Finn Wiersig

I am a Peng Tsu Ann Assistant Professor at the National University of Singapore.

I am on the job market this year. Here is my CV (29 Sep 2026).

My research is on p-adic geometric representation theory, p-adic Hodge theory, and p-adic differential equations.

I did my PhD at the University of Oxford, supervised by Prof. Konstantin Ardakov and Prof. Kobi Kremnitzer.
