Position/s

Lecturer/Senior Research Associate - Medical Simulation
School of Computer Science, Engineering and Mathematics

Biography

Simulation will revolutionise medical training in the next decade. Many components of computer games and techniques from other disciplines such as digital effects for movies are readily transferable when developing virtual reality medical simulations. However, key pieces, such as haptic cut-able soft-tissue, are missing from the tool-kit of medical simulation developers. 
Greg's research focuses on the development of new core technology that will enable haptically interactive computer-based simulations of surgical interactions. Since 2002 Greg has prototyped numerous medical simulators that show-case innovations including his PhD research where he developed a new GPU-accelerated approach to sugically interactive soft tissue simulation.

Further information

Since completing the first prototype of ISim for his Engineering Honours Project in 2002, Greg has worked in the simulation industry developing a range of virtual reality simulator prototypes that push the boundaries of what is possible with cutting edge technology. His work includes Defence simulator components, radar image processing algorithms, and numerous applications including ISim version 1 (2002), ISim version 2 (2004), Live Sports Monitoring GPS Tracking (hardware and software - comms, gui, embedded C etc) (2004), Haptic Playground (2004), 3D Skull Jigsaw (2004), CT Data Analysis Wizard (2006), Mobile Phone Psychometric Tester (2006), GPU Tissue Simulation (2007 - 2010), ISim version 3 (2009 with Fabian Lim), and the Flinders Endoscopic Sinus Surgery Simulator (2010).
