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.

Recent Updates:


Jonathan Roth, Alyssa Bilinski, John Poe and I have been working on a reviw of recent DiD advances. We are very happy to post the first draft of our paper What's Trending in Difference-in-Differences? A Synthesis of the Recent Econometrics Literature". We tried to be practical and provide concrete advices for applied researchers. Happy to take questions/comments!

Jonathan Roth and I have been working on a paper that characterizes when DiD estimators that rely on a parallel-trends assumption are insensitive/robust to functional form restrictions. Link to our paper is here. Let us know what you think!

Since I routinely get asked about/whether the problems associated with event-study specifications based on TWFE linear regression models are "real", Brant and I wrote this post using a simple simulated DGP to show how much these specifications can be unreliable. Check it out!
