and there is no effective medical treatment to prevent it. The research team has developed a clinically relevant model to study surgery-induced memory dysfunction in mice after a common type of orthopedic surgery. This project will identify cellular processes that may cause postsurgery memory deficits, focusing on interactions between the nervous and immune systems. This work could have a major impact on global health by reducing postoperative cognitive dysfunction.

Investigators

Drs. Mohamad Mikati (Pediatrics, Neurobiology), Dwight Koeberl (Pediatrics), Scott Moore (Psychiatry & Behavioral Sciences), and William Wetsel (Psychiatry & Behavioral Sciences)

Title: Mechanisms of Increased Hippocampal Excitability in the D801N Knock-in Mouse Model of Na/K ATPase Dysfunction and Rescue with AAV-mediated Gene Therapy

Fifty percent of the energy consumed by brain cells is expended by a cellular pump called the sodium-potassium (chemical symbols: Na/K) ATPase pump. This pump, critical for maintaining the integrity and function of brain cells, is vulnerable to malfunction under stress associated with conditions such as epilepsy and stroke, and others, including alternating hemiplegia of childhood (AHC). AHC is a severe disorder causing paralysis, spasms, and epileptic seizures. It is caused by a genetic mutation that codes for a protein in the pump. Using a mouse model with the most common AHC mutation and the disorder, the team will investigate the cell circuitry regulating the pump mechanism. The team will next attempt to use gene therapy to correct the malfunction in the mouse model, which may lead to new therapies for humans with AHC, epilepsy, and related conditions.

Investigators

Drs. Yiyang Gong (Biomedical Engineering), Jinghao Lu, Fan Wang, and Diming Zhang (Neurobiology)

Title: Building a Fiber-integrated Microscope System for Two-color Optogenetic Probing of Ensemble Activity in Freely Behaving Animals

Every thought or movement made by our brains requires many neurons. To understand even basic brain function, we must be able to record the activity of many neurons at once. This project will use the techniques of optogenetics and optical engineering to allow researchers to see neurons while they are active. Thus far, this team has developed a mini-microscope that can visualize one type of neurons at a time in awake and moving mice. The next step requires examining multiple types of neurons interacting together.

With D-SIGN Grants, Graduate Students Build Networks and Advance Research Interests

D-SIGN Duke grantees

Five groups led by Duke graduate students received Duke Support for Interdisciplinary Graduate Networks (D-SIGN) grants for the 2016-17 academic year, becoming the first cohort of students to make use of this new program from the Office of the Vice Provost for Interdisciplinary Studies. D-SIGN’s purpose is to enable graduate students to build or extend their networks and to integrate collaborative, cross-school experiences into their programs, thereby increasing the number of individuals whose graduate training reflects Duke’s commitment to interdisciplinarity and knowledge in the service of society.

The D-SIGN grantees included students from the School of Nursing, Sanford School of Public Policy, Arts & Sciences and the Nicholas School of the Environment who advanced a range of research projects and educational experiences that reach beyond disciplinary lines. Here are brief summaries of the groups’ activities.

Global Alliance on Disability and Health Innovation (GANDHI) – Children and Adolescents Health Group

Brittney Sullivan (Ph.D. in Nursing ’17, School of Nursing) and Anna Martin (Master of Public Policy student, Sanford School of Public Policy), established a graduate network affiliated with the Bass Connections project Global Alliance on Disability and Health Innovation (GANDHI) but focused on young people rather than adults. Their faculty sponsor was Janet Prvu Bettger (Nursing).

They aimed to establish the evidence for improving systems of care for children and adolescents living with disability after an acute hospitalization. Using a socioecological approach to identify the key needs for children newly living with disability, network members set out to examine and compare the social supports, health and community services and policies in three countries.

The group held weekly meetings with guest speakers throughout the year, supplemented by four group dinners. Three members traveled to Uganda in April to conduct interviews and observe some of the organizations that the group identified.

Anna Martin and Nelia Ekeji ’19 presented “GIS Study of Posthospital Services Supporting Children with Surgical Need in Uganda” at a Duke event, Strategies to Strengthen Health Systems Globally.

