Research Interests

My research interests include studying the neurobiological mechanisms underlying alcoholism and addiction.  My major area of interest is the neurobiology of ethanol’s stimulus properties.  All drugs of abuse share the common attribute that they produce subjective stimulus effects in humans (e.g., the feeling of “drunkenness” that accompanies alcohol drinking).  These subjective effects contribute to drug taking behavior.  We are presently using behavioral pharmacology and immunohistochemistry techniques to examine the involvement of metabotropic glutamate receptors (mGluRs) in ethanol’s stimulus properties (K01 Award).  Another area of interest is the neurobiology of ethanol reinforcement using animal models of ethanol self-administration.  Using a multidisciplinary approach we are investigating the involvement of mGluRs in ethanol reinforcement and in the motivation to self-administer ethanol.  Together, studying mechanisms involved in ethanol’s stimulus properties and ethanol reinforcement has numerous implications for the development of therapeutic interventions in alcoholism and for identifying factors that influence pathological behavioral processes in addiction, such as drug taking and relapse.
