About

I am a postdoctoral researcher École Normale Supérieure (ENS) - PSL and Laboratoire Lattice, starting from May 2025. I am interested in a wide range of topics concerning LLMs, especially their societal impact. Before the rise of LLMs, my focus was on computational social science and survey methodology, which I still maintain some interest in.

I took the one less traveled by,
And that has made all the difference.
