Postdoctoral Fellows


Kendra Seaman

Kendra Seaman is a Postdoctoral Scholar at Duke University, funded by T32 AG000029-41 through the Center for the Study of Aging and Human Development, doing research in the MCAB Lab.  Her research examines the intersections of learning, motivation, and decision making across the adult life span using behavioral, modeling and neuroimaging techniques. Prior to earning her Ph.D., she served as a Teach For America corps member, teaching science at Frick Middle School in Oakland, California, and as a teacher and department chair at KIPP DC: KEY Academy in Washington, DC



Linh Dang

Linh received a PhD in Neuroscience at UC Berkeley where she worked primarily with Bill Jagust. She is currently a post-doctoral fellow at Vanderbilt University in the Zald Affective Neuroscience lab. She collaborates heavily with our lab on several studies examining links between individual differences in the dopamine system (using PET imaging) and functional neural activity (using fMRI).



Matthew nassar

Matt is a post-doctoral fellow at Brown University. He collaborates with our lab on projects related to computational models of learning across adulthood. 



Christopher Smith

Chris received his PhD in Neurobiology from UNC Chapel Hill, where he worked with Charlotte Boettiger. He is currently a post-doctoral fellow at Vanderbilt University in the Zald Lab at Vanderbilt and collaborates with our lab on PET imaging studies of the dopamine system. 


Graduate Students

Jaime is a PhD student at Duke supported by an NSF Graduate Research Fellowship. He was an undergraduate at USC, research assistant at Vanderbilt, and lab manager at UCLA. He is interested in decision neuroscience and how neuroscience can inform public policy and law.



Eric Juarez

Eric is a PhD student at Duke supported by a Dean's Graduate Fellowship. He was an undergraduate at Harvard. He is interested in memory and decision making across the life span especially as it relates to health behavior.


nadia brashier

Nadia is a graduate student at Duke working primarily with Elizabeth Marsh. She earned a B.S. in Psychology from Davidson College. She is interested in memory and judgment across the life span, with a specific focus on how we judge truth.


Teresa Karrer

Teresa completed her masters thesis in our lab as a scholar of the German National Academic Foundation. As a PhD student at RWTH Aachen University, she continues to collaborate on projects related to neuromodulation and decision making across the life span.

Research Assistants


Mikella Green

Mikella is a lab manager and project coordinator. She received her BA in Psychology from Duke University in 2017. She is interested in how memory changes with age and the development of clinical interventions.


Galen McAllister

Galen is lab manager and project coordinator. He was in the lab as an undergraduate at Yale (BA in Psychology 2017). He is interested in the neurobiology of craving and how mindfulness strategies affect impulsivity in decision making.


Eliana Armora

Eliana (Duke '18) is a Neuroscience and Global Health double major. She is interested in the relationship between health behaviors, cognition, and mental health. 


ZACHARY spiera

Zachary (Duke '18) is a Neuroscience major. He is interested in how laboratory research on decision making can be applied to broad scale social problems. 


MIcaela brewington

Micaela (Duke ’19) is a Neuroscience and Global Health double major with a minor in French. She is interested in how cognitive processes influence behavior change, particularly concerning public health promotion.


Natalia Espinosa

Natalia (Duke '19) is a Neuroscience major with minors in Computer Science and Cultural Anthropology. She is interested in how motivation influences cognition, as well as the ethical implications of neuroscience. 


Sammy Garland

Sammy (Duke '20) is a Computer Science major pursing a certificate in Decision Science and a minor in Chinese. She is interested in behavioral economics and how it can be applied to improve general well-being. 


Lucy Greenwald

Lucy (Duke '20) is a Biology major with a minor in Chemistry. She is interested in behavioral science approaches to marketing, infectious disease prevention and treatment, and forensic pathology. 


James Meade

James (Duke '20) is a Chemistry major pursuing a certificate in Decision Sciences. He is interested in how the mechanisms of motivation and decision making can be applied to improve our efficiency, well-being, and health.


Michael Model

Michael (Duke '20) is a Statistical Science major pursuing a minor in Economics and a certificate in Decision Science. He is interested in behavioral economics, neuromarketing and how age and other factors affect financial decision making.


Carmela Guaglianone

Carmela (Duke '21) is considering a major in Neuroscience and Global Health. In high school, she interned in a lab at Arizona State studying stress in the brain.


Leah Burgess

Leah received her bachelor's in psychological science and counseling from Austin Peay State University in 2015. She is currently a project coordinator on a collaborative study between our lab and the Zald Affective Neuroscience Lab at Vanderbilt. She is located in Nashville.

Where are they now?

Wondering what you can do after working in a psychology and neuroscience lab? Just about anything! Students  from our lab go on to post-bacc research positions (RA at MIT Sloan, RA at Harvard Psychology Department, RA at Duke Center for Cognitive Neuroscience), graduate degree programs in psychology (PhD at WashU, PhD at Georgetown), neuroscience (PhD at Washington), political science (PhD at Princeton), computer science (PhD at Brandeis), business (MBA at Yale SOM), medicine (MD at Harvard, MD at UCLA, MD at UChicago), public health (MPH at Yale, MPH at University of New Haven) or even music (MM in opera at Yale School of Music). Many other students and fellows work in tech (BetterWorksCreativeLive, Dropbox, Microsoft), finance (AIG Strategic Planning, Voleon Capital Management), consulting (BCG, Bane, Kingsley AssociatesMcKinsey, Oliver Wyman), marketing (Mark Cuban CompaniesTempo Strategic), or management (McMaster-Carr).
