Research Interests

Understanding the etiology and course of alcohol use disorders by combining neuroimaging methods with genetic analyses; DNA methylation in response to long term alcohol use, including the implication of cardiovascular exercise as a protective or reparative factor; neurobiological correlates of craving and response inhibition, and the relationship between incubation of craving and relapse.
