I am a postdoc in the Topologie Lehrstuhl at Ruhr Universität in Bochum, and my mentor is Gerd Laures. I have research interests in algebraic topology, geometric representation theory and mathematical physics, and my work is centered on equivariant elliptic cohomology.

My PhD supervisor was Nora Ganter
