David M. Joyner has been named acting athletic director for Penn State, effective immediately. Joyner, a Penn State Distinguished Alumnus and a member of the Board of Trustees since 2000, will suspend his membership on the board to take on his new role.

"Dave Joyner has served the board with integrity, and he is internationally known for his work with the U.S. Olympic Committee. I am confident that he will bring that same integrity to his new role," said Penn State President Rodney Erickson.

Mark Sherburne has returned to his duties as associate athletic director.

"I would like to thank Mark for filling this leadership role when asked last week. I am grateful for his willingness to do what was needed to move us forward. Now, as he returns to his regular duties, we look for his continued leadership in that role," Erickson said.

Joyner received his bachelor's degree in science from Penn State in 1972 and his M.D. from Penn State's College of Medicine in 1976.

Hershey Medical Center and a brief stint in the World Football League, Joyner began a medical career with a sports medicine emphasis.

He is a member of the board of directors of The Milton S. Hershey Medical Center. Joyner was honored as a Distinguished Alumnus of Penn State in 1992.

His work with the U.S. Olympic Committee includes service as head physician to the United States' teams at the 1992 Olympic Winter Games, the 1991 World University Games and the 1989 United States Olympic Festival.
