I am a postdoc in the working group of Prof. Peter Littelmann in Cologne working in the project C3 Momentum polytopes, string polytopes and generalizations of the CRC/TRR 191 Symplectic Structures in Geometry, Algebra and Dynamics. I defended my PhD thesis in October 2014.

Research: My research focuses around the theory of crystal graphs, an important tool in the study of representation of complex algebraic groups. This theory has a lot of – natural and surprising – connections to polyhedral and tropical geometry, algebraic geometry, combinatorics and homological algebra. The mathematical problems I enjoy the most are the ones building bridges between different areas with a particular stress on explicit formulas and computations. Here my list of publications and preprints:
