Professor Carl Mitchell
Carl Mitchell is a Professor in the Department of Physical and Environmental Sciences at the University of Toronto - Scarborough, with graduate appointments in the Department of Geography, the UTSC Department of Physical and Environmental Sciences, and the School of the Environment at the University of Toronto. Dr. Mitchell completed his PhD in Physical Geography at the University of Toronto in 2007 and undertook a postdoctoral fellowship at the Smithsonian Environmental Research Center until July 2008, when he was hired as an Assistant Professor at UTSC. Dr. Mitchell is currently the Associate Graduate Chair of the Department of Physical and Environmental Sciences. He served within the earth and environmental science community as the President of the Canadian Geophysical Union (2019-21) and is current Past-President. Professor Mitchell is also an Associate Editor at Frontiers in Environmental Science.
Dr. Mitchell usually teaches:
Dr. Haiyong (Planck) Huang, Postdoctoral Fellow
Dr. Huang completed his Ph.D. research in 2024, investigating molecular interactions between dissolved organic matter, sulphur and mercury to better understand when and where mercury becomes more bioavailable to microbes who produce methylmercury. His postdoctoral research is diving more deeply into mercury bioavailability in stream sediment.
Dr. Wai Ying Lam, Postdoctoral Fellow
Dr. Lam completed her PhD in 2024 after studying the hydrology of northwestern Ontario boreal watersheds, how physiography and forest harvesting impact mercury export from these watersheds, and the biogeochemical implications related to beaver activity in disturbed watersheds. Her postdoctoral research is examining the broader geographical robustness of mercury-landscape relationships.
Dr. Katrina MacSween, Postdoctoral Fellow
Dr. MacSween joined the group in June 2024 and is working on mercury cycling processes, especially surface-air exchange processes in Canada's North.
Sayuri Sagisaka Mendez, PhD Candidate
Sayuri began her PhD in September 2020. She is conducting a series of lab-scale experiments to broaden our understanding of how land cover changes and climate change impact mercury cycling processes, especially methylation and demethylation.
Sarah Gigi, MSc Student
Sarah began her MSc in May 2023. She is examining mercury methylation and demethylation processes in High Arctic sea ice.
Erika Bullen, MSc Student
Erika began her MSc in May 2024. She is examining mercury methylation, demethylation and hydrological mobility processes in permafrost soil and sediment.
Sarah McGonigal, MEnvSc Research Student
During summer 2024, Sarah is carrying out experimental work with High Arctic permafrost to examine mercury stocks and potential mobility.
Alexandria White Eby, Environmental Science Undergrad Researcher
Alexandria has been a part of the lab since 2022 in various research support roles. She also completed her undergrad thesis research with the group, looking at sulphur-mercury interactions in soil.
Yijin Zhang, Centre for Global Change Science Intern
Yijin joined the lab in the summer of 2024 to do research on how the production of reactive oxygen species by plants affect soil biogeochemistry.
Oviga Yasokaran, Environmental Science Undergrad Researcher
Oviga joined the lab in the summer of 2024 to work on mercury-sulphide nanoparticle synthesis and characterization.
