I’m interested in quantifying and understanding the carbon cycle of wetlands, with a particular focus on tropical peatlands. Tropical peatlands, the most carbon dense terrestrial ecosystems in the world, are a substantial but highly uncertain component of the global carbon cycle with wide-ranging estimates of their total area (441,025 -1,700,000 km²), and total below-ground carbon (105-215 Pg C). Protecting and restoring tropical peatlands can make a significant contribution to limiting CO₂ emissions and global warming, but policy instruments such as REDD+ and Nationally Determined Contributions to the Paris Agreement must be informed by high resolution maps of peatland distribution and an understanding of how carbon stocks and fluxes will respond to climate and land-use change. Our group uses fieldwork, remote sensing, modelling and paleoecology to address these uncertainties.
