Iser (Willie) G. DeLeon earned his Ph.D. at the University of Florida in 1997, and then became a faculty member at the Johns Hopkins University School of Medicine, where he served as the Director of Research Development at the Kennedy Krieger Institute. He returned to his alma mater in 2014, where he is now professor of psychology. Dr. DeLeon has earned a national reputation as a scholar, researcher, and leader in the field of applied behavior analysis. His work serves as a model for the bidirectional transfer between basic and applied research. One significant line of inquiry focuses on the development of strategies to identify effective reinforcers and to understand the range of contextual variables that moderate their efficacy over time in persons with intellectual disabilities and in typically developing adults. His work is notable for its use of concepts derived from behavioral economics, behavioral momentum, and other conceptual models as they apply to behavior analytic interventions. In addition to his impressive research and scholarly contributions, Dr. DeLeon has served on the editorial boards of a number of behavior analysis journals, including as associate editor of the Journal of Applied Behavior Analysis and editor of translational research for the Journal of the Experimental Analysis of Behavior. He has also served as a member of the Board of Directors of the Society for the Experimental Analysis of Behavior and president of the Board of Directors for the Behavior Analyst Certification Board.
