Reuma Gadassi-Polack, P.h.D


Reuma received her doctoral degree in Psychology from Bar-Ilan University, and her M.A. in Educational and Clinical Child Psychology from the Hebrew University of Jerusalem. Reuma’s research focuses on the affective and interpersonal aspects of depression and personality disorders. She is currently working on projects investigating role of emotion regulation in the development of depression and other disorders. To approach these questions she uses various methods, including cognitive tasks, experience-sampling methods, and brain imaging.

Jessica Mollick, Ph.D.


Jessica is interested in the brain mechanisms involved in learning and decision making, and the role that neuromodulatory systems such as dopamine play in these tasks. Her research focuses on computational neural network models of the basal ganglia, amygdala and dopamine system, with a particular focus on expanding those models to look at the role of dopamine and the basal ganglia in negative valence learning and understanding the brain mechanisms that drive prediction errors for worse than expected outcomes. She has applied these models to a variety of learning tasks. Her empirical research focuses on fMRI, using a conditioned inhibition experiment with juice rewards that draws on worse than expected prediction errors, and involves applying temporal-differences learning and neural network models to this experiment, as well as a pain learning task, to assess the fit of these different models to fMRI data in dopaminergic and subcortical regions. She is interested in comparing the fit of different models with empirical data, and looking at how evaluation of reward and punishment outcomes relates to addictive behaviors.

Maria Christina Crouch


Maria Christina Crouch (Deg Hit’an and Coahuiltecan), PhD, is a clinical-community psychologist and an NIAAA F32 postdoctoral research fellow at Yale University. Her program of research is focused on the intersection of trauma-informed care, evidence-based practices, and practice-based evidence (Indigenous approaches) to address alcohol and drug issues, trauma, and related health impacts of social determinants among American Indian and Alaska Native communities from a cultural, strengths-based approach.
