It would be pretty dumb for the other two faculty members to do exactly what the email suggested and I wouldn’t think Duke has so many dumb professors in one single department. Based on the emails she sent, this former director had issues with Chinese students talking loud in Chinese for some time (at least a year), and she’s proven to be less than astute. Besides, the medical school dean didn’t mention the other two faculty members in her letter or take any action against them.
