John Avise

John Charles Avise (born 1948) is an American evolutionary geneticist, conservationist, ecologist and natural historian. He is a Distinguished Professor of Ecology & Evolution, University of California, Irvine, and was previously a Distinguished Professor of Genetics at the University of Georgia.

Born in Grand Rapids, Michigan, he received his B.S. in 1970 in Natural Resources from the University of Michigan; his M.A.in 1971 in Zoology from the University of Texas at Austin; and his Ph.D. in 1975 in Genetics from the University of California, Davis. Avise's research entails the use of molecular markers to analyze ecological, behavioral, and evolutionary processes in nature. It covers a broad spectrum of topics: genetic parentage, reproductive modes, population structure, speciation, hybridization, introgression, phylogeography, systematics, and phylogenetics. He has conducted research on diverse animal taxa ranging from corals and sponges to representatives of all the major vertebrate groups.
