I am an Associate Professorship in Physical Climate and the David Richards Tutorial Fellow at Wadham College. I also hold a Leverhulme Trust Research Leadership Award. You can find a short version of my CV here.

I lead the Atmospheric Processes group. For more details about our research, please see the group pages. But, in summary ....

We work to understand the role of uncertain small-scale processes on weather, seasonal and climate timescales. We combine this understanding with expertise in numerical modelling to improve weather and climate models – our code can be found in various weather forecasting models around the world. We approach research problems by combining theoretical ideas with observational analysis and a hierarchy of models, ranging from simple dynamical systems to complex global circulation models. A key theme running throughout is uncertainty quantification in the context of modelling and prediction.

A growing area in our group is the application of sophisticated Machine Learning tools to problems in this area. I co-lead the University of Oxford Intelligent Earth Centre for Doctoral Training which will train a new generation of DPhil (PhD) students to tackle some of the most pressing environmental issues using Artificial Intelligence and Machine Learning.

Internationally, I am leading the international Model Uncertainty-Model Intercomparison Project (MUMIP), a joint venture of the World Weather and World Climate Research Programmes, with contributors from modelling centres worldwide. I was awarded the American Meteorological Society Clarence Leroy Meisinger Award and the International Association of Meteorology and Atmospheric Sciences Early Career Scientist Medal in recognition of leadership in this area. I contributed to Chapter 4 of the IPCC AR6 on ‘Future global climate: scenario-based projections and near-term information’, and am a member of the International Commission on Dynamical Meteorology (ICDM), part of the International Union of Geodesy and Geophysics (IUGG). I am also an associate editor at JAMES (Journal of Advances in Modeling Earth Systems).
