I have over 30 years research experience with a track record of highly collaborative, interdisciplinary research in Earth System Science. I was principal developer of the LPJ model, the World’s most highly cited Dynamic Global Vegetation Model, and have published extensively on modelling plant physiology, vegetation dynamics, biogeochemical cycles, and ecosystem-atmosphere interactions. I was theme leader on plant physiology (to 2010) and vegetation dynamics and disturbance (to 2014) and now leader of community experiments of the Joint UK Land Environment Simulator, JULES. I co-lead TRENDY, the international team providing land flux estimates for the Global Carbon Project’s (GCP) annual carbon budget update, and GCP’s regional synthesis chapters, and has been contributing author to IPCC.
