Spencer Barrett (evolutionary biologist)

Barrett attended University of Reading in England for his undergraduate education. ==Research and career==

Barrett's interests are in evolutionary biology, evolutionary genetics, evolutionary ecology and plant reproduction. the flagship scientific journal in the biological sciences of the Royal Society. Barrett is an evolutionary biologist and a worldwide authority on the ecology and genetics of plant reproduction. His work has focused on increasing understanding of how flowers evolve and the mechanisms responsible for mating system transitions in flowering plants. Barrett provided the first experimental evidence for the purging of deleterious genes following inbreeding in plants. He also demonstrated that self-fertilization owing to large floral displays in plants can have a detrimental effect on the male fertility of plants. Barrett's research group at the University of Toronto focuses on understanding the mechanisms responsible for the evolution of plant mating strategies, and he has edited several leading books in the field. ==Awards and honours==
