Chandra co-authored several key papers in theoretical computer science. Among other contributions, he introduced alternating Turing machines in computational complexity (with Dexter Kozen and Larry Stockmeyer),[4][5] conjunctive queries in databases (with Philip M. Merlin),[6] computable queries (with David Harel),[7] and multiparty communication complexity (with Merrick L. Furst and Richard J. Lipton).[8]

He was a founder of the annual IEEE Symposium on Logic in Computer Science and served as conference chair of the first three conferences, in 1986–8.[9] He was an IEEE Fellow.[10]
