Research

I belong to the Earth Systems Science Research Group at the University of Reading. My main research interest is in the use of optical and radar remote sensing for dryland geomorphology and palaeoenvironmental reconstruction, with a special focus on aeolian and fluvial processes, weathering, soils and geochemistry.

The following links provide access to brief, illustrated summaries of current research projects. Please contact me if you would like to know more.
