Joe Hamm is Assistant Professor of Criminal Justice and Environmental Science at Michigan State University. A psychologist by training, his work lies at the nexus of government and the public where he investigates what trust is, how best to appropriately measure it, and its connection to "outcomes" like cooperation and compliance. Joe’s work spans a number of governmental contexts, seeking to use research on trust in trustees like the police, courts, water infrastructure managers, natural resource authorities, and a variety of state and federal entities to develop a cross-boundary social science of trust.

Joe works closely with a variety of criminal justice and environmental organizations, and serves on the editorial boards of the Journal of Trust Research and Psychology, Public Policy, and the Law. His teaching responsibilities include CJ 905 (Law and Society), CJ 908 (The Cross-Boundary Social Science of Trust in the Institutional Context), and ESP 804 (Environmental Applications and Analysis). Joe also supervises the School of Criminal Justice’s doctoral traineeship in the State Courts and Society.
