I am a Bernoulli Instructor at EPFL. Here is my CV.

My main research interests are in number theory and its interactions with surrounding fields.

I was a postdoc at Stanford (2023 to 2025) and at IAS (2022 to 2023). I received my Ph.D. from Caltech in 2022, advised by Maksym Radziwiłł. Before that, I received an A.B. from Princeton in 2018.
