Yannick Griep, a former rising star in management research at Radboud University in the Netherlands, is set to lose an undisclosed number of articles from a journal he once edited, Retraction Watch has learned.
In an email we obtained, Sage’s Isabella Austin told editorial board members of Group & Organization Management that following “a thorough investigation into the concerns about peer-review on this journal,” the publisher found the “objectivity of the peer-review process administered by the former Editor in Chief on a subset of articles where they are co-author was compromised.” Those articles, wrote Austin, would be retracted.
“[N]o determination has been made regarding the scientific content of the articles,” she added.
Griep was fired in late 2024 by Radboud after the university found he had submitted a fake expense report. Attention soon turned to his research, and Radboud determined earlier this year that in one study – now retracted – “roughly half of the data points appeared multiple times and likely originated from a master’s thesis about an entirely different study,” Voxweb.nl reported.
Griep had committed a “very serious violation of scientific integrity,” said Radboud, which has also opened another investigation into more of his work. He is no longer editor in chief of Group & Organization Management, which lists 25 papers with him as co-author.
Sage would not provide Retraction Watch with a list of the articles to be retracted, saying the matter was still under investigation.
