I am currently a member of the BIREP Representation Theory group at Bielefeld University. My position is supported by the Alexander von Humbolt Stiftung/Foundation in the framework of an Alexander von Humbolt Professorship endowed by the Federal Ministry of Education and Research.
Previously I was supported by the Collaborative Research Center CRC701 Spectral Structures and Topological Methods in Mathematics.
Before that I was a lecturer in the School of Mathematics at the University of Leeds.

My research centres around the representation theory of finitedimensional algebras, together with their connections to various other fields such as algebraic geometry, Lie theory and quantum groups, and combinatorics and cluster algebras.
I have also supervised two Ph.D. students
Stefan Wolf, Thesis
The Hall algebra and the composition monoid
Julia Sauter, Thesis Springer theory and the geometry of quiver flag varieties
RingelHall algebras These are unfinished notes from a graduate course on RingelHall algebras. We start with hereditary algebras, cover the basic theory of RingelHall algebras and Green's Formula, prove necessary results about generalised KacMoody Lie algebras and their quantised enveloping algebras, and finally prove Kac's Theorem on the dimension vectors of indecomposable modules using character formulae.
