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.

Qualifications
