Research interests:

I study the effect mechanical interactions on the growth of cellular
assemblies using computational techniques. Cellular assemblies are an
example of ‘active matter’, non-equilibrium systems that consume
energy to perform work through processes such as growth and division.
I am interested in the dynamics of cellular assemblies both in
confinement. When confined, cellular assemblies jam at a high
densities, causing the internal pressure to increase dramatically and
growth to occur slowly and intermittently. Working alongside with
experimentalist Morgan Delarue, Pawel Gniewek and I are developing a
computational framework to study confined cellular assemblies.
