Professor of Population Genetics
Charles ("Chip") Aquadro is the Charles A. Alexander Professor of Biological Sciences, and Professor of Population Genetics in the Department of Molecular Biology and Genetics, with a joint appointment in the Department of Ecology and Evolutionary Biology, and is the Director of the Cornell Center for Comparative and Population Genomics. He received a B.S. in Biology at St. Lawrence University in 1975, an M.S. in Zoology at the University of Vermont in 1978 (with C.W. Kilpatrick) and a Ph.D. in Genetics at the University of Georgia in 1981 (with J.C. Avise). Prior to joining the Cornell faculty in 1985, he was a member of the Laboratory of Genetics with C.H. Langley at the National Institute of Environmental Health Sciences (NIH). He currently serves on the Council of the Society of Molecular Biology and Evolution, has served as Associate Editor for “Molecular Biology and Evolution” and “Evolution”, on the editorial board for “Genome Research”, and on numerous NIH proposal review panels. A founding member of the Cornell Genomics Initiative in 1997, he chaired the Evolutionary Genomics and the Computational and Statistical Genomics focus groups, served as a member of the Provost's Life Science Advisory Council, and chaired the Department of Molecular Biology and Genetics from 2004-2007. He was elected Fellow of the American Association for the Advancement of Science in 1993, and selected as the Genetics Society of Australia's "Society Visitor" for 1994. From 1998-2001, he was a member of the Scientific Advisory Board for the seven show PBS TV series, "Evolution", with WGBH/NOVA (www.pbs.org/evolution). Aquadro's research has been supported by the National Institutes of Health, the National Science Foundation, the USDA, and the Alfred P. Sloan Foundation. He is a member of the graduate fields of Genetics and Development, and Ecology and Evolutionary Biology. He currently teaches Population Genetics, Personalized Genomics, and contributes to teaching Problems in Genetics and Development.
Our research efforts are aimed at discovering the principles and processes that determine the nature, amount, distribution, and functional significance of genetic variation within and between natural populations and among related species. We draw on the tools of experimental and theoretical population genetics, molecular evolution, and comparative genomics to study the structure and evolution of the genome, natural populations, to resolve the evolutionary forces acting on individual genes, and to functionally annotate the genome (particularly that of Drosophila). Our work includes experimental studies of sequence variation and gene structure and function, as well as the development and refinement of statistical and computational methods for detecting selection on synonymous sites, distinguishing natural selection from population demography, and for detecting molecular coevolution (the statistical and computational studies in collaboration with Carlos Bustamante, Rasmus Nielsen and Rick Durrett). Current work focuses on the molecular genetic basis of adaptation in insects, mammals and plants, the functional significance of synonymous (“silent”) variation, the genomic distribution of recombination and its influence on levels and the genomic and geographic distribution of DNA sequence variation, and on the use of evolutionary diversification to understand molecular and evolutionary processes that modulate fertilization and regulate germ line stem cell maintenance and differentiation in Drosophila.
