Venkatesan Guruswami is a computer scientist whose research includes coding theory, computational complexity theory, pseudorandomness and the complexity of approximate optimization. A major focus is list decoding of error-correcting codes.^[ref]

Ordinary unique decoding aims to recover one transmitted message; list decoding permits a bounded list of candidate messages when the received word has too many errors for uniqueness. The resulting questions connect the amount of redundancy in a error-correcting code with how much corruption can be handled efficiently. His research profile also describes work on approximate solutions to problems with NP-hardness.^[ref]
