I am a postdoc at TU Darmstadt in the research group of Prof. Dr. Jan Bruinier. Previously, I was a PhD student at GU Frankfurt under the supervision of Prof. Dr. Martin Möller.

Research interests

I am working on orthogonal Shimura varieties, with particular interest in their interaction with Siegel modular forms. More precisely, I deal with cones of special cycles, the problem of their polyhedrality, the equidistribution of the irreducible components of such cycles, and the injectivity of the Kudla-Millson theta lift.
