Former University of Minnesota Chief Information Officer Scott Studham resigned from his position last week after President Eric Kaler asked him to step down.

The University has received four reports about Studham’s conduct since May. The complaints allege that he used University funding for personal expenses, was unfair in hiring decisions and misused his travel expenses and vacation days.

 “While there have been complaints filed with the University about Mr. Studham’s judgment, that’s not the reason I requested that he step aside,” Kaler said in a written statement. “My decision centered on the culture in his unit and his relationship with his peers.”

Studham — who began working for the University in 2012 — disputes the allegations.  In a letter released by the University, he said the claims against him were misunderstandings and “simply untrue”.
