George was leader of the atom probe group for over 40 years, where his work included the development of the first three-dimensional atom probe instrument in the world, designed at Oxford in the late 1980s. George is the recipient of many awards for his scientific contributions, including the 2005 Acta Gold Medal, 2006 Institute of Materials Platinum Medal and more recently the 2016 TMS Hume-Rothery award. George retired in 2011 but as Emeritus Professor he still plays an active role in the group working on interests such as atom probe analysis of phase transformations, studies of the role of alloy elements and trace additions on the microstructure, heat treatment and properties of steels and non-ferrous alloys. Atomic scale studies of heterogeneous catalysts.
