about me

I’m a PhD candidate at UC Berkeley, in the Business and Public Policy group at the Haas School of Business, and the ACES Dissertation Fellow. I have a BA in Economics from Universidad de los Andes (Colombia).

In the Fall of 2025 I will join the Vancouver School of Economics at the University of British Columbia as an Assistant Professor, after spending one year at Princeton University as a Postdoctoral Research Associate at the Research Program in Development Economics.

My research interests are in political economy, development economics and behavioral economics.
