My research and teaching interest is Computer-Assisted Surgery and Interventions. This is a fascinating and complex field that covers medical imaging, image computing, scientific visualization, surgical planning and navigation, robotics, biosensors and, perhaps most importantly, integration of all these into workable clinical systems and translating them to clinical use. I further specialize in minimally invasive percutaneous (through the skin) interventions performed under image guidance, with primary application in the detection and treatment of cancer. For details, please visit my Laboratory for Percutaneous Surgery, or as we call it affectionately: the Perk Lab, online.
