Professor Peter Lafleur
B.Sc., Brandon University
M.Sc., Trent University
Ph.D., McMaster University
Research and Teaching Interests:
Peter Lafleur’s research is located in the fields of climatology and hydrometeorology. His specific research interest is the atmosphere-ecosystem exchange of carbon dioxide and water in peatland and tundra environments. Current projects include ecosystem carbon measurement and modeling at the eastern peatland station of the Fluxnet Canada Research Network and investigation of carbon exchange variation between tundra types in the central North West Territories. Prof. Lafleur currently teaches courses in microclimatology, global climate systems, hydrometeorology, and field based research.
