Floris Vermeulen

I'm currently a postdoc in Paris at ENS working with Silvain Rideau-Kikuchi. Before that, I was a postdoc in Münster working with Franziska Jahnke. Even before, I was a PhD student at the algebra section at KU Leuven under supervision of Raf Cluckers. I am broadly interested in the following topics:

Tame non-Archimedean geometry, Hensel minimality and motivic integration.
Rational and integral points on varieties, curves over finite fields, and point-counting.
The geometry of curves, scrollar invariants, and syzygies.
