I am an Associate Professor in the School of Criminology and Criminal Justice at the University of Nebraska Omaha. I coordinate our MA program and teach undergraduate and graduate-level classes on policing. I’m also a Co-Director of the VIPR Lab. My research centers on policing with emphases on procedural justice, legitimacy, and police shootings (view my CV).
Welcome to my personal website, where you can download my latest publications as well as conference presentations and invited talks. I also post teaching materials, and occasionally, I blog about stuff. Contact me if you have any questions!
