Research Interests

My research focus lies on stochastic processes and dependence concepts in extreme value theory, a branch of probability and statistics that provides theoretically sound procedures for extrapolation beyond the range of data (as good as possible, knowing the limits is also an important issue). Its methods are usually relevant for institutions that are exposed to high risks, for instance, financial services and insurance companies or environmental engineering institutions.

So far, I have been involved in projects concerning the following topics:

Extreme value theory (correlation functions and dependence concepts for extreme values, connections to stochastic geometry and risk measures, conditional independence)
Realisability problems (that deal with the existence of stochastic models with some prescribed distributional properties, connections to convex geometry)
Stochastic processes (in particular Gaussian and max-stable processes, construction principles, simulation, R software RandomFields)
Markov chains (modelling the evolution of the chain after an extreme event)

With my research I would like to contribute to the development of improved tools for the analysis and prediction of rare events, in particular their temporal and spatial extent, and the rigorous verification that these tools are suitable in very general situations.
