Welcome!

I am a Ph.D. Candidate at CREST, ENSAE Paris, Institut Polytechnique de Paris under the supervision of Prof. Xavier D’Haultfœuille since September 2019.

My main field of research is Econometrics, with a focus on identification and estimation of nonlinear panel data models. I am particularly interested in the use of high-dimensional statistics and machine learning tools (e.g., unsupervised clustering for grouped fixed effects) to solve such problems.

**I am on the 2022/2023 Academic Job Market, available for interviews.**

I visited the Department of Economics of the University of Chicago in the Winter and Spring of 2022, invited by Prof. Stéphane Bonhomme.

I am co-organizer of the Statistics•Econometrics•Machine-Learning seminar at CREST.
