My research focuses on learning by individuals and organizations. Several of my papers explain how individuals might develop and maintain inaccurate beliefs because they rely on the biased samples of information they obtain from their experiences. The information used for learning may be biased because more information is available about alternatives that decision makers believe to be good and thus sample again, whereas less information is available about alternatives that decision makers believe to be poor and thus avoid. In addition, the information to which individuals have access also depends on the opportunities the social context provides them with for learning about alternatives they might otherwise avoid.

In related projects on the dynamics of social processes, I have examined the development of technological trajectories, the evolution of cultural tastes and their consequences for organizational viability, and dynamics of organizational failure.

My research has been published in top scientific journals such as Psychological Review, the Proceedings of the National Academy of Science of the USA (PNAS), Cognition, Behavioral and Brain Sciences, Organization Science, Management Science and Administrative Science Quarterly. Popular accounts have appeared in the New York Times, the Times (London), WSJ.com, FT.com, USA Today, ABCNews.com, Focus and other in-print and online periodicals. I have taught graduate courses at INSEAD, London Business School, the University of Lugano, the Barcelona Graduate School of Economics and the Barcelona School of Management.
