I received my PhD in Criminology and Criminal Justice from the University of South Carolina in 2015. Currently, I am an assistant professor in the School of Criminology and Criminal Justice at the University of Nebraska Omaha, where I coordinate our MA program and teach undergraduate and graduate-level classes on policing. My research centers on policing with emphases on procedural justice, legitimacy, and officer-involved shootings. To date, I have published over thirty peer-reviewed journal articles, book chapters, and book reviews related to these and similar topics. I am thrilled to have been selected for the inaugural class of LEADS Academics, because as a criminologist, I believe it is important to convey research findings to people outside of academia – including the police and the general public. I look forward to networking and potentially collaborating with the other LEADS Academics and Scholars to advance policing through rigorous science.
