Anatomy and Neurobiology
Education and Training
I graduated from University of Maryland, College Park with an undergraduate degree in Biology. I completed my PhD at University of Maryland School of Medicine, working with Geoffrey Schoenbaum to study the role of amygdala neural activity in attention and associative learning processes. As a postdoc in the laboratory of Yavin Shaham at the National Institute on Drug Abuse (NIDA), I used an optogenetic approach to examine the role of medial prefrontal cortex in relapse to palatable food seeking. As an Early Independent Scientist at NIDA I 1) examined the validity of the food relapse model and 2) established a research program aimed at exploring the neural correlates and brain reward mechanisms underlying individual differences in addiction vulnerability. I joined Anatomy and Neurobiology in September of 2015.

Behavioral and Systems Neuroscience aimed at elucidating the brain mechanisms underlying individual differences in reward learning, motivation, addiction vulnerability and neuropsychiatric disorders.
We study the brain mechanisms underlying individual differences in natural reward learning, motivation, and behavioral flexibility. We combine classic and modern techniques to examine real-time neural activity in awake, behaving rats as they perform reward learning tasks. We manipulate neural activity to demonstrate a causal role for specific brain circuitry in driving motivated and flexible behaviors. We examine the possibility that competing brain systems drive individual differences in cognitive strategies used for reward learning, with the ultimate goal of understanding vulnerability to addiction and neuropsychiatric disease.
