I will be joining the Federal Reserve Board in the Financial and Macroeconomic Stability Studies section next Fall.

I received my Ph.D. and M.A. in Economics from The University of Pennsylvania in 2021. I also hold an M.A. in Economic Theory and B.A. in Economics from ITAM in Mexico City.  Before moving to Washington D.C., I worked as a Quantitative Researcher at Citadel in Greenwich and as an Economist at the Bank of Mexico. My research focuses on international economics, macro-finance, and public economics.
