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