About

Richard J. Colchester is a pioneering researcher at the intersection of biomedical optics, robotics, and minimally invasive surgery. His work centers on developing all-optical ultrasound technologies—where both the generation and detection of ultrasound are achieved using light—and integrating them with robotic systems to enhance surgical precision and safety. Colchester’s major contributions include the design of a robotic multimodal endoscope that combines optical ultrasound imaging with white light stereo cameras, enabling safer navigation during challenging fetoscopic procedures. His research on haptic guidance using all-optical distance sensing has been cited 17 times, and his robotic control of a multimodal rigid endoscope has garnered 11 citations, reflecting the growing impact of his work. Notably, his studies on large-area all-optical ultrasound imaging and robot-assisted optical ultrasound scanning demonstrate his commitment to translating these technologies into clinical tools. By enabling real-time, high-resolution imaging through ultra-miniature instruments, Colchester is helping to reduce risks in fetal surgery and other delicate interventions. His achievements underscore a career dedicated to making minimally invasive procedures safer, smarter, and more accessible.
