Ranjit Kumar Chandra (रंजीत कुमार चंद्रा; born February 2, 1938)[3] is an Indian-born Canadian researcher and self-proclaimed "father of nutritional immunology"[4][5] who committed scientific and health care fraud. Chandra's misconduct was the subject of a 2006 documentary by the Canadian Broadcasting Corporation (CBC). A libel trial in July 2015, concluded that the allegations of fraud against Chandra were truthful; he was ordered to pay $1.6 million to cover CBC's legal fees,[6] and later that year was stripped of his membership in the Order of Canada.[7] As of 2020, four of Chandra's research publications have been retracted, and one has been corrected.[8]
