Included in the article are a few quotes from Prof. Harran:
Sangji's supervisor, professor Patrick Harran, says that he did address the PPE issues with his group. "My expectation is that everyone is to wear a lab coat and wear protective gear on their eyes," he says, adding that a lab coat is specifically ordered for everyone who joins the group. He refused to speculate as to why Sangji was not wearing her coat on the day of the accident. The two postdoctoral researchers who were in the lab with her were both wearing their lab coats, Harran says. [later in the article...] Regarding Sangji's training to handle tert-butyllithium, "She was supervised by senior personnel in my lab and shown how to do this particular procedure. She repeated it successfully," Harran says.
