Pete Hatemi is a research fellow at the United States Studies Centre at the University of Sydney and professor of Political Science, Microbiology and Biochemistry at The Pennsylvania State University. He was trained in political science at the University of Nebraska, and in genetic epidemiology at the Queensland Institute of Medical Research (QIMR). He continued his post-doctoral study in Human Genetics, Psychology, and Psychiatry at the Virginia Institute for Psychiatric and Behavioral Genetics (VIPBG) in the Medical College of Virginia. He is primarily interested in advancing the study of the neurobiological mechanisms of social and political behaviors and utilizing advanced methods in genetics, physiology, endocrinology, and neurology in order to better understand human decision making and preferences in complex and dynamic political environments. He also an active member of the Institut for Statskundskab at Syddansk Universitet, VIPBG and the genetic epidemiology lab at QIMR.

Dr. Hatemi's recent work on the genetic, physiological, and endocrinological sources of individual differences in political attitudes, fear dispositions, mate selection, addiction, personality, political violence, and religion has appeared in the American Journal of Political ScienceBehavior GeneticsDemographyEvolution and Human BehaviorJournal of PoliticsPolitical Psychology,Science, and Social Forces among other venues. His recent book, co-edited with Rose McDermott,Man is by Nature a Political Animal at the University of Chicago Press, offers a comprehensive volume that includes applications of evolution, genetics, primatology, neuroscience, and physiology, to understand political preferences.
