LONDON — A British sociologist who became famous as the youngest Black professor ever appointed at the University of Cambridge has resigned after the university said it opened an investigation into “new information” about his academic qualifications.

Professor Jason Arday, who was 37 when he became a Cambridge professor in 2023, announced his decision late Wednesday following weeks of allegations about plagiarism in his academic work and questions surrounding claims he previously made about his athletic and fundraising accomplishments.

“While criticism is an inevitable part of academic life, what I have experienced has gone far beyond scholarly disagreement,” Arday said in a statement released by the Good Law Project, a campaigning legal organization. “The relentless accusations, speculation and public commentary have taken a profound toll on me and on those I love.”

Arday’s appointment at Cambridge underscored his personal story of overcoming dyslexia, developmental delays and autism that he said left him non-verbal until the age of 11 and illiterate until his late teens.

Questions about his qualifications were raised publicly last month by Nathan Cofnas, a one-time Cambridge philosophy researcher who left the university after his criticism of diversity, equity and inclusion policies sparked widespread protests.

On July 24, the Times of London published an analysis of Arday’s 2015 Ph.D. thesis highlighting what it said were multiple examples of passages that were “identical or near-identical” to an earlier paper written by another researcher.

Cambridge initially stood by Arday, saying that the plagiarism allegations had been investigated by Liverpool John Moores University, which awarded Arday’s doctorate.

That changed Wednesday when Cambridge opened its inquiry.

“The University of Cambridge has begun an investigation following new information about Professor Arday’s qualifications and honorary appointments,” the university said in a statement. “In order to ensure a fair process, we will not comment further until this has concluded.

The Times of London said Cambridge decided to investigate after it presented new evidence that some of Arday’s research was “fabricated” and contained “impossible” evidence.

In an interview with the newspaper published last week, Arday denied plagiarism but admitted to some mistakes that he said were partly due to a lack of supervision when he was working on his doctorate.

Arday continued to defend himself in his resignation statement, saying his decision “should not be interpreted as a loss of faith in scholarship.”

“Nor should it be mistaken for an acceptance of the narratives that have surrounded me’” he said. “It is simply the decision of someone who has reached the limits of what any person should reasonably be expected to endure.”