The group has a manuscript in preparation, “Spatial Distribution of Rehabilitation Services for Children Following Surgery in Uganda: Using the Data to Plan Interventions.” Members are transcribing and coding interviews, and Sarah Barton (Th.D. student, Divinity School) will lead the group in 2017-18.

Global Energy Access Network (GLEAN)

Three graduate students teamed up with faculty sponsors Subhrendu Pattanayak (Sanford School of Public Policy) and Brian Murray (Nicholas School of the Environment) to bring together students across Duke who are working on global energy transitions, energy access and energy poverty.

Rob Fetter and Faraz Usmani (University Ph.D. Program in Environmental Policy students, Nicholas School and Sanford School) and Hannah Girardeau (Master of Environmental Management student, Nicholas School) established GLEAN to ignite a research and policy dialogue around an understudied global issue.

GLEAN has grown into a network of 50 graduate and undergraduate students, representing at least seven schools and departments across Duke. Members met once or twice each month to update the broader community about relevant activities taking place at their respective schools and departments.

Through the Energy Access Speaker Series, GLEAN organized seven talks by experts on energy, environment and development. Five of these events were co-organized with other Duke programs, which helped the members to forge new partnerships.

In June, the group published an edited volume of energy access case studies, Energy & Development. The six chapters are coauthored by graduate or undergraduate students and focus on five countries (India, Indonesia, Madagascar, Nicaragua, Peru). With support from the Duke University Energy Initiative—GLEAN’s institutional home—the group will promote the publication widely this fall.

Several members worked with three paid research associates to compile a detailed annotated bibliography of energy, environment and development data sources available publicly that will be useful in creating an Energy Access Index. The group received a follow-on D-SIGN grant to conduct an energy access and air quality survey, engage two keynote speakers, produce case studies on energy and development and coordinate an “Imagine Energy” photo contest and exhibition.

Rethinking Regulation – Graduate Student Working Group

Based in the Rethinking Regulation Program at the Kenan Institute for Ethics, this group provides a forum for student-led interdisciplinary discussion, research and analysis of issues related to regulatory governance. Mercy DeMenno (Ph.D. in Public Policy student, Sanford School) sought a D-SIGN grant to support research workshops, writing group meetings, analyses of contemporary regulatory policy issues and other collaborative activities.

The group has grown to involve 25 students from 13 disciplines/programs and nine schools/departments as well as an active alumni group. Faculty sponsors are Lori Bennear (Nicholas School) and Jonathan Wiener (Law).

The group convened 12 research workshops in which members received feedback on their conference papers, articles, dissertation proposals, chapters and research plans. Presentations covered a range of topics, including regulatory impact assessment, regulatory disclosure regimes for fracking, regulating household energy technology, private accreditation in education, water and sanitation service provision in the Middle East and tort reform.

In addition, the group convened two writing groups that met twice per month. One group focused on dissertation prospectus and grant proposal development while the other focused on dissertation articles, chapters and extensions.

A key initiative was the development of a student-led regulatory governance blog. The Rethinking Regulation Blog publishes short articles connecting scholarly work to contemporary regulatory policy issues, with an emphasis on interdisciplinary, collaborative and applied academic inquiry.

A STEM Researcher-Educator Network to Improve K-12 Science Literacy

Three doctoral students teamed up with faculty sponsors Kate Allman (Program in Education) and Brad Murray (Nicholas School) to create a network of STEM graduate students and Master of Arts in Teaching students who work together on lesson plans for local K-12 educators. Rebecca Lauzon (Ph.D. in Earth and Ocean Sciences student, Nicholas School), Eleanor Caves and Patrick Green (Ph.D. in Biology students, Arts & Sciences) utilized the structure of the Scientific Research and Education Network (SciREN), which develops relationships between researchers and educators to incorporate current research into K-12 classrooms.

They recruited two MAT students and 17 STEM researchers to develop K-12 lesson plans. The network produced 16 lesson plans, which were shared with 150 educators at SciREN’s annual networking event and added to SciREN’s portal.

“Polymers Matter” and “Modeling Cell Organelles” were selected for inclusion in SciREN’s lesson plan kit program. Educators were able to order these lessons and have all the necessary supplies mailed. These two lessons reached six schools and 400 students. “Exploring Marshes and Barrier Islands with a Scientific Model” and “Make It Rain: The Water Utility Management Game” were shared with an additional 50 educators at SciREN Coast, an educator-researcher networking event organized by the Duke and UNC marine labs.

