Dr Chris Doughty
Position:Lecturer in Ecosystem Ecology
Member:ECI Ecosystems Research Theme
I am a lecturer in Ecosystem Ecology within the Environmental Change Institute (ECI) at the University of Oxford. My main interest is in understanding tropical forest carbon fluxes, through remote sensing, eddy covariance, leaf gas exchange and intensive carbon cycle plots. My secondary interest is in understanding how the Pleistocene Megafauna extinctions impacted global biogeochemical cycles, climate and global tree diversity.
I majored in Environmental Science at the University of California, Berkeley and subsequently completed a PhD in Earth System Science at the University of California, Irvine. I spent two years as a postdoctoral fellow in the Department of Global Ecology at the Carnegie Institution, Stanford. I then accepted a junior research fellowship in tropical forest ecology in the Ecosystem Dynamics group at ECI. In April 2013 I began a lectureship in the same department.
I am coordinating research at 17 rainforest plots in 6 sites across the Amazon basin. At these plots, intensive monitoring of forest carbon cycling and allocation will: 1) provide baseline estimates of current forest carbon storage, and 2) track ongoing changes in forest carbon cycling. These results will help develop the next generation of coupled atmosphere-biosphere models and guide international climate policy.
I also have projects to understand the role that large animals play in biogeochemical cycling over continental regions and long periods of time; to understand how montane ecosystems contribute to global weathering and control long-term global climate; and to understand how tropical forest leaf traits (i.e. photosynthesis) can be predicted by leaf spectroscopy.
