Since October 2019 I am a postdoc in the working group of Andrew Kresch at the Institute of Mathematics at University of Zurich. Please visit my official website or my personal website.About me

I am a soon finishing PhD student at the Faculty of Mathematics at University of Regensburg. My PhD thesis is on continuous K-theory and its relation to the cohomology of rigid spaces. My advisors are Moritz Kerz and Georg Tamme. I was a member of the DFG GRK 1692 “Curvature, Cycles, and Cohomology” and I was partially supported by the DFG SFB 1085 “Higher Invariants”.My research areas are K-theory and Nonarchimdedean Geometry. Also I am interested in Derived Algebraic Geometry, Motives, and Higher Category Theory.

I wrote my master's thesis “Milnor K-theory of integers of p-adic local fields” and my bachelor's thesis “Serres Problem und der Satz von Quillen-Suslin” (Serre's problem and the Quillen-Suslin theorem) both with Moritz Kerz.
