Research Interests
The focus of my work is on the interplay of inhibitory control deficits (disinhibition) and reward-related processing implicated in substance abuse and addiction specifically, and psychopathology more broadly. To study these transdiagnostic processes, I have an interest in using a variety of methodologies, including interview, self-report, behavioral performance, event-related potentials (ERPs), and structural and functional magnetic resonance imaging (MRI). Additionally, I am interested in the application of advanced quantitative methods facilitating the study of substance abuse. My most recent work shows an interactive effect of neural reward sensitivity to natural rewards and disinhibition predicting severity of substance use disorder symptomatology among community and college adults (blunted natural reward sensitivity x heightened disinhibition -> most severe symptomatology). One important implication of this work is that it provides a method for predicting an individual’s proneness to drug abuse based on how their brain responds to non-drug rewards. My main goal is to understand addiction through a lens that joins research on basic neurobehavioral dispositions with behavioral economic concepts of substance-free reward to decrease the burden of addiction on society.
