I am a PhD Candidate in Economics at HEC Paris. My research interest lie in microeconomic theory, game theory and social networks. I am particularly interested in the role of information and social structures in economic dynamics. Before starting my PhD I worked in consultancy developing mathematical models to solve industry and government problems in Colombia.

I am one of the organizers of the Junior Parisian Game Theory Seminar and the HEC PhD Economics Conference.
