Curriculum Vitae

My research brings econometric theory to questions of practical importance for empirical researchers. My work spans causal inference with panel data, treatment-effect heterogeneity, and semiparametric efficiency—understanding how to make the most of the information available in the data and the assumptions we are willing to make.

I have developed methods for difference-in-differences with multiple time periods, doubly robust estimation, and treatments that vary in timing or intensity, alongside software that helps researchers put these methods into practice. Explore my research.
