Welcome to my homepage!

I am a third year PhD student of Prof. Littelmann in Cologne.

My main areas of research are representation theory and algebraic geometry. I study toric degenerations of varieties that are interesting from a representation theoretic point of view: for example, Grassmannians, flag varieties, or Schubert varieties. I enjoy working with combinatorics arising from various constructions of toric degenerations and want to understand how different approaches are related to each other. My research involves the study of Newton–Okounkov bodies, Khovanskii bases, tropical geometry, and cluster varieties.
