Anthony F. Lemieux, Ph.D., M.A. is the Director of the Global Studies Institute, and Professor of Global Studies and Communication at Georgia State University, where he is also a lead researcher in an interdisciplinary second-century initiative on Trans-Cultural Conflict and Violence. He has extensively studied motivations for terrorism and violent extremism.

Lemieux is the Principal Investigator of the U.S. Department of Defense Minerva Initiative (DOD) supported interdisciplinary, multi-institution, research program on Mobilizing Media which leverages empirically-validated models of health behavior change, persuasion, and communication to provide comprehensive analysis of strategic communication campaigns and propaganda outputs of terrorist groups including magazines, music, images, texts, and videos. This program of research is currently funded through 2020. 

He is also the Principal Investigator of a program on Using Experimental Research to Study the Dynamics of Radicalization and Terrorism, which involves an interdisciplinary and multi-institution team of colleagues involved in creating cutting-edge augmented-reality based experiments to examine the impact of grievance on support for terrorism and non-violent protest. In this broader program of experimental research, his team has collected data from Egypt, Morocco, Jordan, Turkey, Malaysia, and the United States using online data collection methods. This research is supported by the U.S. Department of Homeland Security (DHS) through the National Consortium for the Study of Terrorism & Reponses to Terrorism (START). Recent collaborative work on psychological, communicative and behavioral aspects of cyber security was supported by the National Science Foundation (NSF).

In addition, in a program of research supported by the National Institute of Mental Health (NIMH), Lemieux has developed and evaluated music-based behavioral change interventions in the context of HIV Prevention, HIV treatment adherence, and health behavior change, and has an extensive background on program and intervention development and evaluation.

Lemieux has lectured at a wide range of academic institutions, as well as the United Nations headquarters in New York, the headquarters of the U.S. Central Intelligence Agency, the National Security Agency, the U.S. Department of Homeland Security, the U.S. Transportation Security Administration, the National Counterterrorism Center & Office of the Director of National Intelligence, and the Centers for Disease Control, among others. Lemieux’s extensive record of peer-reviewed publications includes articles in Terrorism and Political Violence, Communication Research, Critical Terrorism Studies, AIDS & Behavior, Journal of Personality & Social Psychology, Dynamics of Asymmetric Conflict, and Health Psychology. He has taught extensively and has served as a subject matter expert on terrorism, radicalization, behavioral screening technologies and innovative survey methods. Lemieux has regularly been featured in National and International media including CNN, MSNBC, Al Jazeera, The Wall Street Journal, Fox, and others, and has a blog at Psychology Today on the motivations and methods of terrorism. Lemieux earned his Ph.D. and M.A. in social psychology at the University of Connecticut and his B.A. in psychology and sociology at Boston College.
