About Us

Integrity. Transparency. Impact

Maximizing our customers' impact with the effective application of state-of-the-art technology

We have extensive experience in many areas including research and education. Our research specialities utilize custom written software for GPU-accelerated volumetric image analysis and data processing. Our education specialities include developing world leading VR medical training simulations with haptic interfaces and novel real-time physics models that enable unprecedented surgical interactivity, and also simpler training applications that use gamification to motivate student engagement and maximize effective learning.

Director's Note

Awards, research papers, conference talks. These are the instruments of exchange of knowledge for academics and researchers. Today's technology exchanges knownledge faster and further than anything in history. After training for over a decade, and specializing for a decade more. the academic model for sharing innovations has limited impact, whereas a successful product launch can see "viral" growth. Faster, leaner, directly to those who can benefit most. Exagen was founded to step away from acadmic measures of success, to test the real-world value of research innovations and engage directly with users.

Whether it’s the natural world, or the tech that empowers us, a deep understanding has always provided deep insights and revealed interesting opportunities and challenges. I’ve specialised in software development for medical research and education applications including innovative surgical training simulations, and new tools that increase speed and remove limitations to amplify biomechanical analyses.

I love to create. I have extensive experience in 3D computer graphics, GPU programming, haptic interaction, and medical image processing, and all aspects of delivering university education and research. I enjoy learning & applying new technologies and creatively pushing the boundaries.

PhD in VR Surgical Simulation. Bachelor of Engineering with Honours (Electrical & Electronic). Senior member of the IEEE. University lecturer of topics such as “Computer Graphics and Interactive Physics”, “Haptic Enabled Systems”, “Computer Programming 2 (C++)”.
