Graduate Student Postdoctoral Fellow

Period of Service

March 1995 - June 2000

After the NRLC

Jim went on to complete a Postdoctoral Research Fellowship at the Laboratory of Clinical Translational Studies at the National Institute of Alcohol Abuse and Alcoholism (NIAAA), in Bethesda, Maryland. At, NIAAA, Jim expanded his scope of impulsivity research to include structural and functional magnetic resonance imaging. After completing his fellowship, he assumed a position as Program Official in the Division of Clinical Neuroscience and Behavioral Research at the National Institute on Drug Abuse (NIDA). In this position, Jim is working to expand a NIDA-funded portfolio of extramural research on neuroimaging, impulsivity/incentive processing, and substance abuse. His additional activities include organizing workshops and symposia to bring cutting edge imaging technologies to the study of deviant brain function as a risk factor for (or consequence of) substance abuse.
