Research interests
Professor Laurion is particularly interested in the effects of climate change on mixing dynamics and water transparency in lakes and in their interaction with the microbial food chain. Dissolved organic matter (DOM) has a strong effect on water transparency and also influences mixing dynamics in lakes. Professor Laurion studies DOM bio- and photodegradation processes and how these processes affect greenhouse gas production and the carbon cycle.
Her current work focuses on the impact of permafrost thawing on the carbon cycle in northern environments. Permafrost thawing creates ponds where biological activity and solar radiation can cause the carbon stored for millennia in the tundra to be released into the atmosphere in the form of CO2 and CH4. This transfer could represent a positive climate feedback mechanism, as these systems are natural carbon reactors. Professor Laurion also studies the greenhouse gas emissions from small eutrophying lakes and sewage treatment ponds.
She is also interested in the development of optical tools for the detection of algal and cyanobacterial blooms in lakes in Quebec, including hyperspectral detection (visible and near IR), which can be applied to remote sensing with satellites and drones. This work is done in close collaboration with Professor Karem Chokmani’s team.
