I don't trust mathematicians with beautiful websites


Me! (a few years ago)

email: martioller (dot) math (at) gmail (dot) com

Starting in September 2026, I am a postdoc at Charles University, Prague. My mentor is Vita Kala.

Before that, in 2022-2026 I was a PhD student at the University of Cambridge under the supervision of Jack Thorne.

I am interested in number theory and arithmetic geometry, and more specifically arithmetic statistics.
