About me

Applied Mathematics
Mathematical Biology
Biofilms
Cell Biophysics
Partial Differential Equation Models

I am an applied mathematician interested in biological and fluid mechanics problems, especially those involving partial differential equations. Much of my research involves understanding the mechanics of biological cells. This ranges from modelling how protein networks in individual cells generate the forces required for movement and division, to macroscopic modelling of complex colonies.
