Ranjit Kumar Chandra, OC (रंजीत कुमार चंद्रा) is a professional in the field of nutrition and immunology who has been accused of committing scientific fraud by the British Medical Journal. His alleged fraud was also the subject of a 2006 documentary by the Canadian Broadcasting Corporation.
In the late 1980s, Chandra was hired by Ross Pharmaceuticals, US manufacturer of Isomil and Similac, to study whether infant formulas could help babies to avoid allergy problems. It was the job of Chandra's nurse, Marilyn Harvey, to find newborns in the St. John's, Newfoundland area whose parents had allergies and who were willing to participate in the research. Nestlé (Good Start) and Mead Johnson had also contacted him for similar studies on their baby formulas. Harvey was the first to raise concerns about Chandra's research data, disputing the accuracy of the number of infants in those studies. Chandra found that the Nestlé and Mead Johnson formulas could protect infants from allergies, but the Ross formula could not, despite nearly identical ingredients in the three studied formulas. In his defense, Chandra later cited study design problems, although he had designed the studies himself. He then claimed that he had not been paid enough money to properly perform the studies.
A study published in the September 2001 edition of Nutrition claimed that his patented multivitamin formula could reverse memory problems in people over the age of 65. However, the same study had been submitted to the British Medical Journal in 2000 and rejected after a review by a statistical expert, who stated that the study had "all the hallmarks of having been completely invented." The BMJ asked Memorial University to investigate. When they, too, found that the study could not possibly have been completed as claimed, they asked Chandra to produce his data. He refused, claiming the university had lost it, and resigned.
As claims from Chandra's studies gained widespread attention from sources such as The New York Times, several other world-renowned scientists began examining his published results and realised they were completely fabricated. By 2005, his vitamin study had been completely debunked and retracted. At one point, Chandra published a study by someone named Amrit Jain in Nutrition Research confirming his previous results. Amrit Jain was supposedly affiliated with the Medical Clinic and Nursing Home, Jaipur, India; however, this entity has never been referred to anywhere except in Amrit Jain's paper. Amrit Jain's mailing address is not in India, but is a rented post office box in Canada. No known attempts to verify Jain's identity or existence have ever been successful.
Although Chandra retired from Memorial University of Newfoundland under a cloud of suspicion, university officials did not charge him with research fraud. At least one university administrator admits that Chandra's allegations of bias and threats of a lawsuit led to the termination of the university's investigation.  Marilyn Harvey would later enter into legal proceedings against Memorial University, claiming that MUN led people to erroneously believe that her allegations against Chandra were unfounded.
It was revealed during Chandra's divorce trial that he has 120 bank accounts spread across about a dozen countries (mostly tax havens), worth over $2 million. He claimed that the funds were held in trust for research; however, many of the accounts were opened as joint accounts and some of them were in the names of other members of his family. The judge in the trial concluded that it was not possible that the money came from his salary as a doctor or as a professor. It is believed the money came from the funds provided to finance the studies he allegedly failed to complete.
