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. In an email Retraction Watch 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.”

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.
