How do the chemicals we use impact the world we live in? Prof. Paul Sibley has been investigating this question since joining the University of Guelph in 2000.
An Alumnus of the University of Guelph, Sibley received a M.Sc. in Environmental Biology before moving on to earn his Ph.D. in Biology from the University of Waterloo. Fueled by his passion to understand the risks of chemicals in the environment, Sibley went on to accept a 3-year post-doctoral position at the United States Environmental Protection Agency where he headed a program to develop test methodologies to evaluate risks associated with chemicals in sediments.
Sibley's work aims to help Canadians understand the relative risks associated with everyday chemicals in the environment, with particular interest in developing improved mechanisms to communicate risks to the public, the development of evidence-based policy, and how chemical risks can and should be managed when there are many competing objectives.
To Sibley, understanding the risks associated with chemical use is key to using them responsibly. To-date he has investigated many classes of chemicals, ranging from pesticides to pharmaceuticals and personal care products. He also examines hazardous algal blooms in Lake Erie, the effects of invasive species on forest ecosystems, and the effects of forest management and natural disturbance on aquatic ecosystems and their services.
