The allegations that prompted the investigation include claims, first raised publicly by former Cambridge philosophy researcher Nathan Cofnas, that Arday plagiarised portions of his 2015 PhD thesis. Cambridge said ongoing academic misconduct complaints continue under its research misconduct policy. Arday denied the plagiarism allegations in a Times interview, acknowledging academic "mistakes" while saying he was being subjected to a campaign. Cambridge did not specify what new information prompted Wednesday's announcement. His memoir Great and Unfortunate Things, published by Simon & Schuster's 37 Ink imprint, is due for US release shortly.
