Tutorial Fellow, Trinity College, Oxford

I am an applied mathematician, using mathematical models to investigate scientific problems. Much of my research relates to problems in the geosciences - a particular focus currently is on glaciers and ice sheets.

A list of publications is here.

Please get in touch if you'd like to know more, especially if you're a student interested in research.


Slides from lectures at Karthaus 2017 are here (continuum mechanics), here (sliding), here (hydrology) and here (geomorphology). Exercises are here and solutions are here. Older slides are here (rheology) and here (thermodynamics).

Slides from lectures in Iceland 2013 are here.
