Katherine McLean, Ph.D., associate professor of criminal justice, is a sociologist and ethnographer whose research explores the intersection between criminal justice and public health. Her research considers how the simultaneous criminalization and medicalization of illicit drug use impact individual identity, community health, and social institutions.

She is particularly interested in "harm reduction" strategies like syringe exchange, and how such programs exist within and adapt to the "war on drugs." Her current research explores how criminal-moral understandings of drug use perpetuate stigma, even as evidence-based interventions proliferate and gain acceptance.

Students in Dr. McLean’s classes can expect an environment that invites diverse forms of participation and hands-on learning. In-class assignments might involve VR headsets and the creation of 360 tours, while podcasting projects and student teaching presentations may replace traditional “final exams.” Dr. McLean endeavors to create opportunities for student voice and choice, and welcomes student suggestions for course materials, topics, and projects. By allowing students to chart their own interest-driven paths, she hopes they will leave class better prepared for their chosen careers.
