Biography

Steven Siciliano is a Professor at the College of Agriculture and Bioresources at the University of Saskatchewan, currently on sabbatical leave until June 30, 2026. He holds the NSERC/FCL Industrial Research Chair in Situ Remediation Risk Assessment and is the Director of the CREATE Human Ecological Risk Assessment Program. His research focuses on soil toxicology, specifically the interaction between human actions and soil health. Siciliano explores how pollutants, such as polycyclic aromatic hydrocarbons (PAH) and total petroleum hydrocarbons (TPH), affect soil and human health, emphasizing the importance of site-specific cleanliness for protective guidelines. His lab investigates the biogeochemical cycles, particularly the nitrogen cycle, and their sensitivity to pollutants. He also addresses the ecological and toxicological stressors impacting nitrogen cycle dynamics in Canada’s industrial barrens. In addition to his investigative work on soil health, he examines greenhouse gas production in Arctic and Antarctic ecosystems and explores the effects of environmental factors on microbial composition.
