Prof. Dr. Peter K. Friz

Welcome! I am Professor in Mathematics at TU-Berlin, part of the Research Group: Probability Theory and Mathematical Finance.

I am also affiliated to the Weierstrass Institute for Applied Analysis and Stochastics; here is a Brief CV with research interests.

Most recent papers are on the arXiv; you can also have a look at MathScinet (subscribers only ...) or try Google Scholar.

Here is a list of former PhD students, a list of present PhDs & Postdocs and a recent photograph, courtesy of MFO.

Stochastic analysis and rough path theory:

Rough path analysis allows for a fresh, if not revolutionary, view on Ito's important theory of stochastic differential equations. I taught rough path theory in

Cambridge, Columbia and TU-Wien (click here for a set of notes). I have also been acting as organizer for rough path meetings, e.g. as part of 5ECM or SPA09

or most recently SPDE10 at the Newton Institute.

My present research in this area is supported by an ERC Starting Grant (some info); past supporters include the Leverhulme Trust and EPSRC.

Quantitative finance:

The world of finance has become a major consumer of mathematics. In turn, it continues to provide us with good problems. Having spent more than a year on

Wall Street, I prefer financial mathematics with direct industry relevance. For instance, there is an ever-growing need for closed form approximate solutions

derived from various parts of asymptotic analysis. In recent work, we have used large deviations and Tauberian techniques to derive such formulae. I was invited

speaker at meetings such as the Quant Congress Europe or the Bachelier conference.

My present research in this area is supported by and MATHEON; past supporters include the Cambridge Endowment of Research in Finance.
