I use mathematical modelling to support research in the biological and physical sciences. Much of my work involves understanding the mechanics of biological cells, including elucidating how protein networks enable cell movement and division, modelling wound healing, and understanding how yeast and bacterial colonies grow.
I enjoy teaching students of all levels and backgrounds, and am an active member of the Industrial and Applied Mathematics (ANZIAM) division of the Australian Mathematical Society.
