Police organizations, police reform, police decision making, police technology, punishment in an historical context
Professor Willis' interests include police organizational reform, police discretion, police technology, and penal history. With colleagues, his current projects include an examination of the effects of different technologies on police organizations (including body-worn cameras) and an assessment of the quality of police decision-making at the street-level. Along with his co-authors, in 2008 he was awarded the Law and Society Association’s article prize for research that used different theoretical perspectives to explain Compstat’s implementation in three police departments. In 2011, he was the recipient of a George Mason University Teaching Excellence Award.
