I work mainly on assessing human and climatic impacts on some of the world’s most important freshwater ecosystems, including Lake Baikal and the Aral Sea in central Asia, and the Okavango Delta in southern Africa. Key to much of this work is the use biological organisms and stable isotopes to reconstruct past environments.

My research activity concentrates on understanding the key biological processes that maintain biodiversity. In other words, what acts as the glue to hold ecosystems together? I am particularly interested in the factors that determine species abundance in space and time. There is a particular emphasis on diverse plant communities such as tropical forests, but group member have also studied bacteria, protist and vertebrate communities.

My research focuses on the investigation time-scales of magmatic processes and pre-eruptive magma degassing conditions at active volcanoes, magmatic processes at subduction zones, lithosphere evolution and relationships between magmatism and tectonics. I approach these problems using geochemical analysis and micro-analytical techniques.
