Early life and education

Warren received a Ph.D.[1] in artificial intelligence from the University of Edinburgh in 1977 under advisor Robert Kowalski, and (a second advisor) Donald Michie.[2]


Warren worked for the Artificial Intelligence Center at SRI International in the 1980s.[3][4]

He founded the company Quintus Computer Systems in 1983 with William Kornfeld, Lawrence Byrd, Fernando Pereira and Cuthbert Hurd to commercialize the Prolog compiler.[5] Quintus was sold to Intergraph Corporation in 1989.[6]

He has also held an academic position at the University of Bristol Department of Computer Science.[7]
