The Graduate School of Genome Science and Technology, offered by UT and ORNL, is a part of the Joint Institute for Biological Sciences. It offers the PhD degree, primarily, but also has a master’s track for some students. It traces its roots to the UT-Oak Ridge Graduate School of Biomedical Sciences, which was approved by the board of trustees on November 5, 1965, and opened the following year to offer a four-year PhD program. The UT-Oak Ridge School of Biomedical Sciences was operated by the UT Graduate School. Its first director, appointed in 1966, was Dr. R. Clinton Fuller, professor of microbiology at the Dartmouth Medical School. The GST graduate school was established in 1998.
