معرفی
Myrna Simpson is a Professor at the University of Toronto Scarborough, affiliated with the Department of Physical & Environmental Sciences. Her research focuses on molecular-level environmental chemistry, particularly soil organic matter dynamics, climate change impacts, and ecotoxicological applications of metabolomics. She leads the Environmental NMR Centre, utilizing advanced techniques like nuclear magnetic resonance (NMR) and mass spectrometry to study soil carbon sequestration, contaminant sorption, and organismal responses to pollutants.
Her work integrates biogeochemistry, analytical chemistry, and environmental science to address global challenges such as Arctic soil thaw, agricultural sustainability, and early warning systems for ecosystem health. Current initiatives include the NSERC-funded Climate-Smart Soils CREATE program, enhancing training in agri-food sector soil science. Simpson collaborates across disciplines, engaging with long-term ecological research sites and international networks.
Research interests span soil organic matter turnover, contaminant bioavailability, and metabolomic tools for ecotoxicology. Her group develops NMR-based methods to assess sub-lethal toxicity in organisms like earthworms and Daphnia, advancing rapid environmental health monitoring. Ongoing projects include studying permafrost thaw transitions, bentonite clay interactions, and industrial effluent analysis using NMR spectroscopy.
Her contributions bridge fundamental science and applied solutions, emphasizing interdisciplinary approaches to environmental challenges. Simpson actively mentors students through graduate programs in Chemistry and Environmental Sciences, as well as undergraduate research opportunities.
