George Hamilton, professor and extension specialist, retired from Rutgers on January 1, 2026.
Effective January 1, George Hamilton GSNB’85, extension specialist in pest management and professor in the Department of Entomology, retired from Rutgers University, concluding a distinguished 38-year career marked by excellence in extension, research, teaching and service to the university and the agricultural community.
A member of the faculty since 1987, Hamilton made significant contributions to the fields of entomology, pesticide safety education, and the management of invasive insects affecting agriculture in New Jersey. He served as chair of the Department of Entomology for 15 years and held numerous university and statewide advisory roles related to pesticide regulation, environmental protection and agricultural policy.
Trained as an environmental biologist and entomologist, Hamilton earned his doctoral degree in entomology from Rutgers in 1985. Over the course of his career, he authored more than 200 research and extension publications addressing integrated pest management, pesticide use and environmental protection.
Through his work with Rutgers Cooperative Extension, Hamilton became widely recognized for advancing pesticide safety education and integrated pest management programs that support New Jersey’s agricultural industries while protecting environmental and public health. His extension efforts reached thousands of growers, professionals and residents each year through workshops, training programs and outreach presentations.
Among his many contributions, Hamilton played a key role in statewide and national efforts to manage the invasive brown marmorated stink bug, a pest that threatens fruit, vegetable and specialty crops. His research helped improve monitoring and management strategies and contributed to multi-state integrated pest management initiatives aimed at reducing the pest’s impact on agriculture.
He also led and supported the development of integrated pest management programs for a range of crops in New Jersey, including tree fruit, vegetables, blueberries and field crops. These programs helped growers reduce pesticide use while maintaining crop productivity and environmental stewardship.
Nationally, Hamilton was an active leader in the Entomological Society of America, serving as treasurer and president of the Eastern Branch and completing two terms on the ESA Board of Governors.
During his career, Hamilton received numerous state, national and international honors, including awards from the ESA and the U.S. Department of Agriculture recognizing his contributions to research, extension and integrated pest management programs.
