My research is in geometry and topology. I am currently working on the following topics:
- bounded cohomology and simplicial volume
- moduli spaces of Higgs bundles and representation varieties
- harmonic maps into symmetric spaces and their degenerations
- geometry of special functions (polylogarithms, hypergeometric functions)
- gauged Gromov-Witten theory
I am a member of the DFG Priority Program Geometry at Infinity.
