Photovoltaic and Renewable Energy Engineering

I am a Research and Teaching academic in the School of Photovoltaic and Renewable Energy Engineering and an ARC Future Fellow (2017-2021).  My research focuses on the areas of silicon solar cell metallisation and interconnection, optical modelling for photovoltaics and more recently high power lithium ion storage and autonomous solar energy harvesting devices.  Within the Learning & Teaching space, I  have been activley involved in developing innovative teaching approaches, especially using gamification for greater student engagement. I have led the development of both the PV Factory and PlayEnergy teaching software and will in 2020 lead one of the initial vertically-integrated projects in the Faculty of Engineering's project-based learning trial. Prior to my employment at UNSW in 2010, I worked as a research scientist at Canon Information Systems Research Australia, where I was involved in research ranging from display and printing device simulations to the development of materials/technology for printing, imaging and display applications.
