Bill McRaven, University of Texas System Chancellor, announced Dec. 15 that he is resigning in 2018 due to "recent health concerns," according to the UT System.

Following a 37-year career as a decorated military leader, McRaven became chancellor in 2015.

"This decision to transition to private life was one of the hardest I have ever made, but recent health concerns prompted Georgeann and me to reflect on the years ahead and think seriously about things we still want to do as a family," McRaven said in a statement. "While I’m on the road to recovery and am grateful to my UT physicians and the good wishes and prayers of our many friends and colleagues, I believe it is time to segue to several other passions in my life that I’d like to experience, and much of that will also involve teaching and writing."

McRaven has told the Regents that he would be interested in considering an advisory role in the management and operation of the Los Alamos National Laboratory, if the UT System is successful in its bid, currently being reviewed by the Department of Energy’s National Nuclear Security Administration.
