Michael Hogg is professor and chair of social psychology at Claremont Graduate University and an honorary professor of psychology at the University of Kent. He is a social psychologist who studies self and social identity, group processes and intergroup relations, and influence and leadership, and is closely associated with social identity theory. He has conducted research on group formation, solidarity, and cohesion; group structure and processes of disintegration, marginalization, and deviance; attitudes, norms, and behavior; communication, language, and identity; leadership and influence; group and identity motivations; and uncertainty and radicalization. Hogg directs the Social Identity Lab, a center for social psychological research on group processes, intergroup relations, and the self-concept. He is also foundation editor-in-chief of Group Processes and Intergroup Relations, an associate editor of The Leadership Quarterly, and a past associate editor of the Journal of Experimental Social Psychology.

Hogg studied psychology at Birmingham University and obtained his PhD from Bristol University. He has taught at Bristol University, Macquarie University, and the University of Melbourne, as well as the University of Queensland. While there, he founded the Center for Research on Group Processes, served as associate dean of research for the Faculty of Social and Behavioral Sciences, and was an Australian Research Council Professorial Fellow. He also taught at Princeton University and has been a visiting professor and scholar at the University of California, Los Angeles; the University of California, Santa Cruz; City University, Hong Kong; the University of California, Santa Barbara; and the Università di Roma Sapienza. He joined the faculty of Claremont Graduate University in 2006.

Hogg is an advisory board member for the department of psychology at Durham University, and serves as a scientific advisory panel member for the Center for Research on Online Political Hostility at Aarhus University in Denmark. He is a former president of the Society of Experimental Social Psychology and is a fellow of the Association for Psychological Science, the Society for Personality and Social Psychology, the Society of Experimental Social Psychology, the Society for the Psychological Study of Social Issues, the Western Psychological Association, and the Academy of the Social Sciences in Australia.

He received the 1989 Early Career Award from the Australian Psychological Society; was awarded (in 2004) an Australian Research Council Professorial Fellowship and a British Academy Visiting Professorship; received the 2010 Carol and Ed Diener Award in Social Psychology, the Society for Personality and Social Psychology’s mid-career award for “outstanding contributions to the fields of personality and social psychology”; and received the International Society of Self and Identity’s 2020 Society for Personality and Social Psychology Distinguished Lifetime Career Award.

His current research programs focus on identity-related influence and leadership processes in public and small group contexts; on the role played by social identity in radicalization, populism, and social disintegration; and in translating uncertainty into orthodoxy and societal extremism. Hogg has published a combination of about 380 articles, chapters, and books on these and other topics in social psychology. His published work has attracted more than 100,000 citations (h-index 125, i10-index 283).
