I am a Principal Researcher in the Office of the Chief Economist at Microsoft, and an Assistant Professor in the Department of Economics at Vanderbilt University (on leave).

I am also an Associate Editor for the Journal of Business & Economic Statistics.

I work primarily on Econometrics. My research interests span:

  • Causal inference;
  • Semi- and non-parametric methods;
  • Specification testing.
