Bio
Dr. Tudge is a reproductive biologist with particular interests in the reproductive biology of invertebrates. His research focuses on the reproductive cells and associated structures, evolutionary mechanisms, and reproductive behaviors of marine decapod crustaceans (shrimps, crabs, crayfish and lobsters). He also has experience dealing with other invertebrate and vertebrate groups and his knowledge of reproduction in crustaceans can be directly applied to other taxa. He uses this interest in crustacean reproduction to investigate the evolutionary history (phylogeny) of particular crabs in the marine environment and his work has direct application to aquaculture of commercial species and conservation of marine and freshwater crustaceans. Dr. Tudge is also a keen local natural historian and bird biologist and teaches classes on ornithology, marine biology and marine mammals. He is affiliated faculty in the Department of Environmental Studies at AU and routinely has undergraduate independent research projects and graduate research projects in both biology and environmental studies. Some of the projects his recent MS students have undertaken include studying coyotes in Washington, DC, invertebrate ecosystems in urban environments, captive songbirds and migratory restlessness, and food resource use in mantled howler monkeys. Dr. Tudge has an active research affiliation with the Smithsonian Institution in Washington DC and numerous contacts in local county and state parks where research projects have occurred. He currently has active research collaborations in Brazil and Iran.

Additional Information

Christopher Tudge has published more than 70 papers in international scientific journals on aspects of crustacean ecology, evolution, and reproduction with colleagues at the Smithsonian Institution and with coauthors in Australia, Japan, France, Argentina, Italy, Brazil and Iran. He is a current member, and was the past President, of the Crustacean Society, an international society of crustacean biologists. He is also an active member of the Brazilian Crustacean Society and the International Society for Invertebrate Reproduction and Development. Tudge has presented talks or posters, or chaired sessions, on crustacean reproductive morphology and evolution at more than 50 national and international venues. He is a Research Associate in the Department of Invertebrate Zoology at the National Museum of Natural History of the Smithsonian Institution, is the current Editor-in-Chief for the crustacean journal Nauplius, and is on the Editorial Board of the Iranian Journal of Animal Diversity. Tudge has recently described and named several new species of marine mud shrimp from the Gulf waters of Iran and he has a hermit crab species named for him, which he discovered as new to science on a reef in Belize.
