Honey bee health, pollination ecology, and apiculture-related investigations are central to his entomology expert witness practice developed through more than 50 years of academic, consulting, and research experience in entomology and applied ecology. His expertise includes apidology, apiculture, pollination management, queen bee replacement, swarming honey bees, honey bee pests and diseases, colony collapse disorder, integrated pest management, greenhouse insect pests, ornamental insects, urban entomology, wildlife conservation, and beekeeping education and standards. He has 25 years of expert witness experience, including deposition testimony, arbitration matters, and court testimony involving entomology and beekeeping-related issues.

His publications and educational contributions include more than 80 refereed journal articles, multiple books and book chapters, teaching manuals, extension publications, newsletters, and technical articles involving bees, pollination, insect management, and apiculture. He has also conducted international consulting, agricultural development, and beekeeping education projects involving pollination systems, sustainable agriculture, integrated pest management, and beekeeper training programs throughout North America, Central America, South America, and the Caribbean. His educational background includes Bachelor of Science, Master of Science, and Doctor of Philosophy degrees in zoology and entomology. Additional professional activities include grant-supported research initiatives, pollinator protection education, sustainable agriculture programs, and international beekeeping development projects involving training, outreach, and applied entomology research.

He has held senior academic and administrative leadership responsibilities as professor, extension entomologist, department chair, honors professor, and emeritus faculty member in entomology and applied ecology programs. His work included teaching general entomology, apidology, pollination ecology, insect identification, and online beekeeping education courses, along with research involving honey bee predators, pests, integrated pest management, and ornamental insect control. Additional responsibilities included leadership participation within national and international entomology, pollination, and beekeeping organizations, including the Entomological Society of America, Eastern Apicultural Society, International Bee Research Association, Western Apiculture Society, North American Pollinator Protection Task Force, and Honey Bee Health Coalition. His standards and policy-related work included involvement with professional training standards, bee management task forces, pollinator protection initiatives, and development of best management practices for Varroa management and honey bee health.
