Scientists and staff

Scientists at The Morton Arboretum
The Morton Arboretum’s scientists are distinguished researchers in fields related to the biology, planting, care and conservation of trees. Working in collaboration with research associates at the Arboretum and around the world, they present their findings to public and professional audiences, as well as in conferences and prestigious scientific journals. Arborists, horticulturists, landscape designers, natural lands stewards, public officials, and home gardeners all benefit from their knowledge and up-to-the-minute 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.
