Born: 1975

Interests: Complex Fluids, Non Linear Hydrodynamics

I focus on several issues related to the hydrodynamics of complex fluids, chaotic fluid motion:
- elastic turbulence of dilute solutions of linear polymers
- the solid-fluid transition in yield stress fluids
- the transition to turbulence of a yield stress shear thinning fluid
-drag reduction in plastic fluids
- develop "smart fluids" that adapt their local rheology to the flow environment
