Research interests
I am an Associate Professor in Hydrology and UKRI Future Leaders Fellow based in the School of Geographical Sciences. My research focusses on understanding and predicting hydro-climatic extremes (floods and droughts) in changing environments. My expertise centres on building, applying and evaluating hydrological models for the improved simulation of water systems from local to continental scales across large samples of catchments. I built and co-developed the hydrological model DECIPHeR which is now used for hydrological predictions across the UK and led the development of the CAMELS-GB dataset consisting of hydrometeorological timeseries and landscape attributes for 671 catchments across the UK.
I am an elected ordinary committee member for the British Hydrological Society.
My team and I work closely with communities, water companies, and regulatory bodies across the UK, and are currently involved in projects on (1) delivering a £38M large-scale investment in flood and drought research infrastructure in the UK and (2) informing the development of new water infrastructure as part of the Ofwat-funded RAPID programme.
