I studied theoretical physics at the University of Lausanne where I did my Ms dissertation «On Supersymmetric Extensions of Poincaré Lie Superalgebra» with Jean-Jacques Loeffel and my PhD dissertation on «Physical and statistical properties of random knots» with Jacques Dubochet and Andrzej Stasiak. Together with Nicolas Monod, I also founded a book series, Arkhaï, during my studies.
My current duties include research in forensic molecular genetics, supervision of master students, big data management and high-performance computing.
For students, I give a lecture series entitled Interdisciplinary Research Methods in Computational Biology.

Tobias explores the intricate dynamics of bacteria engaged in cooperative behavior in silico. This work is done together with the group of Rolf Kümmerli. For additional details on this project, please also visit his page.
Microbes share secreted beneficial metabolites (i.e. public goods) among community members. This type of cooperative behavior can be weakened by cheater microbes that do not invest in public goods production, but take advantage of them nevertheless. From an evolutionary perspective, it is puzzling to understand why cooperation can be observed nowadays even if it is not favored by natural selection.
It turns out that there are many loopholes in such a simplistic reasoning. Our in silico experiments, based on a custom-made simulation environment that can run on large clusters (see the article in the Scientific Computing World), show that cooperation can nicely flourish in the presence of cheaters under the right environmental conditions.
Furthermore, bacteria are able to evolve what we would qualify as policy mechanims that prevent the emergence of cheaters in the community. We are currently exploring this phenomenon.
