Dr. Elmer serves as Chief Scientist for the Department of Plant Pathology and Ecology. As a plant pathologist, he studies the ecology and control of soilborne fungi that infect crops important to the citizens of Connecticut. He has expertise in the fungal genus Fusarium which contains many species that cause diseases of crops.

Dr. Elmer’s research focused on the ecology of soil borne disease of vegetables and ornamentals. He has authored over 90 research articles. Recent articles are listed below
Dr. Elmer is currently developing strategies to suppress root diseases using combinations of mineral nutrition, soil amendments (biochar), and earthworms. Understanding the mechanisms of suppression and their contributions to soil and plant health is a long term goal. More recently Dr. Elmer has studied the use of nanoparticles of metallic oxides and composites to suppress plant diseases through altering host defense pathways.
