Andreas Ott
DFG research fellow in the Differential Geometry Group at Heidelberg University

Research

My research is in geometry and topology. I am currently working on bounded cohomology, simplicial volume and polylogarithms, moduli spaces of Higgs bundles and representation varieties, harmonic maps and pleated surfaces, and gauged Gromov-Witten theory.
I am a member of the DFG Priority Program Geometry at Infinity, with the project Invariants and boundaries of spaces.
