director of several NIH-funded studies during this time. Dr. Dennhardt continues to
work alongside Dr. Murphy in the HABIT lab as a Research Assistant Professor and teaches
several UofM Global courses. Her research interests include addictive behaviors, brief

Education and Training
Dr. James Murphy is a Dunavant Professor of Psychology at the University of Memphis and previously served as the Director of Clinical Training for the Clinical Psychology Doctoral Program. He completed his doctoral degree at Auburn University in 2003 and an Addiction Research Postdoctoral Fellowship at Brown University in 2006. Dr. Murphy’s addiction research has been continuously funded by the National Institute on Health for the past 20 years. He has served as a grant reviewer for several NIH study sections and is an Associate Editor for the journal Psychology of Addictive Behaviors. He is a fellow in APA Division 50 (Society of Addiction Psychology) and Division 28 (Psychopharmacology) and has served as a mentor or co-mentor on over 15 federally funded dissertation or early career development fellowship awards (i.e., NIH F and K awards).
He has published over 220 papers and chapters related to the etiology, prevention, and treatment of alcohol and drug use disorders. Dr. Murphy has developed novel brief intervention approaches that reduce drinking and drug use and tested the effects in a number of randomized clinical trials with young adults, military veterans, and other high-risk populations. His research has helped to establish the efficacy of brief alcohol interventions with a variety of young adult populations, expanded their reach by developing novel computerized and mobile
technology-delivered adaptations, and identified the particular components that are most efficacious. His research also explores novel behavioral economic predictors of substance use severity and treatment outcome, and he has developed novel behavioral economic approaches to enhance addiction treatment.
