About me
I am a postdoc in the working group of
Alexander Schmidt
at the
Mathematical Institute
at the
Faculty of Mathematics and Computer Science
at the
University of Heidelberg.
Furthermore, I am a member of
CRC326 - GAUS: "Geometry and Arithmetic of Uniformizing Structures".
My research areas are K-theory and Nonarchimdedean Geometry.
During the academic year 2019/20 I was a postdoc in the working group of
Andrew Kresch at the
Institute of Mathematics at the
University of Zurich
and financed by the Swiss National Science Foundation.
Until September 2019 I was a PhD student at the
Faculty of Mathematics at the
University of Regensburg.
My PhD thesis is about continuous K-theory and its relation to the cohomology of rigid spaces.
My advisors were
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”.
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.
