I hold the position of Chair in Wetland Science in the School of Geography at the University of Leeds. My research looks to understand ecosystem dynamics in wetlands, particularly peatlands, with a focus on the water and carbon cycles and on the use of numerical models to simulate these cycles.

Peatlands are globally-important carbon stores (they contain at least a third of the global soil carbon store) and are both sinks and sources of atmospheric carbon dioxide and sources of atmospheric methane. Because of this, they are thought to exert an important control on global climate.
