I am a psychiatrist and neuroscientist with an interest in understanding the neural basis of behavior. My lab aims to determine the neural circuitry underlying stress-induced psychiatric symptoms and why different individuals prove susceptible or resilient. We study the neural underpinnings of reward processing, motivation, cognition and social behavior to ask how stress disrupts these neural circuit computations. To do so, we use in vivo recordings and optogenetic circuit modulations of long-range circuits of mice as they undergo stress and engage in cognitive, social, and rewarding behavior. I am particularly interested in how dynamic communication in these pathways differs between susceptible and resilient individuals as well as between males and females.
