Amy 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.

- Research interests
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). Her group 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's research is based across the NucleUS Immobilisation Science Laboratory (ISL), and Functional Materials and Devices groups where her group are developing Li-ceramics and advanced multicomponent alloys (high entropy alloys) for nuclear fusion, and investigating helium gas bubble formation and ion beam irradiation-induced defect formation and recovery mechanisms in these materials.

We interviewed Amy for the Faculty of Engineering's Wall of Women when she was a Lecturer in Nuclear Engineering. Here's Amy's interview:
The Wall of Women profiles were taken over a 4/5 year time period and are a snapshot of what our engineers were doing at that time.
