I am professor at the Université Libre de Bruxelles and fellow of the European Center for Advanced Research in Economics and Statistics (ECARES). My research interests are revealed preference, choice and demand and theoretical economics.

I am member of the Group for the Advancement of Revealed Preference (GARP). I am also co-PI for the EOS funded research project: "Individual Welfare Analysis based on Behavioral Economics" (IWABE).
