This year marks Spencer’s 40th year at the University of Toronto, where he has taught tens of thousands of undergraduates about the importance of ecology and evolutionary biology, how the natural world shapes their lives, and how their activities and choices impact life around them. Although Spencer will formally retire in July 2018, he will maintain his very active research program at the university.
