Dr. Shahan received his Ph.D. from West Virginia University. Following postdoctoral and research positions at the University of Vermont and the University of New Hampshire, he currently serves as professor and chair of the Experimental and Applied Psychological Science Graduate Program in the Department of Psychology at Utah State University. Across his career, Dr. Shahan has made impressive basic research contributions to a number of critical areas in behavior analysis, including conditioned reinforcement, quantitative analysis of choice and resistance to change, resurgence and drug relapse, information theory, and clinical applications of behavioral momentum theory. This empirical work has been supported by more than $7 million from the NIH and accompanied by influential review papers focused on highly original integrations across these research interests. Dr. Shahan has also made extensive service contributions to the field, including as associate editor of JEAB, special editor of Behavioural Processes, president of SQAB, and member of the SEAB board. His representation of behavior analysis as member and chair of the NIH’s Biobehavioral Regulation, Learning, and Ethology study section is especially noteworthy.
