The woman who served as former University of Illinois President Michael Hogan's chief of staff has resigned a faculty job.

The university said Tuesday that Lisa Troyer has resigned her tenured psychology professor's position and will be paid $175,000 as part of a separation agreement.

Troyer was a key figure in the dispute with faculty that led Hogan to resign in March.

Last December anonymous emails were sent to faculty leaders aimed at swaying their opposition to an enrollment management plan that Hogan favored. Those emails were eventually traced to Troyer's computer.

Troyer on Tuesday issued a statement through an attorney denying she sent them.

Troyer resigned as chief of staff in January and took the $109,000-a-year faculty job.

Hogan is now a professor at the university.
