Dr. Adam Prus is a professor and head of psychology at Northern Michigan University in Marquette, Michigan. He earned his PhD in psychology from Virginia Commonwealth University and a master's degree in psychology from Western Michigan University. While in graduate school, Prus also worked as a research technician at a large pharmaceutical company, where he screened central nervous system drugs using various biological assays. After earning his PhD, Dr. Prus investigated experimental antipsychotic drugs as a postdoctoral fellow in the Psychopharmacology Division of the Department of Psychiatry at Vanderbilt University. Dr. Prus has published numerous original studies on psychoactive drugs, including studies funded by the National Institute on Mental Illness and private foundations. At NMU, he directs the Neuropsychopharmacology Laboratory, where he enjoys mentoring undergraduate and graduate students and spends too much time fixing lab equipment. When he is not teaching, training students, writing books or conducting research, Dr. Prus spends time with his wife and two children, and together they enjoy outdoor activities in Michigan's Upper Peninsula, where NMU is located.
