Graham is a world leading expert in temperature measurement. His work had profoundly changed the way temperature is defined, realised, disseminated and measured. Selected achievements include; playing a leading role in the redefinition of the kelvin, development of new high temperature standards resulting in step change improvements in thermocouple calibration and non-contact high temperature scale realisation, dissemination and comparison, leading research into self-validating and practical primary thermometers (including photonic and quantum-based approaches) and addressing real-world thermometry challenges in diverse fields from aerospace, nuclear decommissioning and medicine.
Graham is the UK representative on the CIPM Consultative Committee for Thermometry (CCT), chairs CCT Working Group (WG) Non-Contact Thermometry and serves on CCT WG Strategy, is past chair of Euramet Technical Committee for Thermometry (2014-2018) and past President of the Institute of Measurement and Control (InstMC) (2018-2019). He is Honorary Professor (Birmingham University, Physics; Glasgow University, Engineering) and visiting Professor (Strathclyde University, Physics).
Awarded the InstMC Callendar Medal for 'innovations in temperature measurement' (2012), conferred D.Sc ‘Improvements in Temperature Measurement’ (Birmingham University, 2015), elected Fellow Royal Academy of Engineering (2019), and received the InstMC Sir Harold Hartley award 'for outstanding contributions to the technology of measurement and control' (2021), elected Honorary Fellow of InstMC and Fellow of the Durham Institute of Research, Development, and Invention (2024).
