Dr. Hamm Promoted to Full Professor

Dr. Joe Hamm has been promoted to Full Professor in the School of Criminal Justice at Michigan State University.

Dr. Hamm joined the School in 2014 as an Assistant Professor with a joint appointment in MSU’s Environmental Science and Policy Program, and was promoted to Associate Professor in 2020. Stepping into the rank of Full Professor is a reflection of Dr. Hamm’s sustained contribution to the fields of Criminal Justice and Public Policy.

Dr. Hamm earned his PhD in Psychology from the University of Nebraska-Lincoln, where he completed specializations in Law-Psychology and Quantitative Methods. This established the foundation for Dr. Hamm’s research on Trust and Vulnerability as they relate to the relationship between Government and Society.

At MSU, Dr. Hamm leads the Teaching, Researching, and Understanding the Social Science of Trust (TRUSST) Lab at Michigan State University, and has worked with a variety of interdisciplinary teams to secure over $10million in research funding. Dr. Hamm has authored nearly 50 peer-reviewed publications, 9 book chapters, and co-edited the Handbook on Trust in Public Governance. His scholarly contributions have advanced the understanding of legitimacy and trust in society.

Dr. Hamm also serves as Editor-in-Chief of the Journal of Trust Research, and serves on the Editorial Boards for Justice Quarterly, Law and Human Behavior, and Psychology, Public Policy, and the Law.  

“I am truly humbled to think about the army of faculty, students, research participants, and other collaborators who invested so much of their time and effort into the various collaborations on which I’ve built my career. In particular, the School of Criminal Justice has been an incredibly supportive intellectual home that allowed me to do the work that I care deeply about, and I am eternally grateful to everyone whose support made it happen, directly or indirectly.”

Congratulations, Dr. Hamm. Your promotion is well earned and well deserved!
