Research

I am a theoretical probabilist by training (and by heart) but through my collaboration with Adrián González Casanova, Noemi Kurt and Jochen Blath I was introduced into the world of probabilistic population genetics that has since moved into the center of my research.

It is an area where math is inspired and motivated by biological phenomena. This can on one hand lead to exciting theoretical mathematical observations and objects (that no biologist will care much about, but that are fascinating to us mathematicians) and on the other hand to „applied“ results that can help shed some light on questions in theoretical biology.

Currently my main two aspects I am studying are dormancy and coordination. Dormancy refers to the capacity of individuals in a population to enter (and exit) a „protected“ state during wich reproduction is halted – think of seeds for plants or rather cysts for some amoeba. By coordination we very generally refer to the effect of evolutionary events being driven by a random environment rather than independently – an example of this is rare selection (as opposed to the classical weak selection) when selection events occur rarely, but then are of the order of magnitude of the population size. Like what might have happened to these lizards.

As part of my PhD I also had the privilege of working on percolation and random dynamical systems under the supervision of Michael Scheutzow.

Collaborative Research projects

I am a PI in the IRTG2544 Berlin-Oxford “Stochastic Analysis in Interaction” where I have the pleasure of supervising a PhD Student – Marta dai Pra – jointly with Alison Etheridge from the University of Oxford.

I have a project within the Berlin Mathematics Research Center MATH+ titled EF 4-7 „The impact of dormancy on the evolutionary, ecological and pathogenic properties of microbial populations“. This is jointly with Jochen Blath from Goethe- University Frankfurt (formerly TU Berlin) for the position of our PhD student Tobias Paul.

I was a PI in the RTG 2131 „High dimensional phenomena in probability – fluctuations and discontinuity“ when I was at the Ruhr-university Bochum (joint RTG with University Duisburg-Essen and TU Dortmund) where I supervised my PhD student Nils Hansen.
