In February 2018, the German news magazineSpiegel Online published an article about abuse of power by senior scientists at the MPI for Astrophysics. Several emails obtained by BuzzFeed News Germany revealed in June 2018 that the allegations concerned MPA director Guinevere Kauffmann, who was accused of harassing and bullying students and scientists for years. Leaked emails published by BuzzFeed News Germany also include what has been described as racist, sexist and homophobic statements directed at employees and students. Responding to questions by the journal Nature, Kauffmann denied the accusations of racism, sexism and homophobia, claiming that she is merely interested in cultural differences between people and Buzzfeed had made severe errors. She conceded that as a student she was subject to "very high pressure supervision", acknowledging however that such a mentoring style "has now become unacceptable" and claiming to have changed her behavior substantially after complaints were received. This and other cases sparked a general debate about the abuse of power in science.
