Asle Sudbø (born 3 May 1961) is a Professor of Physics at the Norwegian University of Science and Technology (NTNU). He was a co-author (with his twin brother, Jon Sudbø, and his brother's wife, ) of two articles in The Lancet and The New England Journal of Medicine that were since found be based on scientific fraud and subsequently retracted in 2006. The editor of The Lancet described this as the biggest scientific fraud conducted by a single researcher ever. However, his brother finally accepted all responsibilities and claimed only he was responsible for the fraud. An official inquiry into Asle Sudbø's involvement with his brother's fabrication took place. The official commission concluded that Jon Sudbø alone was responsible, and allegations against Asle Sudbø was proven to be wrong.
