James R. Ramsey, the university's 17th president, continued the endowment and fundraising growth started by Shumaker. However, Ramsey added more emphasis on improving the physical aspects of the Belknap Campus. To this end, he started a million-dollar "campus beautification project" which painted six overpasses on the Belknap Campus with a University of Louisville theme and planted over 500 trees along campus streets, and doubled the number of on-campus housing units. The university's federal research funding also doubled under Ramsey, and three buildings were built for nanotechnology and medical research. The university's graduation rate also increased from 30 percent in 1999 to 52 percent in 2012.
