A professor at the University of Cambridge is facing fresh scrutiny after reports alleged that he falsely claimed academic positions at three universities, adding to an ongoing controversy surrounding accusations that parts of his Ph.D. thesis were plagiarized. 

The allegations involve Professor Jason Arday, who has been accused of copying more than 100 passages in his doctoral dissertation from another academic's work. He also allegedly misrepresented his affiliations with Ohio State University, University of Glasgow and Durham University.

According to the reports, Ohio State said it had no record of employing Arday, Glasgow said he had worked there previously but was never a visiting professor after leaving, while Durham said he only held an unpaid academic association. 

The plagiarism claims first emerged after independent researchers and media reports questioned similarities between Arday's Ph.D. thesis and another dissertation. However, Liverpool John Moores University, where he earned his doctorate, previously investigated the allegations and said it found no evidence of plagiarism or academic misconduct. 

The University of Cambridge initially defended Arday, describing the earlier accusations as part of a coordinated campaign against him. However, following new allegations concerning his academic qualifications and résumé, the university has opened a fresh investigation into the matter. 

Arday has denied wrongdoing, maintaining that previous investigations cleared him of misconduct. He has acknowledged making some mistakes but rejects claims that he deliberately fabricated his academic record or plagiarized his work. 

The controversy has sparked wider debate within British academia about research integrity, transparency and the importance of verifying academic credentials, particularly for scholars in high-profile positions.
