Gaël Le Mens is Professor at Universitat Pompeu Fabra and Affiliated Professor of the Barcelona GSE. Professor Le Mens's research focuses on how the social environment and learning processes affect inference, judgment and valuation. His current theoretical focus is on developing models of the influence of categories on inference and valuation, and models of the dynamics of collective valuation (such as online review scores). Professor Le Mens tests the predictions of his models using a variety of methods, such as the analysis of large datasets of online reviews, and a combination of online and laboratory experiments. 

His research has been published in top scientific journals such as Psychological Review, the Proceedings of the National Academy of Science of the USA (PNAS), Psychological Science, Cognition, Organization Science, Management Science and Administrative Science Quarterly. He has taught graduate courses at INSEAD and London Business School.
