Michael S. Gaffrey, Ph.D. is an Assistant Professor at Duke University in the Department of Psychology & Neuroscience. He is also Director of Duke’s Early Experience and the Developing Brain (DEED) lab. He received his Ph.D. in Clinical Psychology from the University of Wisconsin, Milwaukee and completed a postdoctoral fellowship in developmental clinical and affective neuroscience at the Washington University School of Medicine. Dr. Gaffrey has also completed advanced training in infant mental health practice and policy through the ZERO-TO-THREE Leadership Development Institute.
Dr. Gaffrey is firmly committed to studying, treating, and advocating for the health and well-being of vulnerable infants and young children. To this end, his research endeavors include the use of behavioral and neuroimaging methodologies to better understand biological pathways underlying risk and resilience to early life stress and related environmental challenges. He is also actively involved in using the tools of developmental neuroscience to better understand how preventive intervention programs targeting infants at risk for negative socioemotional outcomes, including depression and autism spectrum disorder, can be used more effectively. Through the integration of clinical practice and innovative research, Dr. Gaffrey hopes to reduce the impact of risk factors that contribute to unfavorable health outcomes for vulnerable infants and families. Furthermore, Dr. Gaffrey believes we can better foster healthy environments for growing children and ensure the well-being of all infants and families by bringing objective research and practice-based knowledge to policy and public arenas.
Yu Sun Chung, Ph.D. received her Ph.D. in Behavior, Brain and Cognition program from Washington University in St. Louis under the supervisions of Drs. Deanna Barch and Todd Braver, along with Cognitive, Computational and Systems Neuroscience training. Her overall research program has focused on understanding normal and abnormal behaviors supported by frontal-limbic circuitry. Specifically, during her graduate years, her work focused on cognitive control of reward processing and anhedonia in schizophrenia and healthy adults using fMRI and behavioral paradigms. To fully understand the onset of psychopathology that typically develops in adolescence, she completed her first postdoctoral training in developmental cognitive neuroscience at Olin Neuropsychiatry Research Center, Hartford, CT. During the time, she investigated sex-specific adolescent developments of response inhibition and emotion regulation using various functional connectivity methods and salivary hormone assessments. In the DEED lab, she primarily works on the Neurodevelopmental Trajectories of Reward Processing in Very Early Emerging Risk for Depression study. She is extending her skillsets to use the combination of fMRI and ERP to better delineate early developments of self-regulation and emotion in preschoolers in a sex-specific way. Her research program’s ultimate goal is to understand sex-specific neural developments of emotion, cognition, and reward processing from children through adolescence to young adults in order to develop individualized treatments for dysfunctions in emotion and cognition at the early developmental stages of psychopathology.
Carina Fowler, B.A. is a second-year Ph.D. student in Duke’s clinical psychology program. A Washington University in St. Louis graduate, she comes to the DEED Lab after working as a Project Coordinator at neighboring UNC-Chapel Hill.

In her free time, Carina likes to read–especially a good mystery!
Sarah Markert, B.S. is a first-year Ph.D. student in Duke’s Clinical Psychology Program. She graduated from the University of Pittsburgh in 2017, where she completed an Honors Thesis that investigated mechanisms of language development within the caregiver-infant dyad in infants at high and low risk for ASD. After graduation, she spent two years researching early social visual engagement in infants with and without ASD as a Donald J. Cohen Fellow in Developmental Social Neuroscience at Emory University’s Marcus Autism Center. Now in the DEED lab, she is excited to continue to research the dynamic and mutually-reinforcing nature of the caregiver-infant dyad, targeting shifts in social visual attention using dyadic head-mounted eye tracking technology. She plans to involve her clinical and scientific work in facilitating and researching the MC2 intervention to help promote healthy foundations for vulnerable infants and families in the community and at large. In her free time, Sarah loves seeing live music and de-stressing with her cat Gouda.
Armen Bagdasarov, B.A. is a first-year Ph.D. student in Duke’s clinical psychology program. He graduated from the University of Pennsylvania in 2018, the first in his family to attend college.

In the DEED lab, Armen is excited to integrate EEG and fMRI to better understand the development of neural networks and concurrent changes in behavior. He is also interested in studying how early life stress and adversity affect neural networks and increase risk for mental disorders. In his free time, Armen enjoys cooking and kickboxing!
Nicolas L. Camacho, B.S. is a first-year Ph.D. student in Duke’s Clinical Psychology Program. He graduated from Columbia University in 2016. As an undergraduate, he held volunteer and internship positions at organizations such as Autism Speaks, the Manhattan Children’s Center, and NY-Presbyterian Hospital’s Center for Autism and the Developing Brain. After graduating from Columbia, Nicolas was a research assistant on the Child Mind Institute’s Healthy Brain Network research study, where he worked with clinical researchers to conduct language, learning, and mental health evaluations for children, adolescents, and young adults. Extending his post-bacc experiences for another two years before pursuing graduate studies, Nicolas went on to work as a lab manager in Professor Nim Tottenham’s Developmental Affective Neuroscience Lab at Columbia University. In this position, he managed a large team of researchers on an NIMH-funded R01 longitudinal, high-dimensional, multi-modal (neuroimaging, behavior, caregiver report, physiology) study of school-aged children with heterogeneous exposures to early caregiving adversities. At the DEED Lab, Nicolas plans to study the neurodevelopmental trajectories and related cognitive abilities that may place young children at greater risk of developing depression. Nicolas hopes to effectively investigate and provide personalized treatment options for children with mood disorders in the future. In his free time, Nicolas likes to hike, rock climb, read, and watch foreign-language films.
Ellen Gaffrey, M.S. received her Bachelor of Arts degree in Education/Special Education from Cardinal Stritch University and her Masters of Science degree in Administrative Leadership from the University of Wisconsin-Milwaukee.

Margaret O’Brien, M.S. is a Durham native, who received her BS in Psychology from the University of North Carolina (UNC) in 2013 and her MS in Psychology from the University of Illinois in 2018. She has worked for many years in the fields of Developmental Psychology and Cognitive Neuroscience, and has a particular interest in emotion-cognition interactions throughout the life span. Margaret’s Honor’s Thesis at UNC investigated age- and gender-related differences in attentional and perceptual patterns in 9 and 12 month old infants using an infant-controlled habituation paradigm. Her Master’s Thesis at the University of Illinois used Eye Tracking to investigate attentional shifts in emotion regulation, and subsequent item and relational memory for emotional images. Within the DEED lab, Margaret works most closely with the Eye Tracking components of the Dyadic Head-Mounted Eye Tracking (DH-MET) study, investigating social and attentional changes in children with (or at risk for) Autism Spectrum Disorder.
Summer Lawrence, B.S. received her Bachelor of Science degree in Psychology with a minor in Sociology from Virginia Tech in 2018. During her time at Virginia Tech, Summer worked as an undergraduate researcher for three years in the Social Development Lab under the supervision of Dr. Julie Dunsmore. She was involved in multiple aspects of research relating to emotion regulation, coaching, and intelligence. She also worked on projects that looked at the effects a person’s family and peer groups have on their emotional development. Within the DEED lab, Summer primarily works on the Neurodevelopmental Trajectories of Reward Processing in Very Early Emerging Risk for Depression study. This study investigates development and risk for depression. She also assists with collecting EEG data and coordinating fMRI scans with preschoolers and their parents.
