  • Piezoelectric materials
  • Thin film growth (Pulsed laser deposition)
  • Raman spectroscopy
  • Finite element modelling


  • PhD in Physics, Victoria University of Wellington 2013


Ben’s PhD was awarded for studies undertaken in the Raman Spectroscopy group at Victoria University of Wellington.

From 2013 to 2017 he worked for the extreme ultraviolet lithography research group at the University of Twente, Netherlands, together with scientists from Carl Zeiss and ASML. In both bodies of work, he was investigating the detailed structure and performance of piezoelectric materials.

Now at Callaghan Innovation, Ben uses his in-depth knowledge of these materials to create new products and techniques for New Zealand companies.
