Key Facts:

Hannah Cloke is a hydrologist and physical geographer specializing in land surface modelling, flood forecasting and catchment hydrology. She works closely with the Environment Agency, the Met Office, the Flood Forecasting Centre and the European Centre for Medium-Range Weather Forecasts as well as a wide range of other national and international partners. She recently advised government on the Jan/Feb 2014 floods crisis and provided substantial expert commentary in the media. 

Hannah obtained a BSc (1999) and PhD (2003) in Geography from the University of Bristol. She then worked as a Research Associate at the European Commission Joint Research Centre in Ispra, Italy, working on the European Flood Alert System and then from 2004 lectured at in the Department of Geography at King’s College London. In 2012 she was appointed Associate Professor of Hydrology at the University of Reading; a joint post between the Department of Geography and Environmental Science and the Department of Meteorology.

Hannah is currently a member of the of the Environment Agency-DEFRA R&D flood science programme advisory group. She is a member of the NERC Peer Review Panel C, Floods theme coordinator for the International Hydrological Programme (IHP): FRIEND network, and a committee member of the EGU Hydrology section: Catchment hydrology. She is on the editorial board of the journals Meteorological Applications, Hydrology and Earth System Science and Hydrology Research, and is guest editor for Hydrological Processes.

Hannah is an active member of the HEPEX project and recently served on the British Hydrological Society committee.
