Research Interests

I lead the Hydrological Processes and Extremes (HPE) Group at the UK Centre for Ecology & Hydrology in Wallingford. The HPE Group encompasses hydrologists and modellers who research how hydrological extremes (e.g. floods and droughts) might change in the future.

Significant developments include the Grid-to-Grid (G2G) hydrological model and its application across the UK at a 1km resolution to investigate the effect of climate change on river flows. Recent research includes the development of a grid-based, integrated model to estimate pools and fluxes of nutrients across the UK as part of the NERC Macronutrient Cycles programme, the NERC-funded MaRIUS project improving the understanding of droughts across the UK, and a UK-wide seasonal hydrological forecast system (Hydrological Outlooks) delivered through the Environmental Science to Services (ESSP) collaboration with the Met Office, the Environment Agency and BGS.
