After a month-long investigation into allegations of sexual misconduct and verbal abuse, Pulitzer-prize-winning author Junot Diaz has been cleared by M.I.T. to continue teaching there next year.The writer, whose star has been ascending since his literary debut in 1996, withdrew from the public eye last month after being confronted by Zinzi Clemmons, an author who said Diaz cornered her in a stairwell and "forcibly kissed" her. The incident, according to Clemmons, had taken place years earlier when she was a 26-year-old graduate student. She accused the celebrated Dominican writer this year while they were both attending a literary festival in Australia, and later over Twitter."I'm far from the only one he's done this 2. I refuse to be silent anymore," she wrote.Clemmons' account gained immediate traction online, and other writers added their own alleged experiences of verbal abuse altercations with Diaz. Carmen Maria Machado and Monica Byrne both recounted experiences that were not physical in nature but still violent and misogynistic, they claimed.After scandal had been set off, Diaz acknowledged some inappropriate behavior without addressing any of the specific accusations."I take responsibility for my past," he said vaguely in a statement provided through his literary agent to The New York Times. "I am listening to and learning from women's stories in this essential and overdue cultural movement. We must continue to teach all men about consent and boundaries."The stories prompted MIT to launch an investigation into Diaz's behavior as a professor and his conduct toward women at the school.As NPR member station WBUR reported on Monday, the university announced it had concluded its investigation into Díaz and found no evidence of wrongdoing.
