Chandra (30 July 1948 – 15 November 2014[2]) was a computer scientist at Microsoft Research in Mountain View, California, United States, where he was a general manager at the Internet Services Research Center.[3] Chandra received his PhD in Computer Science from Stanford University, an MS from University of California, Berkeley, and a BTech from IIT Kanpur. He was previously Director of Database and Distributed Systems at IBM Almaden Research Center. 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] References1. ^{{MathGenealogy|id=111506}} 2. ^{{cite web | url=http://www.skylawnmemorialpark.com/obituaries/Ashok-Chandra/ | title=Dr. Ashok Kumar Chandra Obituary | accessdate=29 May 2015}} 3. ^{{cite web|title=Ashok K.
