Scientist who sued university earns two more retractions, bringing total to five

with 3 comments

A scientist who sued his employer for millions of dollars has earned two more retractions, for papers that had already been flagged by the journal.

By our count, Rakesh Kumar now has five retractions and multiple corrections.

Kumar sued his employer, George Washington University, for $8 million, alleging emotional distress when they put him on leave from his position as department chair following a finding of misconduct. That suit was settled last year, for undisclosed terms.

The two newest retractions in the Journal of Biological Chemistry — which tagged the papers with Expressions of Concern last year — both state that, according to Kumar, the problematic figures were assembled by “specific co-authors” — unnamed — in his lab. Here’s the first notice:

Scientist with three retractions settles lawsuit against George Washington University

A researcher whose work has been subject to three retractions and two expressions of concern has settled a lawsuit he filed against his university for breach of contract and emotional distress.

Rakesh Kumar had sued George Washington University for $8 million, claiming that his employer had relieved him of department chair duties without following the correct procedure, following a finding of misconduct in his lab. He also claimed that the university had either leaked confidential information about an investigation into his work, or at least failed to keep that information from being posted in a comment here on Retraction Watch.

Last year, the university filed a motion to dismiss the case, but in March, a judge allowed some of it to go forward. On Thursday, the parties settled the case.

We asked Kumar’s attorney, Paul Thaler, to describe the terms of the settlement and say whether Kumar would remain employed at George Washington: Read the rest of this entry »

DC court allows part of lawsuit against GW to proceed

with 2 comments

kumarA DC court has denied part of George Washington University’s motion to dismiss a $8 million lawsuit by a biologist who claims his employer mishandled an investigation into his work.

Last spring, GW filed a motion to dismiss the case, brought forward by Rakesh Kumar, who has three retractions.  A judge has allowed the case to proceed, honoring parts of the school’s motion to dismiss, but denying most of it.

The memorandum opinion gives the specifics:

Following an earlier investigation, GW biologist earns two expressions of concern

with 2 comments

3.cover (1)The Journal of Biological Chemistry has flagged two papers by a George Washington University cancer biologist with expressions of concern, following an investigation completed by the university in 2014.

The notes contain little specific information; all we know is that there are questions about the data and conclusions in the papers.

The last author on both papers is Rakesh Kumar, who adds these EoCs to a count that includes, according to our records, three retractions and five corrections. Plus an $8 million lawsuit against his employer for emotional distress when they put him on leave from his position as department chair.

The studies — “Stimulation of inducible nitric oxide by hepatitis B virus transactivator protein HBx requires MTA1 coregulator” and “Regulation of NF-B circuitry by a component of the nucleosome remodeling and deacetylase complex controls inflammatory response homeostasis” — have been cited 22 times and 33 times respectively, according to Thomson Scientific’s Web of Knowledge.

The expression of concern is the same for both papers — and matches others that we’ve seen from JBC:

Third retraction for GWU biologist as university seeks to dismiss his $8 million lawsuit

Cancer biologist Rakesh Kumar has chalked up another retraction, this time for “identical,” “duplicated,” and “replicated” figures and images.

It comes on the heels of a flurry of motions in Kumar’s $8 million lawsuit against his employer, George Washington University, for breach of contract and emotional distress because it removed him as department chair last year and placed his research on hold. Kumar remains employed by the university.

The retracted paper, published in Development in 2004, “Metastasis-associated protein 1 deregulation causes inappropriate mammary gland development and tumorigenesis,” analyzed the role of a protein, MTA1, in mammary gland development and cancer. It was published while Kumar was at M.D. Anderson in Houston, and has been cited 81 times, according to Thomson Scientific’s Web of Knowledge.

By our count, Kumar now has three retractions and five corrections. Numerous anonymous comments on Kumar’s papers have been posted on PubPeer, many of them critiquing images. Here’s the complete notice from Development: Read the rest of this entry »

RW cited in scientist’s $8 million suit against university

Maybe the polar vortex is to blame (chilling effect, and all), but it must be lawsuit season!

First it was Mario Saad, who sued the American Diabetes Association to prevent them from retracting his papers in flagship journal Diabetes. Now Rakesh Kumar is getting in on the action. According to George Washington University student paper the GW Hatchet, Kumar was put on administrative leave from his position as chair of the department of biochemistry and molecular medicine in May 2014, though he was still allowed to run his lab until July 25. In response, he’s suing the university for breach of contract and emotional distress. You can read the whole thing here.

Kumar is asking for $8 million, claiming that GW failed to go through the firing procedure outlined in his tenure contract and owes him because he can’t get a new job.

The exact nature of the accusations against Kumar, who has had five papers corrected and two retracted for problematic images, is unclear. According to the suit, a copy of which RW has obtained: Read the rest of this entry »
