Four groups led by Duke University faculty have been awarded Collaboratory grants for research into pressing local and global challenges.
“From investigations in our own backyard into evaluating water safety and lessening the impact of evictions on child development, to research aimed at increasing solar energy efficiency and minimizing the spread of infectious diseases on a global scale, these proposals speak to our dedication to improving the human condition,” said Provost Sally Kornbluth. “Supporting faculty research is an essential way to advance the fundamental learning and discovery at which we excel, and those investments provide ripple effects that benefit teaching and service.”
The grant period is one year with a possibility of renewal.
Drinking Water Contamination in North Carolina: Water Use, Human Health, and Going Beyond GenX
- Principal Investigators: Heather M. Stapleton, Nicholas School of the Environment; Lee Ferguson, Pratt School of Engineering and Nicholas School of the Environment
- Additional Team Members: Kate Hoffman, Kateri Salk, Nicholas Herkert, Nicholas School of the Environment; Liping Feng, School of Medicine; Kay Jowers and Amy Pickle, Nicholas Institute for Environmental Policy Solutions; Samantha Hall and Christine Crute, Ph.D. students in Integrated Toxicology and Environmental Health; additional students
Changes in water availability, increases in pollution, and policy regulations are resulting in substantial challenges for water protection, and consumers bear the social and economic burden when drinking water sources are contaminated. One of the most relevant threats to public drinking water in the U.S. is a class of chemicals called poly- and perfluoroalkyl substances (PFASs). These chemicals made local headlines in 2017 when news stations reported contamination of drinking water wells with “GenX” in New Hanover and Brunswick counties.
In 2018, the state legislature appropriated several million dollars for testing all surface waters across the state. Despite the broad documentation of PFAS contamination, no funding was included to evaluate health impacts on affected communities or to identify sources.
This collaboratory will build a water model to help identify potential point source(s) of PFAS contamination, and underlying variables influencing the water levels, in the Piedmont region. In addition, the researchers will examine the relationship between water levels and biological PFAS levels, and conduct geospatial analyses to determine if poorer health outcomes at birth are associated with areas of higher PFAS contamination. The group will also investigate effects of PFAS on birth outcomes using an animal model, and integrate environmental and human health knowledge into management and policy recommendations regarding water use policies.
Minimizing the Influence of Air Pollution on Solar Energy Production
- Principal Investigators: Mike Bergin, David Carlson, Mark Wiesner, David Mitzi, and William Walker, Pratt School of Engineering; Drew Shindell, Brian Murray, and Gaby Katul, Nicholas School of the Environment; Kyle Bradbury, Energy Initiative; Steven Sexton, Sanford School of Public Policy
Particulate matter, including air pollution and dust, has dramatic impacts on both climate and human health. It also reduces solar energy production by about 15% on a global average and as much as 40% in some regions. This current loss in efficiency is estimated to account for the loss of power output valued in the tens of billions of dollars annually, dramatically affecting cost effectiveness and renewable energy access. The problem is not well understood and few studies are available that quantify the impacts, although it will become increasingly important with solar power production expected to increase globally by nearly four-fold over the next 20 years.
This collaboratory will assess the regional impacts of air pollution on solar energy production, determine cost-effective strategies to minimize the influence of particulate matter on solar energy production, and develop and test novel surfaces and coatings that hold great promise in minimizing the influence of deposited particulate matter on solar energy production.
Evaluating and Mitigating the Impact of Evictions and Other Housing Insecurity Issues over Health and Child Development in North Carolina
- Principal Investigators: Anna Gassman-Pines, Elizabeth Gifford, and Marcos Rangel, Sanford School of Public Policy; Kay Jowers, Nicholas Institute for Environmental Policy Solutions; Christopher Timmins, Economics, Trinity College of Arts & Sciences; Naomi Duke, School of Medicine
- Additional Team Members: Jillian Hurst, School of Medicine; Sarah Dickerson, postdoctoral associate, Sanford School of Public Policy; graduate and professional students
In the U.S., 10-15% of households experience housing insecurity. For families with young children, this number is much higher. Lack of secure housing is associated with a host of health consequences including psychological distress and exacerbating chronic conditions. For children, housing instability is associated with increased problem behaviors, respiratory conditions, infectious diseases, and decreased access to healthcare. In Durham, 16% of children aged 0-8 live in a household where housing costs exceed 50% of the household income—leaving few resources for other needs such as food, clothing, and transportation.
This collaboratory brings together a multidisciplinary team to study how housing insecurity affects children’s health and education and what policy solutions may be implemented to mitigate the associated harms. To inform evidence-based policies and help communities promote population-level health, this study will assess patterns of population movement in Durham County and the relationship of these patterns with housing insecurity, examine the effects of housing insecurity and evictions on the education of children across North Carolina and in Durham County specifically, and investigate the effects of housing insecurity and evictions on children’s healthcare utilization and health status in Durham County.
Identifying Infectious Disease Transmission Pathways for Improved Population Health and Pandemic Preparedness
- Principal Investigators: Charles L. Nunn, Evolutionary Anthropology, Trinity College of Arts & Sciences; Randall Kramer, Nicholas School of the Environment; James Moody, Sociology, Trinity College of Arts & Sciences; Linfa Wang, Duke-NUS Medical School
- Additional Team Members: Alma Solis, Ph.D. student in Evolutionary Anthropology; other graduate students
The title of a recent high-profile Commentary in Nature proclaimed, “Pandemics: Spend on surveillance, not prediction.” If resources and time were unlimited, scientists would exhaustively sample wild animals, domesticated animals, and humans, and they would fully investigate the ecological contexts in which transmission occurs; all of these foci are crucial for predicting disease emergence. Given the reality of limited resources, new approaches are needed to deepen understanding of disease transmission pathways from animals to humans.
This collaboratory will use new surveillance tools and apply analytical frameworks from network epidemiology to disentangle the drivers of disease transmission at the human-animal ecological interface. The group’s research takes place in rural Madagascar. Members will collect and analyze blood samples and expand socioeconomic data collection; this research will provide crucial pilot data to increase the competitiveness of external grant submissions, while also providing opportunities for students involved in the research to publish early findings and present those findings at conferences. In addition to collecting data in the field and shipping samples to Singapore for analysis, funding will enable us to develop new analytical pipelines for network epidemiological analyses, including with graduate students on Duke’s campus.
