Dr. Arielle Baskin-Sommers (pronouns: she/her/hers) is a licensed clinical psychologist and Associate Professor (on Term) at Yale University. She received her Sc.B. from Brown University (2007), a Ph.D. from the University of Wisconsin-Madison (2013), and completed her pre-doctoral internship and fellowship at McLean Hospital/Harvard Medical School. Substantively, her research is concentrated on understanding individual differences in cognitive and affective processes as they relate to vulnerability for disinhibitory (impulsive, antisocial) psychopathology. Methodologically, she is interested in integrating a wide range of techniques and technologies to explore this issue. Overall, her professional career goals are based on a desire to develop both innovative theory and research in service of increasing the efficacy of clinical intervention for disinhibited behaviors.

Curriculum Vitae

Post-Docs and Graduate Students

Cortney Simmons received her B.A. in Psychology from Rice University and her Ph.D. in Psychological Science from the University of California-Irvine. She broadly focuses on juvenile delinquency and adolescent development within the context of the juvenile justice system. Cortney’s research integrates developmental psychology, criminology, psychobiology, and quantitative modeling to examine how individual and contextual factors contribute to risk taking and antisocial behavior. She also examines the juvenile justice system as a developmental context that affects adolescents’ educational achievement, wellbeing, and behavior.


Curriculum Vitae

Grace Brennan received her B.S. in Psychology and German Studies from the College of William and Mary in 2012. Before joining the lab, she conducted neuroimaging research on alcohol use disorders at the National Institute on Alcohol Abuse and Alcoholism. She is interested in using multiple methodologies to identify the cognitive, affective, and neural mechanisms underlying substance misuse and aggression, and in translating research findings into mechanism-specific clinical interventions. She is particularly interested in using computational modeling techniques to specify the cognitive mechanisms that underlie chronic aggression. 

Curriculum Vitae

Allison Stuppy received her B.A. in Psychology from Stanford University in 2011. Before joining the Yale MoD lab, Allison gained clinical research experience implementing a post-deployment intervention for Army soldiers through the military medical school’s Center for the Study of Traumatic Stress.  More recently, she conducted clinical and lab-based work exploring intertemporal choice, impulsivity, and addiction, at the University of Maryland Center for Addictions, Personality, and Emotion Research in College Park. Allison is interested in understanding the complex association between reward and cognitive processing and its implications for substance misuse. 


Curriculum Vitae

Scott Tillem received his B.A. from Case Western Reserve University in 2013 where he triple majored in Psychology, Cognitive Science, and Sociology.  Prior to pursuing his graduate studies at Yale, Scott worked as a research associate at the Lieber Institute for Brain Development, part of Johns Hopkins Medicine, where he analyzed fMRI data related to reward processing and social cognition. Scott’s primary research interests lie in understanding the neural underpinnings of psychopathy. He is interested in applying different analytic approaches to EEG and MRI data so as to develop a greater understanding of the neural networks contributing to the disinhibited behavior of psychopathic individuals. 

Curriculum Vitae

Suzanne (Suzy) Estrada received her B.S. in Psychology and B.A. in Spanish from Yale University in 2016. Prior to her graduate studies, she worked at the MoD Lab as an undergraduate and post-baccalaureate research fellow and conducted research on social decision-making in individuals who engage in antisocial behavior. Suzy is interested in identifying and specifying basic mechanisms of learning, their relationship to trauma (e.g., childhood maltreatment, exposure to community violence), and their implications for understanding antisocial behavior.


Curriculum Vitae

Ariel Chang received her B.A. in Psychology from the University of Chicago in 2015. Prior to joining the MoD lab, she worked as a research fellow in the McPartland Lab utilizing EEG and eye tracking to study social cognition in individuals with autism spectrum disorder. She is interested in integrating multiple methodologies to investigate how social cognitive factors may differ in people from disadvantaged backgrounds and affect engagement in antisocial behavior.
