Scientists and staff

The Morton Arboretum’s scientists are distinguished researchers in fields related to the biology, planting, care, and conservation of trees. Working with collaborators from around the world, they present their findings to public and professional audiences, through conferences, prestigious scientific journals, and presentations throughout the community. Arborists, horticulturists, landscape designers, natural area stewards, public officials, and home gardeners all benefit from their knowledge and expertise. The Arboretum’s research programs all support its basic mission: to encourage the planting and conservation of trees and other plants for a greener, healthier, and more beautiful world.
