David majored in physics and applied mathematics at UQ and his first real science job was in environmental modelling for the Queensland Electricity Commission.

David completed a PhD at the University of Sydney on electrochromic switchable window coatings for buildings. He feels that his choice of obscure thesis topic has been vindicated since buying a car with an auto-dimming rear vision mirror and learning that the Boeing 787 Dreamliners have switchable windows instead of shutter blinds.

He worked as an academic in the Applied Physics and Computer Systems departments at the University of Technology, Sydney (UTS) for almost 15 years. His commitment to fostering student learning was recognised in various forums, such as a UTS Teaching Excellence Award in 1997, and a Computer Systems Department Teaching Award in 2003.

David career-changed into research computing support roles and joined The University of Queensland as HPC Manager within ITS in 2007. He has long been using computers to "figure stuff out" and enjoys working with researchers to help them do the same.
