I am a professor of psychology at Iowa State University and a faculty member in the psychology and law group. I run a joint psychology and law lab with my colleague, Dr. Max Guyll. I received my Ph.D. in social psychology from Rutgers University under the direction of Dr. Lee Jussim. The substantive nature of my research examines how social influence processes alter people's behavior with a variety of socially important contexts. My main line of research examines why criminal suspects confess to crimes when subjected to police pressure. My work in this area emphasizes the idea that police interrogation exploits suspects' psychological vulnerabilities in ways that can make them highly susceptible to misinformation, short-sighted thinking, false memories, and false confession. I also have interests in forensic analysis, especially the forensic analysis of fired cartridge cases. My research has been funded by the National Science Foundation, the American Psychological Foundation, and the Society for the Psychological Study of Social Issues. I am a fellow of the Society of Experimental Social Psychology and the Association for Psychological Science and serve on the Editorial Board for Law and Human Behavior. I teach courses in research methods and psychology and law.