The group organized two workshops for STEM researchers. Sixty people attended Demystifying STEM Outreach. Getting Down to Basics: Strategies for Communicating Complex Science was an interactive workshop for 25 students. From these events, the group produced a database of outreach/science communication opportunities.

Pre- and post-surveys revealed that after participating in the network, STEM graduate students felt more qualified to do outreach with K-12 students and educators and to create lesson plans. The MAT students felt they built a network of scientists and gained experience-planning lessons on complicated subjects.

Duke Conservation Society

With faculty sponsor Stuart Pimm (Nicholas School), Priya Ranganathan (Master of Environmental Management student, Nicholas School) sought a D-SIGN grant to expand the Duke Conservation Society beyond the Nicholas School to engage interdisciplinary approaches to conservation.

The group’s mission is to enhance students’ understanding of the various scientific, political, economic and managerial tools available to address conservation issues; facilitate collaborations among undergraduate, master’s and Ph.D. students on conservation projects and analyses; and provide opportunities for professional development such as networking with conservation professionals, seminars and guest speakers.

The Duke Conservation Society organized multiple symposia and events geared toward sharing international perspectives on conservation. Members worked with Conservation X Labs, a company that produces technology for wildlife conservation, and Duke Conservation Tech, a student organization affiliated with the Pratt School of Engineering, to produce Blueprint: People + Wildlife. This was a competition for teams of undergraduate and graduate students in the Triangle area to create blueprints for novel conservation technologies to assist in fighting the illegal wildlife trade. Approximately 50 students participated in teams.

The group also used the D-SIGN grant to for a dinner seminar to discuss a project on urban gardening that the Divinity School and the Nicholas School will undertake together. The dinner featured Saskia Cornes of the Duke Campus Farm and Norman Wirzba of the Divinity School. The speakers discussed the intersection of conservation, urban agriculture and Christianity, and students from both schools collaborated on designs for the proposed courtyard garden at the Divinity School.

Read about the six groups that received D-SIGN grants for 2017-18 and what they plan to do. The next call for proposals will be released in early 2018. Any current Duke graduate student (including master’s, professional and Ph.D. students) may submit a proposal for interdisciplinary projects, trainings or experiences during the 2018-19 academic year.

Six Graduate Student Groups Receive Interdisciplinary D-SIGN Grants

The Office of the Vice Provost for Interdisciplinary Studies has awarded Duke Support for Interdisciplinary Graduate Networks (D-SIGN) grants to six graduate student groups for the 2017-2018 academic year.

Desarrolla México

  • Student organizers: Ruxandra Popovici, Ph.D. in Environment, Nicholas School of the Environment; Emilio Blanco Gonzalez and Adam Cullen, Master of Engineering in Mechanical Engineering, Pratt School of Engineering

Desarrolla México is one of five projects developed by Duke Desarrolla. This group will conduct a summer project in Ejido Playa Grande, helping a rural community develop a renewable energy strategy and a formal business plan for its environmentally sustainable ecotourism business. In doing so, the group aims to promote a consultant-based approach to international development, connecting community members to business, marketing and engineering experts who can help them reach their particular business goals. This project is part of a research study on the obstacles faced by rural residents when attempting to reinvest funds received from Payments for Ecosystem Services programs into a community business. (See update.)

Global Energy Access Network (GLEAN)

  • Student organizers: Yating Li, Ph.D. in Environmental Policy, Nicholas School of the Environment and Sanford School of Public Policy; Muye Ru, Ph.D. in Earth and Ocean Sciences, Nicholas School of the Environment; Faraz Usmani, Ph.D. in Environmental Policy, Nicholas School of the Environment and Sanford School of Public Policy; Heidi Vreeland, Ph.D. in Civil and Environmental Engineering, Pratt School of Engineering

GLEAN includes more than 50 graduate and professional students from across Duke. The group received a D-SIGN grant last year and will use this follow-on grant to elevate the prominence of the global energy access challenge on campus; foster an interdisciplinary community of graduate and professional students wanting to engage with this challenge in their work; and offer opportunities to this community to do so. Activities will include an energy access and air quality survey, engagement with two keynote speakers, case studies on energy and development and an “Imagine Energy” photo contest and exhibition. (See update.)

