Portrait of Greg Ruthenbeck

Greg Ruthenbeck

Entrepreneur, developer and researcher.

About

After sixteen years as an academic and researcher, I am exchanging citations for sales to see whether research papers or products make the bigger impact.

I build software for medical research and education: surgical training simulations, haptic interaction, GPU-accelerated image analysis and simulation tools that remove limits for other researchers. PhD in VR surgical simulation; Bachelor of Engineering with Honours, Electrical and Electronic; senior member of the IEEE.
