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.
