Dr. Kevin McCann

After completing a degree in mathematics at Dartmouth College, I returned to school to pursue an interest in applying math to ecology. I was trained by Dr. Peter Yodzis and Don DeAngelis as a graduate student before going to University of California to work as a post-doctoral researcher with Dr. Alan Hastings. From there I took a faculty position at McGill University where I worked closely with ecosystem ecologist Dr. Joe Rasmussen.
In 2003, I returned to Guelph where my lab studies the structure and function of food webs. We employ a range of approaches (theory, lab and field) and although we focus on aquatic systems (currently lakes and seagrass food webs), our approach is quite broad and includes collaborative work with soil, forest and grassland ecologists.
