Qualifications
MA; MSc; DPhil (Oxford)
Academic background
I was a mathematics undergraduate and graduate student at St Anne’s College (Oxford) in the 1990s. My DPhil thesis was about 'The mathematics of foam'. I spent two years at Sheffield University working in the Department of Pathology, where I constructed some of the first mathematical models for vascular tumour growth. I returned to Oxford in 2001 to a position at the Mathematical Institute as a Research Facilitator (the first of its kind) which combined research with getting grants. This was a very successful role and in 2008 we won a $25M grant from KAUST in Saudi Arabia to set up the Oxford Centre for Collaborative Applied Mathematics (OCCAM). I was appointed to a faculty position in 2008 and was OCCAM’s Associate Director from 2008-2014 (when the money ran out). I then spent 10 years as co-Director of the EPSRC Centre for Doctoral Training in Industrially Focused Mathematical Modelling (InFoMM), through which Oxford trained 68 applied maths DPhil students in the skills needed to tackle 21st century industrial problems using cutting-edge mathematical techniques. At its peak, InFoMM had over 80 company partners.
In 2023 I was appointed as the inaugural Scientific Director of the UK Knowledge Exchange Hub for Mathematical Sciences (KE Hub). The KE Hub aims to bring business, industry and government to the front door of academic mathematical sciences and vice versa. There are currently 63 departments across the UK involved.
I joined Christ Church’s teaching team in October 2004.
Undergraduate teaching
I teach first and second year applied mathematics – calculus, dynamics, ODEs/PDEs, calculus of variations, and fluid mechanics. I regularly teach intercollegiate classes in fluid mechanics or applied partial differential equations for third years, as well as lecturing (e.g. viscous flow, a third-year course).
Research interests
My research career has been centred around explaining phenomena arising in applied science, industry and medicine. Often these involve fluid mechanics or heat and mass transfer. One key area of my work has been the study of surface-active agents, such as washing up liquid, which modify the surface tension of air-liquid interfaces and can fundamentally change fluid flows. My recent work has focused on models for filters, cleaning and decontamination, flows of glass, operation of piezoelectric composite devices, silicon and aluminium production, surfactant systems out of thermodynamic equilibrium, and a few disconnected industrial processes.
