John Antonakis (born March 29, 1969) is a professor of organizational behavior at the Faculty of Business and Economics of the University of Lausanne and former editor-in-chief of The Leadership Quarterly.

He was born and raised in South Africa of Greek parents (Paul Antonakis and Irene Bardi) and is Swiss naturalized.

A summary of his work on charisma is available in a recent talk he gave at TEDx[8] and a keynote address at the British Psychological Society meeting [9] He has developed a model with Philippe Jacquart to predict the U.S. presidential elections;[10] their model predicted that Obama would win (refer to Antonakis's YouTube video on the Obama-Romney election race[11]).

Antonakis has written broadly on topics germane to organizational behavior, including on leadership, social cognition, individual differences and methodology (psychometrics and applied econometrics).

[19] He has also shown that, because of endogeneity issues, much of the research done in management and applied psychology is devoid of causal interpretation.
