Research Focus

Neurobiology of Drug and Alcohol Addiction

Work in our laboratory is concerned with the neurobiological basis of abnormal behavioral and brain functions relevant to human psychopathology with emphasis on the neural control of motivation and reinforcement. The majority of this work is directed at the understanding of the neuropharmcological, neurocircuitry, and molecular basis of drug and alcohol addiction including mechanisms that lead to the development of dependence and withdrawal states, drug craving, relapse as well as impairment in memory and cognitive function.
