Mathematical Modeling of Microbiomes

Research group in Marseille

Welcome!

We are a research group based in Marseille, France, close to the sea and its beautiful Calanques. Our group is based at the Laboratoire de Chimie Bactérienne, a joint research unit supported both by CNRS and Aix-Marseille Université. We are also a part of and funded by the Turing Center for Living Systems.

We are a group of theoretical biologists with various backgrounds, ranging from biochemistry to applied mathematics. Our main activity is the mathematical modeling of microbial dynamics, especially when microbes form interacting communities called microbiomes. We have projects that progress in close association with data collection, through experimental collaborations, and others, more conceptual, that explore the fundamental assumptions of evolution in constrained fitness landscapes. Our common languages are those of theoretical ecology and evolution, as well as dynamical systems. Feel free to explore this website to learn more about us!
