Currently, I am a postdoc at Utrecht University in the topology group. I obtained my PhD in June 2024 at Stockholm University, under the watchful eye of Dan Petersen. 

I am interested in homotopy theory, algebraic geometry and (higher) categories. More specifically, my current research interests include cohomology theories of algebraic varieties, in particular six-functor formalisms; and algebraic K-theory, in particular scissors congruence and the K-theory spectrum of varieties.

Here is my CV.
