Research interests

I am a CEH Fellow and a Lecturer in Physical Geography at Oxford University.

I previously worked as a Senior Environmental Modeller at at CEH.

My research interests lie in exploring the links between land-surface 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. In my role as an Environmental Modeller at CEH at Wallingford, I am responsible for developing hydrological models for use in climate change applications.

Before joining CEH, I completed a PhD in the Department of Earth Sciences in Cambridge on the erosion of tectonically-active mountain belts. This work involved estimating erosion rates in Taiwan using modern river sediment loads, Holocene river incision and thermochronometry on million-year time-scales.
