Steven D Siciliano is a NSERC/COOP Industrial Research Chair in the Department of Soil Science and a member of the Toxicology Group. He investigates how humans alter soil microbial ecosystems, how we can use these same microbial ecosystems to mitigate adverse effects, and how these soils pose a risk to humans, plants and invertebrates. Working closely with the Federated Cooperatives Limited (FCL) research team, Steven is investigating how we can leverage existing soil microorganisms to sustainably mitigate inadvertent releases from the distribution and retailing of fuel and agrochemicals. He also collaborates with Professor Eric Lamb investigating plant and microbial interactions in the northern Prairies and High Arctic. Steven also works with Professor Derek Peak exploring mineral and microbial interactions during hydrocarbon and metal remediation. To assess the risk to humans from polluted soil, Steven collaborates with Professor’s Wickstrom and Weber to explore how to estimate human exposure to soil pollutants. Steven’s applied research has helped FCL reduce its site clean up cost by over 20%. Academically, Steven’s research has been well received with his 150 contributions being cited over 5000 times and he serves on numerous grant review panels.
