Emeritus Professor



Peter Gray is well known in the International Database Research community. After a physics PhD at Oxford, and working on Production Control Systems with Plessey, he has been at Aberdeen University since 1968 and was awarded a personal chair in 1989. He started there with a pioneering group (1968-72) on both Equational and Logic Programming and then applied this to the integration of heterogeneous data models, developing the P/FDM testbed using Prolog. He has contributed articles to Springer’s on-line Encyclopedia of Database Systems (2010). From 1996-2000 he headed the EPSRC-funded KRAFT consortium which built an evolving network for knowledge fusion using CLP and mediators.
