Here is my Curriculum Vitae.

I am member of the Priority Program " Geometry at infinity " funded by the DFG.


My research lies in the field of Global Surface Geometry. I am investigating constrained Willmore tori, i.e., critical points of the Willmore energy with prescribed conformal class, and CMC surfaces (of higher genus) using the Integrable Systems approach, where moduli spaces of flat connections naturally appear.

I am particularly interested in the interplay between Algebraic Geometric data of the surfaces coming from Integrable Systems (e.g., Higgs bundles, spectral curves) and their analytic properties (e.g., non degeneracy and stability) studied in Geometric Analysis.

In my thesis I classified equivariant constrained Willmore tori in the 3-sphere under supervision of Prof. Dr. F. Pedit.
