About me

I am a PhD student in mathematics at Stockholm University under the supervision of Wushi Goldring. I am also a JSPS fellow at the University of Tokyo under the supervision of Naoki Imai.


My research area lies somewhere between algebraic geometry, number theory and representation theory.  More concretely, I have studied Shimura varieties in positive characteristic, and (moduli spaces of) principal bundles over curves under reductive group schemes.
