Elyn Humphreys studies the exchange of carbon dioxide, water vapour, and energy between ecosystems and the atmosphere and the effects of natural and human-induced disturbances on this type of ecosystem function. Her research is currently focused on interactions between climate change and peatland ecosystems in temperate and arctic regions. These ecosystems have vast stores of soil carbon but small changes in climate have the potential to alter the subtle balance between carbon uptake through photosynthesis and loss through respiration.

Elyn received her B.Sc. at the University of Guelph in Plant Biology and then went to the University of British Columbia where she completed her M.Sc. and Ph.D with the biometeorology research group in the Faculty of Land and Food Science. Before arriving at Carleton in 2005, she held an NSERC Postdoctoral Fellowship the Dept. of Geography at Trent University.
