Amin Shokrollahi (born 1964) is an Iranian mathematician who has worked on a variety of topics including coding theory and algebraic complexity theory. He is best known for his work on iterative decoding of graph based codes for which he received the IEEE Information Theory Paper Award of 2002 (together with Michael Luby, Michael Mitzenmacher, and Daniel Spielman, as well as Tom Richardson and Ruediger Urbanke). He is one of the inventors of a modern class of practical erasure codes known as tornado codes,and the principal developer of raptor codes,which belong to a class of rateless erasure codes known as Fountain codes. In connection with the work on these codes, he received the IEEE Eric E. Sumner Award in 2007 together with Michael Luby "for bridging mathematics, Internet design and mo
