I am interested in understanding the physical mechanisms underlying the functioning of biological systems, and especially to all processes involving DNA. The central theme that we develop in the team Multiscale Modeling of living matter (M3V group) is the study of the functional dynamics of the chromatin fiber.

I am particularly interested, in the recent years, in the topology of the chromatin fiber and its role in the interpretation of magnetic tweezers experiments zllowing to manipulte unique chromatin fibers. We hypothesized that a reversal of the nucleosome chirality, induced by the application of a torque, may give rise to a new nucleosome conformation, wound on the right, which we named the reversome.

This work also involved the introduction of new methods for performing simulation, especially developed by Pascal Carrivain during his PhD.

On the other hand, the M3V team has integrated following my arrival, a new line of research, namely the study of the mechanisms of searching for target sequences along the DNA adopted by proteins, and their involvement in the regulation of gene expression. This research line also open the way to the study of important electrostatic effects in chromatin organization.

Our group is also at the origin of the GDR Nuclear Organization and Dynamics (DNA), a CNRS research network including more than 80 French teams working in the broad field of nuclear architecture and functional dynamics of chromosomes.
