Our activity consists in a mainly experimental approach of the physics of soft condensed matter and of biological systems.

On the one hand, we study situations in which the non-linearities in the rheological response of complex fluids are at stake and evaluate the pertinency of our findings for explaining some geophysical phenomena. Complex fluids in consideration are, for instance, granular matter, foams and gels.

On the other hand, we study the dynamics of the adhesion to a substrate, a biophysical process which is fundamental to the biological activity of some cells. At the molecular scale, we characterize and model the actin turnover inside the cell, which reminds us crystal-growth phenomena. At the cellular scale, we analyze the behaviour of the cells on various surfaces, which requires the development of new experimental techniques dedicated at the design and characterization of the substrates. 

Finally, let mention some other research activities developped aside of the main research field.
