About me
I am currently a postdoctoral researcher at the
Institute of Algebra, Number Theory and Discrete Mathematics
at Leibniz University Hannover
with a DFG "Eigene Stelle" within the DFG priority programme SPP 2458
"Combinatorial Synergies".
For my earlier positions please see my CV.
My research is in the field of algebraic and geometric combinatorics with connections to commutative algebra, algebraic geometry and algebraic topology. I am particularly interested in the interplay between combinatorial, algebraic and topological invariants of discrete geometric objects like hyperplane arrangements, i.e. finite sets of codimension one subspaces in a finite dimensional vector space, oriented matroids, and reflection groups.
