Sasa Stefanovic is a Professor in the Department of Ecology and Evolutionary Biology at the University of Toronto. He holds an MSc from the University of Paris VI and a PhD from the University of Washington, Seattle. His research focuses on plant systematics, employing both molecular and traditional tools to address questions at both higher and lower taxonomic levels. His research is particularly concentrated on the family Convolvulaceae, specifically the parasitic genus Cuscuta. He utilizes a comparative approach and broad taxon sampling in conjunction with robust phylogenetic frameworks to explore patterns and processes of plastid genome evolution. Furthermore, he is interested in plant evolutionary topics such as phylogenetic inference, biogeography, and the molecular evolution of heterotrophic plants. His work addresses significant biological questions including speciation and character evolution, and he is particularly fascinated by the changes that have shaped plastid genome evolution and patterns of mitochondrial evolution in land plants.
