Allison Snow’s Plant Population Ecology Lab studies natural selection and ecological processes within plant populations, including the dynamics of gene flow, especially involving transgenic plants. Trained as a plant ecologist at the University of Massachusetts, Snow received postdoctoral fellowships from the National Science Foundation and the Smithsonian Institution. Her current research combines molecular and ecological approaches to understand how quickly crop genes move into wild populations, and the extent to which novel transgenic traits could benefit weedy and semi-weedy plants. She is the lead author of a 2005 Ecological Society of America position paper on environmental effects of genetically engineered organisms. A fellow of the American Association for the Advancement of Science and the Aldo Leopold Leadership Program, she has served on the editorial boards of Ecology, Ecological Monographs, Evolution and Environmental Biosafety Research. A past president of the Botanical Society of America, she has served on the U.S. Department of Agriculture’s National Genetic Resources Advisory Board and panels convened to discuss issues in transgenic organisms by the National Research Council and the Academy of Finland. In 2002, she was one of Scientific American’s Top 50 Researchers in Science and Technology. She also directs the Undergraduate Research Office at Ohio State.
