Rate My Professor William Etges

William Etges is a Professor Emeritus in the Department of Biological Sciences at the University of Arkansas at Fayetteville, contributing to the field of Biology through his expertise in evolutionary biology. He received his B.S. cum laude in Zoology from North Carolina State University in 1976, M.Sc. in Zoology from the University of Georgia in 1979, and Ph.D. in Biology from the University of Rochester in 1984, where he held an NIH Predoctoral Fellowship from 1980 to 1983. Following his doctorate, Etges served as a Visiting Assistant Professor and NSF Postdoctoral Fellow in the Department of Ecology and Evolutionary Biology at the University of Arizona from 1984 to 1987. He joined the University of Arkansas in 1987 as an Assistant Professor, advancing to Associate Professor and then Full Professor, a position he holds to the present alongside his emeritus status. Additional appointments include a Cambridge Research Fellowship in the Department of Genetics and Wolfson College at the University of Cambridge in 2007-2008, and a Savannah River Ecology Laboratory Summer Research Fellowship from 1977 to 1979.

Etges' research program in the Etges Lab investigates evolutionary genomics, with a focus on adaptation, life history evolution, speciation biology, chemical ecology, sexual isolation, and systematics, primarily using cactophilic Drosophila species such as Drosophila mojavensis and their host plant interactions. Employing ecological, physiological, genetic, and genomic methods in field and experimental studies, his work elucidates mechanisms generating biological diversity. Key publications include 'Ecological divergence exhibits consistently positive associations with reproductive isolation across disparate taxa' (Proceedings of the National Academy of Sciences, 2006; 519 citations), 'Premating isolation is determined by larval rearing substrates in cactophilic Drosophila mojavensis. III. Epicuticular hydrocarbon variation' (Journal of Chemical Ecology, 1997), and 'Genetics of incipient speciation in Drosophila mojavensis. I. Male courtship song' (Evolution, 2007). He edited the volume Genetics of Mate Choice: From Sexual Selection to Sexual Isolation (Kluwer Academic Publishers, 2003) and organized a symposium on the genetic basis of sexual selection and speciation. Etges has mentored over 20 graduate students to M.S. and Ph.D. degrees, as well as numerous undergraduates through NSF REU programs and honors theses, many of whom pursued advanced careers in academia. His contributions have advanced understanding of reproductive isolation and ecological adaptation in Drosophila, evidenced by highly cited papers influencing speciation research.
