The University of Cambridge’s vice-chancellor has committed to an independent investigation of Jason Arday’s appointment and tenure at the institution, promising to “learn from any mistakes”.

In her first public remarks since allegations of plagiarism and research misconduct were made against the star sociology professor, Deborah Prentice said the “troubling case” should not be used to undermine other ethnic minority scholars.

Arday resigned on 5 August citing relentless public attention on his work and personal life. He has denied being a “liar” after questions were raised about apparent plagiarism in his doctoral thesis, his claims to hold certain academic positions and his research methods.

Cambridge had already committed to investigating and now Prentice has confirmed this will be carried out independently by senior academics both from within Cambridge and outside the university.

A letter, sent to all staff at the university by Prentice, says she understands the concerns raised by the case “and I share them”.
