LettersUniversity of Michigan must stand up for its Chinese scholars
Readers discuss cases involving researchers at a US university, and the International Olympic Committee’s gender testing requirement

On behalf of California Scholars for Academic Freedom, an organisation of over 200 scholars in higher education in California dedicated to the defence of academic freedom, we would like to draw attention to cases involving Chinese scholars associated with the University of Michigan.
Acclaimed as a brilliant researcher with a bright future ahead of him, Dr Wang’s sudden demise reportedly was preceded by an intensive interrogation session by federal investigators.
We see no indication that the University of Michigan has done much to rectify its lack of support for its Chinese scholars in the face of heavy-handed tactics employed by federal authorities.
We are especially disturbed by the silence of the University of Michigan administration. To our knowledge, an email on Dr Wang’s death was only sent to the College of Engineering over a week after it occurred.
