I am interested in using analytical and numerical techniques to understand complex interface phenomena and have particular expertise in asymptotic analysis, applied bifurcation theory and the finite element method.
I am a postdoctoral research associate working with James Sprittles and Duncan Lockerby on their grant “Dynamic Wetting & Interfacial Transitions in Three Dimensions: Theory vs Experiment”. I completed my BSc in Mathematics in 2005 at the University of Nottingham before spending a number of years teaching in the UK school system and abroad. In 2014 I started a PhD in Applied Mathematics on a co-tutelle between the University of East Anglia, UK and the University of Adelaide, Australia working on the asymptotic analysis of the equations governing water waves over a topographic forcing and with pressure distributions on the surface. I completed this in 2018 and afterwards worked for two years in the University of Manchester developing numerical and analytic techniques describing the motion of an air bubble in a Hele-Shaw channel using ideas from dynamical systems theory.
