About Me

EPSRC funded Mathematical Biology PhD student, part of the Applied and Computational Mathematics (ACM) Research Group at Cardiff University, supervised by Dr Thomas Woolley.

I am treasurer and webmaster of the Cardiff SIAM-IMA Student Chapter, and a member of the Society for Mathematical Biology.

Research

My research focuses on the mathematical modelling and simulation of cell motion caused by pressure-driven membrane protrusions known as blebs. In particular, I am interested in how a cell’s migration characteristics relate to both the distribution of bleb nucleation sites over the cell surface and the local geometry of the substrate on which the cell resides.

In collaboration with researchers at the University of Reading, I am developing a cell tracking pipeline for extracting motion characteristics from microscopy video data. This collaboration originated from participating in the Medical Imaging Hackathon in 2025, which I am helping to organise for 2026.

I have also developed an open-source software package for the semi-automated detection, measurement, and counting of linear features in biological images using wavelet and Fourier transform methods, with applications ranging from growth-ring analysis in bivalve shells to any domain requiring approximately linear feature extraction.
