Dr Amy GandyAmy joined the Department of Materials Science and Engineering in 2011 to investigate the effect of radiation damage on the atomic and nano-structure of model nuclear waste glasses. Her current research focuses on radiation induced damage and recovery mechanisms, and gas bubble formation, in poly-crystalline oxide-based materials and advanced multicomponent alloys for nuclear fission and fusion.

Prior to this, Amy undertook a postdoctoral research position at the University of Manchester (2009-2011), having completed a joint PhD at the University of Salford and the University of Poitiers, France, in 2009 for which she used transmission electron microscopy (TEM) to understand ion beam implantation induced defect formation and interactions during thermal annealing in crystalline and amorphous silicon, relevant to the semiconductor industry.

Career history
  • 2015 - current: Lecturer in Nuclear Engineering, Department of Materials Science and Engineering, University of Sheffield
  • 2011 - 2015: Research Associate, Department of Materials Science and Engineering, University of Sheffield
  • 2009 - 2011: Research Associate, University of Manchester
  • 2006 - 2009: PhD, University of Salford and University of Poitiers, France
  • 1999 - 2003: MPhys Physics and Space Technology, University of Salford

Amy’s research centres on understanding radiation induced defect formation, accumulation, and thermal recovery, and the development of new materials for the next generation of nuclear technologies (fission and fusion). She uses electron microscopy, including ion irradiation and thermal annealing in-situ in a TEM, X-ray diffraction, Raman, FT-IR and X-ray absorption spectroscopies to characterise the structure of materials and ion beam induced defect morphologies.

Amy research is based in the NucleUS Immobilisation Science Laboratory and Functional Materials and Devices groups where she is developing Li-ceramics and advanced multicomponent alloys for nuclear fusion, and investigating helium gas bubble formation and ion beam irradiation induced defect formation and recovery mechanisms in these materials.
