In 2017 I joined Cardiff University as a lecturer teaching on the new Financial Mathematics degree scheme.

My research focus lies on multivariate, spatial and temporal dependence phenomena in extreme value theory. The latter is a branch of probability and statistics that provides theoretically sound procedures for the quantitative assessment or rare and typically hazardous events (as good as possible, knowing the limits is also an important issue). Its methods are genuinely relevant for institutions that are exposed to high risks, for instance, financial services and insurance companies or environmental engineering institutions.

Since 2017 I am a member of the editorial board of the journal Extremes.

**Recent activities**

In February 2018 I organised a Mini-Workshop on Extreme Value Theory at Cardiff University's School of Mathematics (with a focus on recent challenges and spatial applications). Many thanks for everyone's contributions!

In 2019 and 2020 Marie Ekström, Owen Jones and I are organising two Workshops on Extremal Trends in Weather (WET Weather) under the umbrella :-) of Cardiff's Water Research Institute.

Currently I work on https://arxiv.org/abs/1809.09042 with Marco Oesting.

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.
