The Office of Research Integrity has thrown a heavy book at Bengu Sezen, a former chemist at Columbia University, alleging that school and agency investigators turned up 21 instances of research misconduct by the disgraced scientist.
Anil Potti, who resigned from his post at Duke today during an investigation into faked results, will likely have another retraction to his credit shortly. According to a Duke statement:
Dr. Potti’s collaborator, Joseph Nevins, Ph.D., has initiated a process intended to lead to a retraction request regarding a paper previously published in Nature Medicine. This process has been initiated due to concerns about the reproducibility of reported predictors, and their possible effect on the overall conclusions in this paper. Other papers published based on this science are currently being reviewed for any concerns. Continue reading Another update on Anil Potti: Co-author asks Nature Medicine to retract paper
…stepped down from his position at Duke’s Institute for Genome Sciences and Policy Friday and took responsibility for the problems in his research, IGSP Director Huntington Willard wrote in an e-mail to IGSP staff.
Willard wrote that Potti “accepted full responsibility for a series of anomalies in data handling, analysis and management that have come under scrutiny in the past months.”
He said that investigations into Potti’s research will continue, as will IGSP’s examinations of Potti’s science.
a Duke researcher who posed as a Rhodes Scholar and appears to have invented key statistical analyses in a study of how breast cancer responds to chemotherapy[.The case] has sent ripples of angst through the cancer community. Potti’s antics prompted editors of The Lancet Oncology to issue an “expression of concern” — a Britishism that might be better expressed as “Holy Shit!” — about the validity of a 2007 paper in their journal by Potti and others.
There hasn’t been any further movement on The Lancet Oncology study, as far as we know, but on Friday the Raleigh News & Observerreported that one of Potti’s co-authors on a 2007 Journal of Clinical Oncology (JCO) paper had requested a retraction: Continue reading A retraction in the Potti case?
Yesterday, we noted that Axel Ullrich, a decorated cancer researcher, had retracted two papers in the Journal of Biological Chemistry. The journal gave no explanation for the retractions, and our conversation with the publication director for the American Society for Biochemistry and Molecular Biology, which puts out the journal, was less than illuminating. This morning, Ullrich responded to all of the questions we sent him by email, and our follow-ups. The picture is now a lot more clear.
