Bio
I am a Junior Professor in mathematical stochastics and finance at Freiburg University since April 2016.
Previously, I was a PostDoc in Josef Teichmann's working group in financial mathematics at ETH Zürich and in Harvard EdLabs. I did my PhD in mathematics at the University of Vienna in shape analysis and Riemannian geometry on infinitedimensional spaces.
Research interests: stochastic analysis, mathematical finance, stochastic filtering and optimal control, differential geometry in infinite dimensions, shape analysis.
