About
I am an Assistant Professor of Finance at the University of Florida. My research studies how machine learning and large language models reshape financial markets: return predictability, textual analysis of disclosures, and the cross-section of expected returns.
I hold a Ph.D. in Finance from the Wharton School, University of Pennsylvania, and a B.A. and M.A. in Economics and Financial Management from ITAM. Before joining the University of Florida I was an Assistant Professor of Finance at BI Norwegian Business School.
