MINNEAPOLIS (AP) - The chief information officer at the University of Minnesota has resigned, becoming the second high-ranking administrator to leave in the past month.

University officials aren't saying why R. Scott Studham left. But spokesman Evan Lapiska says there's "no connection whatsoever" to the resignation of athletic director Norwood Teague, who quit amid revelations that he sexually harassed two high-ranking administrators.

Studham says the university is a great place and he learned a lot there, but his passion is elsewhere.

As CIO, Studham oversaw IT operations across the university's five-campus system. He came to Minnesota in 2012 after serving as CIO at Tennessee.

The university announced Thursday that senior associate athletic director Mike Ellis is on voluntary leave while outside lawyers investigate anonymous complaints lodged since Teague's resignation.
