Arboretum Scientists

With state-of-the-art research and growth facilities nestled alongside over 16,000 living specimens (2,100 species), the Arnold Arboretum is uniquely positioned to ask broad and important questions in plant biology. Our scientists’ research is as diverse as our living collection, ranging from organismic and evolutionary biology, molecular and developmental biology, plant physiology, and ecological, environmental and biodiversity studies. Emphasizing our close relationship to the Department of Organismic and Evolutionary Biology (OEB), many of our scientists have dual appointments in OEB and the Arboretum.
