I am an Associate Professor of Economics at Emory University.

My research interests lie in Applied Econometrics, particularly in Causal Inference. In the last few years, I have focused on better understanding and improving Difference-in-Differences methods.

I am currently an Associate Editor for the Journal of Econometrics and for the Journal of Business & Economic Statistics.
