Na Wei successfully defended her doctoral dissertation (and with flying colors!) on April 14, 2015. Her dissertation, entitled GENE DISPERSAL IN TROPICAL TREES: ECOLOGICAL PROCESSES AND GENETIC CONSEQUENCES involved detailed population genetic studies of four tree species on Barro Colorado Island. Na did extensive genetic marker development, mathematical modeling and grueling fieldwork, with an overall goal of understanding how seed and pollen movement differentially contribute to gene flow (and genetic structure) in tropical trees. Na has already published 4 papers (with a fifth in revision) and has several larger papers in the pipeline. Excellent work Na!
