The battle over the fate of Harvard’s president, Claudine Gay, took an unexpected turn this week, as questions surfaced not just about her handling of antisemitism on campus but about her academic work as well.

In a statement Tuesday announcing that Dr. Gay would stay in office, Harvard’s governing board said that after receiving accusations in October about three articles written by the president, it had initiated an independent review and determined that she had not violated the university’s standards for “research misconduct.”

But the Harvard Corporation said its investigation “revealed a few instances of inadequate citation,” adding that Dr. Gay would request “four corrections in two articles to insert citations and quotation marks that were omitted from the original publications.”

In a statement on Monday morning, Dr. Gay strongly defended her work. “I stand by the integrity of my scholarship,” she said. “Throughout my career, I have worked to ensure my scholarship adheres to the highest academic standards.”

Harvard’s support is unlikely to end the turmoil around Dr. Gay’s tenure. Representative Elise Stefanik, a Republican who sharply questioned Dr. Gay last week during congressional hearings on antisemitism, criticized the decision to allow her to keep her job.

“The only update to the code of conduct is to allow a plagiarist as the president of Harvard,” she said during a news conference on Tuesday.
