Overview
My research focuses on new technologies for computer-assisted surgery guided by three-dimensional imaging. Current projects include intuitive teleoperation of surgical robots from arbitrary viewpoints, virtual reality, robot-enabled cornea transplantation, and automatic eye imaging. In the long term, I aspire to advance the development of medical technology in robotics and imaging.
