Dr. Rosenberger joined Olivet's full-time faculty in 2016. He teaches courses in invertebrate zoology, animal behavior, vertebrate natural history and anatomy, tropical and arctic field biology (Costa Rica and Alaska), and general biological science. His area of specialty is forest entomology and conservation biology.
He has been working in higher education since 2007 and has taught courses at Taylor University, Bethel University and Wheaton College Science Station. Supervising research experiences for undergraduate students is one of his most exciting pursuits. One of his students won first place at a national meeting for their collaborative research on insect-fungal symbiosis.
He has led multiple international service-learning trips to Central America and been involved in educational programs in Belize, New Zealand and India. He lived in Belize for three years, where he directed and taught in the Creation Care program, a study abroad program focusing on integrating faith, sustainable development and ecology.
His research on the effects of new host plants on the behavior and ecophysiology of the mountain pine beetle, based in the Black Hills of South Dakota, is ongoing with researchers at the University of Minnesota and USDA Forest Service. His research has covered topics ranging from microbial symbionts of the mountain pine beetle to insect-plant chemical ecology to woodpecker foraging behavior to invasive species risk assessment. Dr. Rosenberger has presented his research at several international conferences and many regional and national meetings.
In 2015, Dr. Rosenberger won the first place President's Award at the national meeting of the Entomological Society of America for his research presentation on insect cold tolerance. His research publications have focused on both forest entomology and science pedagogy in higher education. He is a member of the Entomological Society of America and Society for Conservation Biology.
Outside the classroom and office, he enjoys birding and has taken multiple trips in the United States, Central America, India, New Zealand and Argentina. He also loves reading books to his children, gardening and nature photography.
Dr. Rosenberger is married to Ashley, who has a master's degree in environmental science. They are the parents of two young boys, Isaac and Nehemiah, who study anything that lives under a rock — and would be happy to share their "research" with you!
