with 22 comments

ori logoA former Vanderbilt University biomedical engineer committed fraud on a massive scale, according to a new Office of Research Integrity (ORI) report.

Igor Dzhura is banned from receiving federal funding for three years, and is retracting six papers, which have been cited more than 500 times. Since leaving Vanderbilt, he has worked at SUNY Upstate Medical University, and now works at Novartis.

According to the ORI, Dzhura was a busy boy at Vanderbilt, faking images and drastically inflating the number of experiments he conducted by duplicating computer files and saving them in nested folders. The total body count from his work includes: Read the rest of this entry »

In August, the Office of Research Integrity announced that it had sanctioned Jun Fu for faking data in a study of the results of a mouse study of NVP-HSP990, a Novartis compound designed to fight brain tumors. Here’s the notice for the study in question, published in Cancer Research:

Former UT-Southwestern cancer researchers faked data in 10 papers: ORI

with 14 comments

ut southwesternThe Office of Research Integrity (ORI) has ruled in a case we’ve been following for nearly two years — and which seems to have been launched after Retraction Watch readers took a careful look at figures from what appeared to be an unrelated case.

Takao Takahashi and Makato Suzuki, both former postdocs at a cancer research center at UT-Southwestern, both “knowingly, intentionally, and recklessly falsified data” in a total of 10 papers, according to the ORI. Takahashi, now at Gifu University in Japan, was responsible for fakery in four papers, while Suzuki, now at Kumamoto University Hospital, also in Japan, falsified data in six.

We reported on the retraction of the four Takahashi papers, and one of the Suzuki papers, in November 2012. At that time, Adi Gazdar, the head of the lab where the researchers worked, told us that

“Research misconduct accounts for a small percentage of total funding”: Study

with 19 comments

elifeHow much money does scientific fraud waste?

That’s an important question, with an answer that may help determine how much attention some people pay to research misconduct. But it’s one that hasn’t been rigorously addressed.

Seeking some clarity,  Andrew Stern, Arturo Casadevall, Grant Steen, and Ferric Fang looked at cases in which the Office of Research Integrity had determined there was misconduct in particular papers. In their study, published today in eLife: Read the rest of this entry »

After leaving there in 2005, he spent three years at the University of Texas Medical Branch in Galveston, and now appears to be a faculty member at Jilin University in China.
