Research Overview

My research investigates how ecosystems respond to change. I’m happiest when working in forests but I also make the occasional foray into grasslands. My main research focus lies in determining how interactions between above- and belowground processes affect ecosystem function. I work in the UK, Panama and Borneo using a wide range of tools borrowed from biogeochemistry, plant-, soil, and microbial ecology. I’m also passionate about science communication and public engagement with science. More details can be found on my project website http://www.forestprime.com and at http://www.besfest.org
