I am a Quantitative Researcher at Two Sigma in New York. In 2020-2022, I was a Goldstine Fellow at IBM Research in New York. In 2020, I completed my PhD at Princeton University under the supervision of Amir Ali Ahmadi. Before joining Princeton, I graduated from Ecole Polytechnique.
I am broadly interested in Polynomial Optimization, Dynamical Systems & Control, and Machine Learning. You can learn more about my work by having a look at my papers. In my spare time, I make Machine Learning and Optimization videos with a strong emphasis on building intuition with visual explanations.
