The newest member of the University of Virginia Board of Visitors is a longtime political staffer and a former member of the Board of Visitors at James Madison University. Gov. Terry McAuliffe appointed Mark T. Bowles, 55, of Goochland, late last week to replace Dr. Edward D. Miller, a former UVa faculty member who decided to step down one year before the end of his term. Bowles’ term begins June 30.
