I’m Professor of Earth System Science at the University of Exeter. My work focusses on the transformation of our planet.

Reading Jim Lovelock’s books on Gaia ignited my passion for studying the Earth as a whole system. I study how our remarkable planet came to be the way it is now. I study how humans are transforming the Earth’s system and how we might create a flourishing future within that system.
