Geoffrey Marcy, the renowned astronomer who was found guilty in a campus investigation of sexually harassing students, is resigning from the faculty of the University of California, Berkeley, where he has been a professor for 16 years.

In an email to members of the astronomy department on Wednesday, the interim chairman of the department, Gibor Basri, wrote, “This is to inform our community that Geoff has initiated the process that will lead to his no longer being a faculty member at U.C. Berkeley.”

In a statement announcing Dr. Marcy’s resignation, the university’s chancellor, Nicholas B. Dirks, and the executive vice chancellor and provost, Claude Steele, said they had accepted Dr. Marcy’s resignation and added: “We want to state unequivocally that Professor Marcy’s conduct, as determined by the investigation, was contemptible and inexcusable. We also want to express our sympathy to the women who were victimized, and we deeply regret the pain they have suffered.”

Dr. Marcy did not respond to a request for comment.

The university placed Dr. Marcy on probation over the summer after the investigation but did not announce the decision. It became widely known only last week.
