Note: This webpage will no longer be maintained, as I finished my PhD in June 2017 and moved on to a new research position.
I am a PhD student at the Centre for Complexity Science and the Department of Physics, working with Dr. Gareth P. Alexander. My research interests focus around the development of physical models to understand non-equilibrium properties of living systems. With the development of the field of active matter, it has proven insightful to describe suspensions of motile entities, such as bacteria suspensions or cytoskeletal filaments together with their molecular motors, as complex fluids with additional active stresses and liquid-crystalline alignment.
In my PhD I am developing mathematical models to understand the behaviour of such active fluids under geometrical confinement, e.g. when an active fluid forms a droplet on a substrate or coats a spherical vesicle membrane in a thin layer. In particular, I am interested in the effect of topological defects in the alignment on the large-scale flows in such geometries. For instance, defects are found to drive macroscopic motility through the flows they create. Studying simple models analytically and in simulations helps to develop a basic understanding of how curvature and topological constraints influence the dynamics of active fluids and provides a first step towards design and control of biomimetic materials in the future.
