My research involves the neuroimaging of the human brain’s reward system (using both PET and functional MRI), and motivated behavior for natural rewards (such as food) and drugs of abuse.  The work in my lab is broadly targeted to understand the brain and genetic vulnerabilities that may predispose individuals to disorders such as alcoholism and obesity.
