Profile
Expertise

As a biogeochemist and applied ecologist, my main research interests comprise the cycling of nutrients through aquatic ecosystems, the interaction between plants and their abiotic environment and the factors controlling emission or storage of greenhouse gasses. Furthermore, I am interested in the application of ecology to the management and restoration of aquatic systems. In my work, I use a combination of field measurements and more controlled experimental approaches to study biogeochemical processes across different levels of organisation. I am also involved in multiple outreach programmes to engage the public with ecology and climate change science.
