Mandel is a senior defence scientist and Group Leader of the Thinking, Risk, and Intelligence Group (TRIG) in the Adversarial Intent Section at DRDC Toronto, the human effectiveness centre within Defence Research and Development Canada, a special operating agency of the Canadian Department of National Defence. Dr. Mandel is also Adjunct Professor of Psychology at the University of Toronto. He was Associate Professor of Psychology from 2001-2004 at University of Victoria, Senior Lecturer in Psychology at University of Hertfordshire from 1998-2001, and Social Sciences and Humanities Research Council of Canada Postdoctoral Fellow in the Department of Psychology at Stanford University from 1996-1998. Dr. Mandel's research focuses on descriptive, normative, and prescriptive aspects of human judgment, decision making, thinking, and reasoning. His recent work is particularly concerned with expert judgment in the area of intelligence analysis. Dr. Mandel is also interested in studying the social, political, and psychological bases of collective violence and conflict. Dr. Mandel served as the Canadian representative on the NATO Technical Team of the Human Factors and Medicine Panel's Task Group 140 on Psychosocial, Organisational, and Cultural Aspects of Terrorism from 2006-2009. He is a Fellow of the Society for the Psychological Study of Social Issues (SPSSI), a past Editorial Board member of Analyses of Social Issues and Public Policy and a current member of the Editorial Board of Basic and Applied Social Psychology. He has twice served as an ad-hoc review board member for NIH's Cognition and Perception section, has addressed The National Academies Committee on Behavioral and Social Science Research to Improve Intelligence Analysis for National Security, and The National Academies Committee on Field Evaluation of Behavioral and Cognitive Sciences-Based Methods and Tools for Intelligence and Counter-intelligence. In 2005, Dr. Mandel co-edited The Psychology of Counterfactual Thinking (Routledge) and he recently co-edited Neuroscience of Decision Making (Psychology Press). Dr. Mandel's basic research in cognitive psychology is funded by Discovery Grants (2002-2007, 2007-2012) from the Natural Sciences and Engineering Research Council of Canada (NSERC). He is also the Principal Investigator of a Technology Investment Fund project on warning intelligence and influence processes pertaining to intra- and inter-state conflict (2007-2010) and the Principal Investigator of an Applied Research Program project on understanding and augmenting human capabilities for intelligence analysis (2008-2012). A particularly rewarding non-professional activity for Dr. Mandel was the editing of his mother's memoir A Survivor's Memoir, which was published by the Montreal Institute for Genocide and Human Rights Studies in 2001.
