I am working in the DFGproject "L²Invariants of Quantum Groups" with Thomas Schick. My mathematical interests lie in Lie algebras, algebraic topology, L²invariants in differential geometry and mathematical finance. I defended my dissertation in April 2013. Starting from July 2013 I will be a postdoc at Bonn working with Wolfgang Lück.
Here are the slides of a talk introducing the famous "Göttinger Koffer" on the construction of the regular 65,537gon for the first Night of Science in Göttingen (in German).
