Postdoctoral Fellows


Jeroen van Baar

Jeroen obtained his BSc and MSc at Utrecht University in the Netherlands. During his masters, he spent seven months training with Catherine Tallon-Baudry in Paris, after which he moved back to Holland to pursue his PhD with Alan Sanfey at the Donders Institute. In his doctoral studies, Jeroen worked on the psychological and neural underpinnings of moral decision-making. He combines economics-based computational modeling with functional MRI to study inter-subject variation in the neural processing of moral decisions. In 2014, Jeroen published a popular science book on the psychology of overachieving, and he has done some related science communication projects (TEDx talk here). Twitter: @jeroen_van_baar.

Graduate Students

Joseph Heffner  |  ContactCV

Joey received a B.S. in Psychology and a B. A. in Philosophy from the University of North Carolina at Chapel Hill in 2013. He served as project manager for Dr. Walter Sinnott-Armstrong at Duke University for three years investigating the effects of implicit moral attitudes. Joey's current research investigates human social cognition and decision-making, focusing particularly on how people respond to fairness violations. He utilizes behavioral economics and social psychology approaches to explore questions like: In what contexts do people value punishment over non-punitive alternatives? How do people learn the value of prosocial actions in ambiguous and noisy environments? What aspects of the environment influence decisions to compete or cooperate?


Amrita Lamba  |  ContactCV

Amrita received a B.S. in Psychology from the University of Toronto in 2014 and an M.A. in Psychology from the College of William & Mary in 2017. Prior to starting at Brown, Amrita was a member of Wil Cunningham's Computational Affective Neuroscience lab and Joanna Schug's Cross-Cultural Cognition lab. Amrita is interested in examining socio-emotional decision-making and learning using the methodological rigor of computational modeling and neural network systems. She is also interested in using Bayesian and reinforcement learning models as a framework for modeling the cognitive processes associated with moral decision-making. She is co-mentored by Michael Frank.

Willy Lee | Contact

Willy received a B.A. in Economics and a B.A. in Psychology from Brown University in 2018, and is currently a fifth-year Master's student. He is interested in the role of "self and other" perceptions on conformity and moral judgments, as well as the processes/mechanisms involved in different moral decision-making contexts.

Jae-Young Son  |  ContactCV,  Web

Jae is a first-year Ph.D. student interested in how people use social and affective information to inform decision-making. Prior to grad school, Jae worked in Jamil Zaki and Oriel FeldmanHall's labs. When not thinking about science, Jae enjoys singing at unreasonably loud volumes, reading pretentious existentialist philosophy, and going on spontaneous long-distance bike rides and hikes.

Lab Manager


Logan Bickel | Contact

Logan received a B.A. in Cognitive Science from the University of Michigan. While there, he was an honors student in Stephanie Preston’s Ecological Neuroscience Lab and the lab manager for Rick Lewis’s Lab for Computational Cognitive Science. He additionally held a summer research position in Daniel Gilbert’s lab at Harvard. Logan is generally interested in the role of emotion and context in (moral and social) decision making. Particular interests include the valuation of one’s self relative to others, and circumstances involving blame and punishment. Logan also enjoys skateboarding and short films.

Undergraduate Research Assistants


Danai Benopoulou

Danai is a sophomore pursuing a double concentration in Psychology and Economics at Brown University. She is interested in using her studies in each of these fields to better understand empathy and pro-social behavior in modern societies, many of which have experienced increased hostility and prejudice. Her decision to double-concentrate stems also from her interest in studying how emotions affect everyday decision-making, social interactions, and judgments.

Eric Ingram

Eric is a sophomore pursuing a concentration in psychology at Brown University. He is interested in studying the neural mechanisms behind cognitive decision making, and intends to pursue a career in mental health and psychiatric disorders. Aside from academics, Eric is a sprinter on the Brown Track and Field team and serves as an academic tutor for athletes.


Haoxue Fan

Haoxue is a student intern in Dr. FeldmanHall’s lab. She is a senior majoring in Psychology and minoring in Economics at Peking University. Haoxue is generally interested in the neural mechanisms of social decision-making, how people take others’ opinions into consideration, and the difference between making decisions for self and others. Outside the lab, she enjoys playing badminton, watching fun TV series, and learning new languages (just the alphabets).

Marlon Sherman

Marlon is a sophomore concentrating in Behavioral Decision Sciences at Brown University. He is interested in studying how Economics and Game Theory relate to Social Decision Making. He also is interested in Political Theory and is considering pursuing Decision Sciences in the realm of Law. For fun, Marlon spends his time singing a cappella with The Alef Beats, serving as a Meiklejohn Peer Advisor for first-year students, and watching classic movies.


Nancy Nkoudou

Nancy is a sophomore concentrating in Cognitive Neuroscience. She is interested in investigating the neural mechanisms involved in moral decision-making, and specifically how these processes are divergent in neural-atypical populations. Nancy's other commitments include singing in Brown's gospel choir Harmonizing Grace,  as well as producing podcasts through the WBRU radio station.

Nina Zhao

Nina is a junior double-concentrating in psychology and economics at Brown University. She is interested in behavioral economics, particularly how people evaluate risks and uncertainties. She is also interested in investigating the influence of social factors on the decision-making of individuals. Outside the lab, Nina is a member of Brown Taekwondo club.

Grace Deng

Grace is a sophomore double concentrating in Psychology and Applied Math. She is interested in human social behaviors, especially the subtle relationship between self-interest and moral behaviors. She is also a huge fan of novels and movies. 

Yutong Liu

Yutong is a junior concentrating in Economics and Psychology. She is interested in behavioral economics and the factors that affect social decision-making. Moreover, she is interested in how social biases can affect people's opinions and actions toward others. Outside of the lab, Yutong enjoys basketball, hiking, and golden retrievers.
