Research Interests

The common goal of my research is to identify the molecular and cellular mechanisms in the central nervous system involved in the psychoactive and addictive properties of drugs of abuse. In addition to a number of collaborative projects allowing me to investigate drug-induced changes in gene expression on a genomic scale, I have developed independent projects focusing on key presynaptic dopaminergic elements that my play a role in the reward and reinforcing effects of ethanol.
