Professor Kuball has revolutionised the field of thermal management of electronics since joining the University of Bristol in 1997, after working in the USA and Germany. With power densities in semiconductor devices reaching levels approaching the surface of the sun, managing device temperature has become a prime challenge in ensuring device reliability in many electronic devices. One major issue has been temperature measurement at sub-micron spatial and nanosecond time resolution, which Professor Kuball’s work has essentially solved by developing Raman thermography. The IEEE Grade of Fellow is conferred by the IEEE Board of Directors upon a person with an outstanding record of accomplishments in any of the IEEE fields of interest. The total number selected in any one year cannot exceed one-tenth of one- percent of the total voting membership. IEEE Fellow is the highest grade of membership and is recognised by the technical community as a prestigious honour and an important career achievement.
