Materials science for the circular economy

I am a Principal Scientist involved in research and development in the fields of materials science and engineering, with a particular focus on the circular economy. I have worked on diverse projects relating to advanced materials, including the development of novel coatings, functional organic synthesis materials, and composite materials.

In my research I focus on recycling coloured plastics, waste-to-wealth, materials for direct air CO2 capture, and novel manufacturing techniques, such as laser-based additive manufacturing and 3D printing. All these support Callaghan Innovation’s work to advance the New Zealand innovation ecosystem.
