My research focuses on identifying the brain mechanisms that modulate neurobiological responses to alcohol. I am interested in understanding how brain neurocircuitry changes after ethanol exposure and how these changes can contribute to the transition from alcohol used to alcohol abuse. I am particularly interested in the roles of neuropeptides on ethanol consumption and how these neuropeptides can be affected by ethanol exposure. Another research approach is to identify the neural mechanisms that modulate the aversive reaction to ethanol and their role in modulating ethanol consumption, with special interest in the brainstem.
My research involves a diverse set of techniques including drinking in the dark (DID) procedures to model binge drinking in mice, operant self-administration procedures, measures of anxiety-like behavior, immunohistochemistry, immunofluorescence, Western Blotting, Cre-inducible chemogenetic tools, Cre-Flox technology and site-direct brain cannulation and viral-vector infusions.
