Matthew Nock is a Professor of Psychology at Harvard University.

Matt joined the faculty of Harvard University in 2003 and has been there ever since. While an undergraduate, Matt became very interested in the question of why people do things to intentionally harm themselves, and he has been conducting research aimed at answering this question ever since. His research is multidisciplinary in nature and uses a range of methodological approaches (e.g., epidemiologic surveys, laboratory-based experiments, and clinic-based studies) to better understand how these behaviors develop, how to predict them, and how to prevent their occurrence. He has received multiple teaching awards at Harvard and also four early career awards recognizing his research, and in 2011, he was named a MacArthur Fellow.
