I am particularly interested in ice-sheets and glaciers, and use mathematical models to understand how these vast bodies of ice behave, especially in response to past and future climate changes.
I am an applied mathematician, currently specializing in applications of mathematics to Earth Science. I was a student at Trinity, where I studied for an undergraduate Masters and then a DPhil in Mathematics. Following an appointment as a Postdoctoral Research Fellow at the University of British Columbia, I returned to Oxford in 2013, as a University Lecturer in the Mathematical Institute and a Tutorial Fellow at Trinity.
I cover tutorials for most of the applied components of the maths courses in the first and second years. This includes elementary calculus, differential equations, geometry, dynamics, probability, statistics, fluid dynamics, and quantum mechanics. I am also responsible for organizing college tutorials, and advising undergraduate and graduate students in maths and related subjects.
In the Mathematical Institute, I give university lecture courses in mathematical modelling and fluid dynamics.
My research interests are in physical applied maths, and are currently focussed on the Earth Sciences. Other research projects also relate to the mechanics of the Earth, including aspects of volcanology, soil mechanics, and erosion, and I am also involved in a number of industrially focussed mathematical modelling projects.
