Research Interests

Rachael is continually looking for new collaborations with both academia and industry to work with her in the field of non-destructive evaluation looking at advancing existing techniques, finding new applications and tackling current inspection challenges.

Rachael is a member of the Waikato Robotics, Automation and Sensing (WaiRAS), Centre for Advanced Materials and Manufacture (WaiCAMM) and Resilience, Infrastructure and Sustainable Construction (WaiRISC) Research Groups.

Rachael’s research interests are in the fundamentals of non-destructive evaluation of materials, components and structures. Such inspection applications range from online manufacturing quality control to in-service through life inspections. Research to date has largely focused on the use and development of using imaging techniques such as pulse phase thermography (defect detection), thermoelastic stress analysis (stress distributions) and digital image correlation (displacements/strain) to gather such information. Looking forward it is envisaged that such imaging techniques could be coupled with other sensing systems to reveal complimentary information to build more complete understanding. The overall aim is to build from detecting defects towards assessing the impact of those defects on the component, i.e. there is a defect, now do we care? Work encompasses a variety of traditional and advanced materials, manufacturing and structures.
