Claudia Wagner-Riddle

Claudia Wagner-Riddle is a Professor at the University of Guelph, specializing in environmental science with a focus on greenhouse gas emissions and soil health. Her affiliations include NSERC, OMAFRA, and Agriculture and Agri-Food Canada. She holds a B.Sc. in Agronomic Engineering (University of São Paulo, 1982), M.Sc. in Agrometeorology (University of São Paulo, 1986), and a Ph.D. in Atmospheric Sciences (University of Guelph, 1992).

Her research addresses greenhouse gas mitigation in agriculture, soil ecosystem services, and crop rotation impacts on soil health. Notable projects include studying freeze-thaw-induced N2O emissions and the carbon footprint of dairy/beef farming. She leads the Soil Health Interpretive Centre, leveraging lysimeters and micrometeorological techniques for field-scale studies.

• Research Highlights: Freeze-thaw emissions, cover crops, crop rotation diversity, and winter warming effects.
• Awards: 2018 Fellow of the Canadian Society for Agricultural and Forest Meteorology.
• Grants: NSERC Discovery Grants, OMAFRA-University of Guelph agreements, and Grain Farmers of Ontario funding.

Her lab emphasizes graduate student training through structured mentorship and weekly group meetings. Current work explores climate change impacts on agroecosystems and sustainable farming practices.
