His work centered on the beneficial properties of resveratrol, which is found in red wine,[2] but over twenty of his research papers have been since retracted.
[3][4][5] On January 11, 2012, the University of Connecticut Health Center announced that a review board has found Das guilty of 145 counts of fabrication or falsification of data; the three-year investigation examined more than seven years of activity in Das's lab, and centered on Western blot results that had been manipulated and used in published papers.
[18] Data fabrication by Das was alleged by a university investigation committee to have begun in 2005, when "there was no one in the lab with the expertise to prepare Western blots.
"[13] The investigation report further stated that "given the large number of irregularities discovered, which were done over several years and in several different ways, the review board can only conclude that they were the result of intentional acts of data falsification and fabrication, designed to deceive.
"[19] The university notified 11 scientific journals that published papers authored by Das,[20] and the U.S. Office of Research Integrity launched an independent investigation of his work.
