Kaye Morgan

Short CV

In 2011, Kaye Morgan graduated with her PhD from the School of Physics at Monash University in Australia. Completed under the supervision of David Paganin and Karen Siu, she worked on modeling and capturing phase contrast x-ray images at a synchrotron source. Kaye Morgan then began a three-year research fellowship at Monash, funded by a Discovery Early Career Researcher Award from the Australian Research Council. This project focused on developing and applying a new method of phase contrast x-ray imaging that tracks sample-induced distortions of a projected reference pattern. This method achieves both sufficient sensitivity to differentiate soft tissues and the speed necessary to capture biological dynamics at high resolution. Using this method and others, Kaye Morgan collaborated with biomedical researchers to non-invasively capture airway surface dynamics to inform airway treatment development. She is now a Veski Victorian Post-graduate Research Fellow at Monash University, a fellowship which incorporates two years visiting Technische Universität München, supported by her Hans Fischer fellowship and hosted by Prof Franz Pfeiffer.

Research Interests

Dr. Morgan works in the field of phase contrast x-ray imaging (PCXI), developing and applying new methods for non-invasively imaging soft tissue at high resolution. PCXI reveals soft tissue structures like the lungs and airways in exquisite detail, and new-generation x-ray sources enable the capture of not only structural information, but also high-speed dynamics in an 'x-ray movie'.

Areas of research include: 

  • Applying PCXI to answer research questions, largely in biomedicine.
    For example, imaging the airway surface to assess the ability of a new Cystic Fibrosis treatment to produce sufficient airway hydration for rapid clearance of inhaled debris.
  • Translating PCXI from a synchrotron x-ray source to a compact x-ray source for better research accessibility and clinical availability.
  • Developing PCXI methods to meet the aims mentioned above, to extract additional information about the sample, and to minimise the associated radiation dose. To date, this development has been centred on the single-grid/paper-analyser/speckle-tracking techniques.
  • Modelling PCXI in computer simulations for experimental planning and set-up optimisation.
