Academic Profile

Simon Dadson is a University Lecturer in Physical Geography and a Fellow of Christ Church. Simon's research focuses on the processes that link climate, hydrology, and geomorphology. These links range from the potential impacts of future climate change on river flows, to the study of how continental-scale weather patterns have influenced the development of mountain topography over the past few million years. Prior to arriving at the School of Geography and Environment, Simon was a Senior Environmental Modeller at the Centre for Ecology and Hydrology in Wallingford where he remains a CEH Fellow.
