Graham's interest in structural geology developed from his initial work in geophysics, and earthquake seismology in particular.   He undertook his PhD at the Bullard Labs in Cambridge, working on the active tectonics of the Algerian Atlas mountains and producing several highly-cited papers.  

In 1984 he moved to Britoil in Glasgow to begin work as an exploration/production geophysicist.   At Britoil he began to investigate fault-block tectonics in the Viking Graben, work which he and Alan Roberts have carried over into their past and present work at Badleys. His seismic interpretations are of sufficient elegance that in 1987 he was asked to demonstrate them to Her Majesty the Queen!.

Graham moved from Britoil to Badleys in early 1988, where he began working on geological and geophysical structural studies.   Early in his career at Badleys he began collaboration on a number of research projects with the Fault Analysis Group at Liverpool University (and subsequently UC Dublin) which have produced several important papers.   Over recent years Graham has developed a particular interest in the mechanisms of fault-seal and their predictability.   This has been developed into our course on Fault Seal Analysis.   Graham was an editor of the Geological Society Special Publication The Geometry of Normal Faults.

Graham is the principal instructor for Badleys long-running Fault Seal Analysis course and has through this medium passed on his expertise to many geoscientists drawn from every continent. He is highly regarded both by his industry and academic colleagues and regularly is invited to present papers at International Conferences.

Graham is a Technical Director of Badley Geoscience Limited.
