Me in Greenland, August 2008I am a research fellow in the Department of Geography, UCL, working within the Environmental Change Research Centre (ECRC) and with the ECRC's consultancy arm Ensis.

I am interested in environmental change and human impacts upon aquatic environments. In particular, I am interested in understanding how lakes in remote regions have changed in the past and how human impacts like acidification, eutrophication, and climate change have affected the ecology and biogeochemical cycles of lakes in the past and how they will be affected in the future.

Find out more about my research interests.

I convene the ECRC's short course in Numerical Analysis of Biological and Environmental Data and contribute to teaching on the undergraduate course Ecological Patterns and Processes.
