Cryogenic refrigeration innovator

I work in the Advanced Engineering and Materials team as a Principal Research Engineer specialising in fluids and thermodynamics. My expertise lies in computer-aided engineering, fluid-related machinery and manufacturing.

I began my career as an R&D engineer at Hamilton Jet and later as a plastic injection mould designer and NC programmer for the motor trade industry. Working in industrial design enhanced my consultancy skills and led to working with many New Zealand manufacturers. I joined Industrial Research Ltd (IRL) where I led a significant research program in cryogenic refrigeration involving the development and commercialisation of a novel refrigerator technology.

Since the successful transfer of cryogenic refrigeration technology to industry (Fabrum), I have been providing CFD and computational engineering services as part of Callaghan Innovation's Engineering team. Bob Buckley is an inspiring leader who played a significant role in my professional development. He led the superconductivity team at IRL that is now the Robinson Research institute. 

I am a member of the Cryogenic Society of America and have published in the fields of cryogenics, materials and superconductivity. Additionally, I have been associated with Callaghan Innovation projects such as Cool Runnings, Ocean Max and Cold Roads Ahead.
