Professor Jon Lloyd is a plant ecophysiologist by training, but has devoted much of his recent research to understanding underlying controls on ecosystem carbon fluxes. He has extensive experience in the modelling and measurement of terrestrial carbon and water vapour fluxes at the leaf, canopy and global level. Prior to accepting the Chair of Global Ecosystem Function at Imperial College, Jon held the Centenary Chair in Earth System Science in the School of Geography at the University of Leeds from 2004-2013. From October 2009 to July 2013 he was on leave of absence from his UK commitments, holding Visiting Professorships at the University of Queensland and James Cook University. During this time, for a brief period he was also the Director of the Australian Terrestrial Ecosystems Research Network. From 1997-2004 he was head of the Biosphere-Atmosphere Interactions Group at the Max Planck Institute for Biogeochemistry in Jena, Germany, and before that a Fellow in the Environmental Biology Group at the Australian National University, Canberra.

Research interests

A plant physiologist by training, Jon has long been interested in exchanges of CO2, water vapour and energy between natural ecosystems and the environment especially in terms of the underlying physiological mechanisms and ecological implications. More recently, his work has also moved below-ground with a developing interest in the relationship between soil conditions and ecosystem structure, dynamics and productivity. He is also interested in working on the improvement of climate change predictions through the integration of physiology into models of mass and energy transfer between the atmosphere and the biosphere and  maintains an active interest in isotopic fractionations during photosynthesis and respiration (at plant, ecosystem and global scales) and in the past has also published extensively on atmospheric trace gas composition and change in relation to climate.
