Hugo Sant'Anna

Assistant Professor of Economics at UAB Collat School of Business. I study how large-scale disruptions — immigration shocks, environmental crises, gender dynamics — reshape labor markets, and I build AI tooling to improve empirical research.

Currently obsessed with difference-in-differences when time-varying covariates carry the identification.
