Introduction

Figure 4

We are interested in developing hydrodynamic theories of active matter. We are working on the mechanics of active surfaces, which are subjected to internal forces and torques.

Active tensions tend to contract the surface area of the manifold, while active moments tend to locally bend the surface. We are interested in the surface shape changes and internal flows, which result from these active forces. We are also interested in nematic active fluids, and the chaotic patterns that emerge in these systems.
