CHATTANOOGA, TN (WRCB) -- After seven years as chancellor of the University of Tennessee at Chattanooga, Chancellor Roger Brown announced his decision to retire, effective September 30, 2012.  

Brown previously announced in June he would remain in the position until a new chancellor could be identified, but he said he has reconsidered that plan.

In a letter to University of Tennessee President Joe DiPietro, Brown explained his reason to leave earlier than originally planned.

University of Tennessee President Joe DiPietro named Dr. Grady Bogue to serve as interim chancellor at UT Chattanooga. His first day on the job will be Thursday, September 20.  

Bogue was a professor of leadership and policy studies at the University of Tennessee, Knoxville from 1991 until his retirement earlier this year. He was chancellor of Louisiana State University in Shreveport from 1980-1991, interim chancellor for one year at Louisiana State University in Baton Rouge, and named chancellor emeritus of LSU Shreveport by the LSU Board of Trustees in 1991.

Bogue was chief academic officer for the Tennessee Higher Education Commission from 1974 to 1980. Prior to joining THEC, Bogue was on the administrative staff at the University of Memphis for ten years.
