PhD candidate in Economics
Universidad Carlos III de Madrid

I am a macroeconomist studying firm dynamics, competition, and resource reallocation, and how they shape aggregate productivity and long-run growth. I also work on impact evaluation, using experiments and quasi-experiments.

I will be on the academic job market in 2027–2028.
