About me

Since October 2022 I am a postdoc in the research group of Prof. Duc Viet Vu at the University of Cologne. Before that, I was a postdoc in the research group of Prof. Daniel Greb at the Universität Duisburg-Essen. I graduated in the Graduiertenkolleg Cohomological Methods in Geometry at the University of Freiburg, supervised by Prof. Stefan Kebekus. The main field of my research interests is complex algebraic geometry, in particular birational geometry in the philosophy of the minimal model program. Currently I am working on the deformation theory of families of irreducible holomorphic symplectic manifolds, Lagrangian fibrations of singular holomorphic symplectic varieties and the question when a Kähler manifold admits an algebraic approximation.
