- My research focuses on the biology, systematics, behavior, ecology and ultrastructure of insects and other arthropods. While arthropods are my principal research interest, I have also worked with the arthropods associated with bats and pines. Many of my research projects (and those of my students) are strongly field-oriented and carried out in the Coastal Plain of Georgia.

- Beginning Spring 1999, in collaboration with George A. Rogers (GSU) and Frankie Snow (South Georgia College, Douglas) - we began examining the plant-insect interactions of the insect/ arthropod pollinators of the many threatened or endangered species of plants at Broxton Rocks NP.
- In collaboration with Wayne
A. Berisford, Dept. of Entomology, University of
Georgia, we conducted a study of the biological and chemical control of
the Nantucket Pine-Tip Moths, Rhyacionia spp. (Lepidoptera: Tortricidae)
of Loblolly Pines (Pinus taeda) in the Coastal Plain of Georgia. The
project's purpose was to increase the fiber yields of

Graduate Students Return to Dan Hagan's Home Page
Students in my lab have worked on a variety of ecological projects. Generally students have good field skills gained from work or field-oriented courses. Students often are funded either through graduate teaching assistantships or research assistantships paid by my grants. In recent years, students have been generously supported by the Georgia Consortium for Technological Competitiveness in Pulp and Paper; Georgia Department of Natural Resources, Wildlife Resources Division, Nongame-Endangered Wildlife Grants Program; Glynn County (GA) Commission; Hampton Plantation and Golf Course, St. Simons Island, Ga.; Sapelo Island Research Foundation; University of Georgia, Veterinary Medical Experiment Station Grant; U.S. Coast Guard; U.S. Dept. of Commerce/ Sea Grant Program and The Nature Conservancy.
I have served as major professor for sixteen (16) students who have successfully completed the M.S. in Biology degree. See the list below:

Teaching - (photos) Return to Dan Hagan's Home Page
I teach/ have taught formal courses in field biology, entomology, comparative animal physiology, biology of aging, as well as undergraduate/ graduate seminars on various aspects of biology.
This course is an introduction to the role insects and other arthropods serve in relation to humans. Insect human interactions in the home, yard, garden, workplace, recreational areas, and human body are included. Consideration of the natural history, life cycles and optional human actions regarding pests, beneficial insects, insects and disease, insects and food, and aesthetics.
This course is a field introduction to the natural history of plants and animals of the Georgia Coastal Plain. Field collections and observations are integrated with laboratory identification and lectures.
Comparative Animal Physiology, BIOL 5230
