Carsten Lund (b. July 1, 1963) is a theoretical computer scientist working as a researcher at AT&T; Labs. Lund was a co-author on two of five competing papers at the 1990 Symposium on Foundations of Computer Science characterizing complexity classes such as PSPACE and NEXPTIME in terms of interactive proof systems; this work became part of his 1991 Ph.D. thesis from the University of Chicago under the supervision of Lance Fortnow and László Babai, for which he was a runner-up for the 1991 ACM Doctoral Dissertation Award. He is also known for his joint work with Sanjeev Arora, Madhu Sudan, Rajeev Motwani, and Mario Szegedy that discovered the existence of probabilistically checkable proofs for NP-hard problems and used them to prove hardness results for approximation problems; in 2001 he and his co-authors received the Gödel Prize for their share in these discoveries. More recently he has published highly-cited work on internet traffic engineering.
