     Experimental models of hydrodynamics in biological systems

Synchronization of driven oscillators is a key aspect of flow generation in artificial and biological filaments such as cilia.  The difficulty lies in the fact that the dynamics is non-linear, both at the level of each cilium, and in the coupling between them. We have developed different model experiments using systems of colloidal scale particles driven by optical traps. I will review some of these models and technical challenges we had to address.
