I am an economist with research interests in the intersection between international economics, macro-finance, and public economics. In particular, my work focuses on understanding the role of financial frictions and heterogeneity on the macroeconomy during financial crises.
My professional experience is in central banking and the private financial industry. I'm currently working at the Financial and Macroeconomic Stability Studies Section of the Federal Reserve Board. Before moving to Washington D.C., I worked as a Quantitative Researcher at Citadel in Greenwich and as an Economist at the Central Bank of Mexico.
