Brian Guthrie was named executive director of Texas Teacher Retirement System, Austin, effective Sept. 1, confirmed spokesman Howard Goldman.
Mr. Guthrie, the current deputy director of the $105 billion system, replaces Ronnie Jung.
In April 2010, Mr. Jung announced his intention to step down. After Mr. Guthrie starts his new job, Mr. Jung will remain as executive liaison to the board of trustees during a transition period through Jan. 31, 2012.
Whether there will be search for a deputy director has yet to be determined, according to Mr. Goldman.
