Norman and Doris Giles Professor Georgia Research Alliance Eminent Scholar Ph.D. (1980) University of Washington Member, National Academy of Sciences 1000 Talents Award, Chinese Academy of Sciences, 2012 Guggenheim Fellow, 2008 Elected Fellow, American Association for the Advancement of Science, 2005 Grant Support - Sequencing of the Aegilops tauschii Genome, NSF “Analysis of the Genetic and Environmental Inputs into Accurate and Inaccurate Double Strand Break Repair in Plants," NSF "Molecular Analysis of Unequal Recombination and Instability at the Pc Toxin Susceptibility Locus," USDA-NIFA Bioenergy Science Center, DOE "Unraveling the Genetics of Two Key Biomass Traits that Differentiate Upland and Lowland Tetraploid Switchgrass Ecotypes, Colonization by Mycorrhizal Fungi and Frost Tolerance," DOE Research Interests - My lab is interested in plant genome structure and evolution, especially the nature of rearrangements and the contributions of transposable elements. We also study the relationship between genome structure, evolution and gene function. We have long-standing interestes in genetic diversity and its use in under-utilized crops of the developing world, the rapid evolution of complex disease resistance loci in plants, fine structure recombinational analysis, epigenetic gene regulation, biomass improvement for bioenergy, and the coevolution of plant/microbe and plant/parasite interactions.
