Currently I am Lecturer at King's College London in the Financial Mathematics group of the Department of Mathematics (Web page at King's College), a Visiting Researcher at the Alan Turing Institute (Web page at the Turing Institute) and Honorary Lecturer in the Department of Mathematics at Imperial College London (Web page at Imperial College). My research interests are in the area of Stochastic Analysis and Mathematical Finance. They include

  • Numerical methods as well as machine learning techniques for option pricing, forcasting and simulation.

  • Smile asymptotics for local- and stochastic volatility models (rough volatility models and SABR-type models in particular).

  • Laplace methods on Wiener space and heat kernel expansions.

Short CV:

Between 03/2016 and 09/2017 I was PI of the research project SNSF project 165248. The research focussed on model risk and implied volatility surface dynamics with a particular emphasis on `Rough Volatility Models'. The research was funded by the Swiss National Science Foundation and was carried out at Imperial College London in collaboration with TU Berlin, and the Weierstrass Institute for Applied Analysis and Stochastics.
