Nathan Cofnas, the American researcher who first publicly detailed extensive plagiarism allegations against Cambridge University’s youngest Black professor, Jason Arday, has said he bore no personal animosity towards the late academic. In his first detailed comments to VRT NWS after Arday’s death, Cofnas stated that he “had zero interest” in Arday as an individual and “no ill will towards him”. He insisted the controversy was fundamentally about diversity, equality and inclusion (DEI) policies at Cambridge and similar institutions. “I set in motion a series of events that led to a tragic outcome, but this was about diversity policy and Cambridge. Arday played only a supporting role in it,” Cofnas said. He added that he had wanted Arday to remain a professor and “live his best life”.
Nathan Cofnas challenges the story behind Jason Arday’s rise at Cambridge
In March 2023, Jason Arday was appointed professor of sociology of education at the University of Cambridge, becoming the institution’s youngest Black professor, and his appointment attracted widespread positive coverage. Central to that coverage was Arday’s account of overcoming extraordinary challenges in his youth. He said he had been diagnosed with autism, global developmental delay, mutism, deafness and dyscalculia, had remained non-verbal until the age of 11 and had only learned to read and write at 18. He also spoke publicly about surviving epilepsy, testicular cancer and a brain tumour. His story of overcoming these difficulties and rising into academia was widely presented as an example of exceptional resilience. However, subsequent scrutiny by The Guardian found that questions extended beyond the allegations concerning his research. Several claims about his academic career and qualifications could not be substantiated. Arday’s biography at Jesus College, Cambridge, stated that he had held visiting professorships at Ohio State University and the University of Glasgow, but Ohio State said he had never been employed there, while Glasgow also denied that he had held the claimed visiting professorship. His biography also described him as an honorary professor at Durham University, although the university said he no longer held any role there. Arday had further stated that he completed a master’s degree in psychodynamic practices at Birkbeck, University of London, and subsequently became a fully qualified counsellor, but Birkbeck told The Guardian that it could not find a record of a student named Jason Arday having studied there.His claim to have authored a book with Palgrave Macmillan was also questioned, with the publisher confirming that it had received a proposal but that the book was never published. These findings became significant because they concerned not merely interpretations of his achievements but specific claims about institutional affiliations, qualifications and publications that could be checked against the records of the organisations named. The scrutiny later expanded to his athletic and charitable claims, including his statements about running 30 marathons in 35 days, completing 600 miles in six days and raising £5 million or more for charity. The Guardian reported that some institutional descriptions of the 600-mile challenge were subsequently amended, while Arday clarified that the feat had actually taken place over 12 days because rest days had been included.
The plagiarism allegations
In mid-July 2026, Nathan Cofnas, a postdoctoral researcher at Ghent University who describes himself as a “racial realist” and critic of DEI policies, published a Substack article titled “DEI Fraud and Cover-Up at Cambridge”. Using plagiarism-detection software, Cofnas argued that numerous passages in Arday’s doctoral thesis and later academic work had been taken from other sources with minimal alteration. He presented the case as evidence of deeper problems with how universities prioritise identity in appointments.The Substack post triggered intense coverage, particularly in British newspapers. Cambridge announced an investigation on 5 August 2026 into Arday’s academic qualifications and honorary appointments. The same day, Arday resigned, stating that the pressure had become too great for his well-being and family, while emphasising that his departure was not an admission of guilt. A week later, on 14 August, Arday was found dead at his home in London at the age of 41. Many on social media and some commentators attributed responsibility for the outcome to Cofnas and the ensuing scrutiny. There is, however, no established evidence in the material provided that Cofnas caused Arday’s death.
Cofnas’s response and suspension
Speaking to VRT NWS, Cofnas acknowledged that his actions set events in motion that ended tragically. He argued, however, that powerful people must remain open to criticism even when it risks causing personal distress. “You have to be able to criticise such people, even if there is a risk that they will misunderstand it or feel very bad about it,” he said. Shortly after Arday’s death, Ghent University suspended Cofnas preventively and opened a preliminary disciplinary investigation, stating that it took his public statements “very seriously”.
Broader controversy
Cofnas remains a polarising figure. He has previously argued that genetic factors play a non-trivial role in average group differences in intelligence, views that contributed to the end of his association with Emmanuel College, Cambridge, in 2024. Supporters see his work on Arday as a necessary defence of academic standards; critics describe it as racially motivated. In the same VRT interview, Cofnas characterised an earlier on-camera remark about heading a future “Department of Eugenics and Race Science at Harvard” as a joke based on his belief that universities should study race and hereditary influences more openly.
