In another e-mail sent Jan. 15, 2007, Rogoff wrote that “Given all that has happened recently, and that you now have other places to go for advice and advising, perhaps it would make sense if you do not write for an extended period.”

According to the e-mail logs, GSAS Dean for Students Garth O. McCavana wrote to Gu that further contact with Rogoff “could be construed as harassment and could end you up in trouble.”

Gu continued sending a series of e-mails to Rogoff from both her FAS account and an anonymous Gmail account, based on her logs.

According to the e-mails posted on Gu’s site, she was referred to University Health Services Chief of Mental Health Richard D. Kadison for “inappropriate and intrusive” behavior in June 2007 and was placed on involuntary medical leave in Aug. 2007 for a pattern of behavior that was “extremely disruptive to the academic environment.” Gu said she was required to leave the United States within two weeks.

In Aug. 2009, the Administrative Board of GSAS recommended against Gu returning to continue her studies, and Gu was required to withdraw, she said.

Students who accessed the e-mail logs expressed concerns about the accuracy of Gu’s portrayal.

“I felt that in many ways, how she portrayed herself [in the e-mail sent to students] was very different from how the reality might have been,” said Steve Teng ’10. “In some ways, I think she definitely crossed the line between personal and professional.”

A current Harvard graduate student who asked to remain anonymous because they did not want to compromise relationships with faculty members said that they could sympathize with Gu’s situation.

“I think the power balance for international graduate students is a little different,” the grad student said. “I don’t think the department acted at all inappropriately, but because she was an international student, the department held an enormous amount of power over her in the sense that they forced her to leave the country immediately.”

Friday’s e-mail was not the first time Gu had e-mailed allegations to Harvard students. According to the e-mail log on Gu’s site, she sent a series of e-mails to current and former students in the economics department in Aug. 2008. The e-mails contained allegations about both faculty and students in the department.
