Two institutional investigations that concluded in 2016 and 2019 found scientific misconduct in multiple publications from the lab of a leading urologist at the University of California, San Francisco, Retraction Watch has learned. 

The investigations could not determine who had manipulated the published images of experimental data, but the 2019 report concluded that Rajvir Dahiya, also director of the urology research center at the San Francisco Veterans Affairs Medical Center, “was senior/last author on all these publications and therefore responsible for the results.” Dahiya retired in 2020. 

The two investigation reports, which we obtained through a public records request, along with the reports from the preliminary inquiries preceding the investigations, recommend notifying the journals that published eight papers of the issues identified. Four have so far been retracted, one corrected, and two marked with expressions of concern. One of those expressions of concern was published last month. 

In comments to Retraction Watch, Dahiya blamed the findings that research misconduct occurred in his lab on the age of the papers. He said the VA destroyed notebooks with original data that had been stored in a central facility after the required data retention period had lapsed: 

One of the world’s foremost conservation biologists is being accused of plagiarism and bullying by a former PhD student, Retraction Watch has learned.  

The biologist, Stuart Pimm of Duke University, strongly denies the charges, but he and his colleagues have acknowledged the existence of “closely related” work following an internal investigation by Duke.

The allegations surfaced late last month on X, formerly known as Twitter, in a thread that quickly went viral, garnering hundreds of thousands of views and drawing comments from a broad swath of scientists. 

In the thread, Ruben Dario Palacio claimed his former academic advisor “threatened to kick me out of Duke” to make him work faster. Palacio decided to change labs due to the alleged “bullying and harassment,” he said, and three months later, in April 2020, published his research as a preprint. The article appeared in the journal Diversity and Distributions in October 2021.

A researcher and former faculty member at Tufts School of Medicine in Boston has been banned from working with animals for a year following repeated cases of abuse under his supervision, according to documents obtained by an animal-rights group.

In an Oct. 26, 2022, letter to the federal Office of Laboratory Animal Welfare, the university reported “serious and continuing noncompliance with” animal-welfare regulations. These breaches included “injections in mice via an unapproved route/location, failure to provide required analgesia, inadequate supportive care and monitoring, and failure to euthanize mice upon reaching the approved humane endpoints,” Tufts said.

When asked for his comments, the researcher “refuted most of the allegations and took no responsibility for his actions,” the university added.
