Research interests

My current main research interests are wave propagation in heterogeneous media and kinetic models for fluid mechanics.

Previous interests included: inverse problems, the adaptive management of natural resources, flow through porous media, grid generation and numerical simulation of elliptic pde with tensor coefficients. Until March 2016 I was funded by the Oxford Martin School as co-director of the programme on Modelling and Predicting Climate and as a PI on the Oxford Martin Programme on Resource Stewardship.
