Kind of sounds a lot like the German physicist Jan Hendrik Schön. Remember him? The guy who reported having a series of superconducting breakthrough that would change the world, awarded millions of dollars in grants and contracts, given multiple awards, such as Otto-Klung-Weberbank Prize for Physics, and was on the track for a Nobel peace prize...
Until one day, a scientist asked him a question he couldn't answer, and decided to do some research and discovered- Mr. Schön was publishing using the exact same graph for all his discoveries.
