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.

External Responsibilities

For many years I have been Secretary of Branch Committee of the local Aberdeen branch of the British Computer Society (


I am a (Lay) Reader in the Church of Scotland (licensed in 1979). This means I am licensed to preach and conduct services, but not to conduct sacraments.  I have preached in Kings College Chapel.

I am a member (since about 2000) of the Aberdeenshire Theological Circle, which meets monthly in the Chaplaincy Centre to hear and discuss papers presented by members.

I have written a commentary (for non-specialists or searchers) on the Apostles Creed - a foundation declaration of faith going back to Roman times.  Follow this Link  and click on a line of the creed to see an interpretation.

I was strongly influenced in this by Prof J.S. McEwen's commentary "Why We Are Christians" (1970) which is now alas out of print.

Supervision of Theses at Aberdeen 1976 to 2008
