My current main interests are: uncertainty quantification for inverse problems from a Bayesian viewpoint, data assimilation, construction of spatial priors using various types of spde, decision and control problems in the presence of uncertainty and the optimisation of expensive functions. At the moment my focus is on the inverse problem for the wave equation and for chaotic dynamical systems such as the Lorenz 96 model, generalised to include unknown and unobserved parameters.
In the recent past I was active in 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.
