I am a postdoc at Utrecht University in the topology group. Form July 2025 onwards, I will be a postdoc at University of Toronto. 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. 

My name is pronounced "yo-seh-FEEN KEUI-per", with eui as in the French “fauteuil”, or alternatively, a Scottish ou.
