My research focuses on understanding the neural correlates of reward and aversion and how they play a role in modulating appetitive and consummatory behavior for natural rewards and drugs of abuse. To this end, I am employing electrophysiological and behavioral techniques in rats to determine the brain mechanisms mediating appetitive behavior driving intake of highly palatable high fat/sugar food, as well as ethanol. Specifically, I am interested in determining the role of opioid signaling in the nucleus accumbens (NAcc), an important node in the reward pathway, in normal feeding and binge eating behavior. Another area of focus is the brain circuitry regulating ethanol intake, with a goal of determining the role of the lateral habenula (LHb), a crucial area in which aversive stimuli are encoded, in regulating voluntary ethanol consumption during early and late stage of alcohol abuse.
