Nigel Roulet

Nigel Roulet is a Distinguished James McGill Professor of Biogeosciences at McGill University's Department of Geography. He also holds a Trottier Institute for Science and Public Policy (TISPP) Fellowship. His research focuses on ecohydrology, biogeochemistry, and the carbon dynamics of peatland ecosystems. He explores how climatic and hydrological changes impact peatland function, particularly in boreal, subarctic, and arctic regions. His work integrates observational, experimental, and modeling approaches.

Roulet's education includes a Ph.D. from McMaster University and B.Sc./M.Sc. degrees from Trent University. He teaches courses in environmental systems, hydrology, and biogeochemical cycles. His research group investigates peatland responses to land-use changes (e.g., peat extraction) and climate shifts, emphasizing carbon, energy, and water balances.

Key research themes include peatland restoration's climate impact, methane production dynamics, and the role of microbial communities. His work has been recognized with awards like the Royal Society of Canada Fellowship and contributions to the IPCC's 2007 climate report. He actively supervises graduate students and postdoctoral fellows, offering opportunities in biogeochemistry, hydrology, and climate science.

Roulet collaborates internationally, with fieldwork in North America and Europe. His lab employs advanced modeling (e.g., McGill Wetland Model) and remote sensing to assess peatland resilience and carbon sequestration potential. Recent studies highlight peatland vulnerability to permafrost thaw and the importance of restoration for mitigating climate impacts.
