UVA has hired a second Hokie away from Blacksburg as it forms a competing Biocomplexity Initiative. Lauren Coble, chief operating officer of Virginia Tech’s Biocomplexity Institute, will join the institute’s former executive director Chris Barrett in Charlottesville, a UVA spokesman confirmed Wednesday. UVA’s initiative aims to use analytical tools to solve complex medical and societal issues and will work with the planned Bioinformatics Research Institute at the Inova campus in Fairfax.
