Keeton has been interim dean of the medical school for the past seven months. He was also named vice chancellor for health affairs.
Ole Miss Chancellor Dan Jones, who formerly held both positions, says he will submit the names of Keeton and others for posts at the teaching hospital to the state College Board for approval.
Keeton, a professor of surgery and pediatrics, earned his medical degree in 1965 from UMC. He served residencies in urology at UMC and in London.
The Columbus native returned to Mississippi in 1970 after two years in the Navy. He has been in academic medicine and private practice including a stint as Jones’ chief of staff.
