Donald Mackay is the founding director of the Canadian Environmental Modelling Centre at Trent University. As one of Canada's leading scientists, he has greatly contributed to the quality and our stewardship of the global environment. Recognized internationally for his models describing the behaviour and effects of oil spills, he later developed an innovative system to predict the fate and effects of chemicals in the environment. The "Mackay models," as they are known, are used as the basis of regulatory and environmental policy decisions around the world. In 2001, he was the first Canadian recipient of the prestigious Honda Prize for his work on eco-technology.
