Lawrence M. Krauss, a prominent theoretical physicist at Arizona State University, announced on Sunday that he would retire from the university at the end of the academic year after several women accused him of sexual misconduct.

In announcing his departure, Dr. Krauss denounced the university’s investigation, which found that he grabbed a woman’s chest at an event in 2016, and claimed he had been treated unfairly. He has been on paid leave since March and the dean of his department recently recommended that the professor be dismissed from the university.

“To be clear, I have never harassed or assaulted anyone and have most certainly not exhibited gender discrimination in my professional dealings at the university or elsewhere,” Dr. Krauss, 64, who joined Arizona State in 2008, said in a statement on Twitter. “I look to the future for new and different challenges and opportunities.”

He will remain on paid leave, drawing a salary of $265,000, until his retirement in May, the university said. Dr. Krauss said the university had not allowed him to present his side of the story or let him “cross-examine witnesses.”
