I study biology through mathematical models. My main focus is on investigating stochastically induced phenomena as extinction or invasion of genetic traits or species. To put it (even) more broadly: I am interested in noise in populations and cells.

My fields of application can be split into Biochemical Systems and Evolution & Ecology. Most of my models are built on individual based dynamics and their large population approximations.

Biochemical Systems
The explicit quantification of noise (variance) in gene regulatory systems is accessible through quite recent developments of probabilistic techniques. Applying these to shed more light on gene regulation is what I am currently interested in.

Evolution and Ecology
One of the most interesting current concepts (in my opinion) is the connection of ecological processes and evolutionary dynamics. Studying fixation probabilities of traits in these scenarios poses a great challenge due to the increased complexity as opposed to usual evolutionary models. More precisely I try to answer the following question: how does demographic or environmental stochasticity affect evolutionary dynamics?
