Jonathan Hyde


Jonathan Hyde joined the nuclear industry in 1995 after completing a postdoctoral fellowship at the University of Oxford and working as a visiting research scientist at Oak Ridge National Laboratory. He has since worked for UKAEA, AEA Technology and the National Nuclear Laboratory, taking on a number of roles including R&D and management. He is currently both Chief Technology Officer for the Reactor and Operations Support business and a Senior Fellow in Nuclear Materials.  In addition, he collaborates with academia and contributes to the work of several technical working groups and advisory boards. He has co-authored ~90 publications and is a Charted Engineer and Fellow of the IOMMM.

Key Areas of Expertise

Jonathan is an expert on characterising the microstructure of materials and developing mechanistic understanding of radiation damage.

Key Achievements

Jonathan’s achievements include:

  • Developing many of the statistical techniques now routinely used worldwide to analyse data from Atom Probe Tomography
  • Promoting the use of a combination of microstructural techniques to underpin mechanistic understanding of the degradation of materials which led to several international research programmes
  • Introducing an annual award within NNL – the Lawrence Medal – for the Best External Scientific/Technical (BEST) Publication
  • NNL “Inspiring Leader”, 2017