The Global South after 2010

  • Student organizers: Renee Ragin, Ph.D. in Literature, Arts & Sciences; Giulia Ricco, Ph.D. in Romance Studies, Arts & Sciences

This group will explore the aesthetics, ethics and politics of transnational violence in the Global South. Are there systematic trends in the types of sociopolitical violence that have characterized social movements after the Arab Spring? How has this violence been represented in the media and in popular culture? What are the legal and political consequences of such representations? Activities will include three seminars with guest facilitators and a graduate student conference. Student participants will come from humanities and social science programs in the Graduate School, as well as from Fuqua, Sanford and Law. The organizers aim to create an edited anthology at the conclusion of this working group. (See update.)

Lowndes County Sanitation Access Network

  • Student organizers: Emily Meza, Master of Environmental Management, Nicholas School of the Environment; Katy Hansen, Ph.D. in Environmental Policy, Nicholas School of the Environment and Sanford School of Public Policy; Ryan Juskus, Ph.D. in Religion, Arts & Sciences

Students from Divinity, Law, Nicholas, Pratt and Sanford will undertake a community-based research project to improve wastewater treatment in Lowndes County, Alabama, where 90% of households have inadequate or no access to sanitation. More than 80% of households cannot connect to the municipal sewerage and must finance their own septic systems. With a median household income among the lowest in the U.S., many households cannot afford to do so. In addition, half of the septic systems are failing. Poor sanitation poses serious health risks (including hookworm, found in fecal samples from Lowndes County residents). The group will take the lead in diagnosing the interlaced physical, financial, legal and political barriers to sanitation access and evaluate potential solutions. (See update.)

Modeling Health & Environment Graduate Working Group

  • Student organizers: Shashika Bandara, Master of Science in Global Health, Duke Global Health Institute; Varun Mallampalli, Ph.D. in Civil and Environmental Engineering, Pratt School of Engineering

A working group of graduate students from diverse backgrounds will design a course for undergraduates on systems thinking and modeling in health and environment. Graduate students with backgrounds in energy, environmental studies and health will collaboratively develop instructional models based on real-world case studies that will serve as course materials for the undergraduate course. Through their interdisciplinary collaboration and the process of contributing to the course, the graduate students will acquire system dynamics modeling skills as well as relevant subject matter knowledge on global health, the environment and the interconnections between the two. (See update.)

Network to Enrich GALS Summer Science Program

  • Student organizers: Jacqueline Gerson, Ph.D. in Ecology, Arts & Sciences; Emily Levy, Ph.D. in Biology, Arts & Sciences

This summer, the Girls on outdoor Adventures in Leadership and Science (GALS) group is piloting a free two-week summer camp for girls aged 15-18 from underrepresented backgrounds to encourage them to pursue STEM fields. The D-SIGN grant will be used to improve the training of GALS leaders and foster a community of environmental educators for a broad array of disciplines. Activities include facilitating interdisciplinary working groups to improve lesson plans and the structure of GALS; expanding resources for GALS leaders and increasing the number of leaders; sharing the curriculum and logistics to encourage similar programs across North Carolina; and creating mentorship programs between Duke students from underserved communities and GALS participants. (See update.)

About D-SIGN

This internal funding mechanism encourages graduate students to explore beyond disciplinary lines, both in research and coursework. The goal is to enable graduate students to build or extend their networks and to integrate collaborative, cross-school experiences into their programs, thereby increasing the number of individuals whose graduate training reflects Duke’s commitment to interdisciplinarity and knowledge in the service of society.

A January 2017 RFP invited all current Duke graduate students (including master’s, professional and Ph.D. students) to propose an interdisciplinary project, training or experience lasting up to a year.

Proposals were reviewed by an ad hoc committee convened by the Vice Provost for Interdisciplinary Studies with representation from faculty, institute directors and graduate students.

The first cohort of D-SIGN grantees (2016-2017) included Duke Conservation Society; Global Alliance on Disability and Health Innovation – Children and Adolescents Project; Global Energy Access Network (GLEAN); Rethinking Regulation – Graduate Student Working Group; and A STEM Researcher-Educator Network to Improve K-12 Science Literacy.
