Dr. Humphrey joined the Biology Department at Aquinas College in 2016. Her primary research interests are the evolution of sexual dimorphism in plants and the evolution of pollen grain morphology in response to shifts between wind and insect pollination. Dr. Humphrey is also interested in service learning, sustainability, and innovative teaching strategies.  Dr. Humphrey teaches courses related to Evolution, Botany, and Ecology as well as courses in the introductory series. Outside of work, Dr. Humphrey is an avid yogi and a dog owner.
