About
Hoon Jai Chun is a pioneering gastroenterologist and endoscopic surgeon whose research sits at the cutting edge of robotic-assisted endoscopy and minimally invasive gastrointestinal procedures. He has dedicated much of his career to advancing endoscopic submucosal dissection (ESD), a technically demanding technique used to remove early-stage gastrointestinal tumors, with a particular focus on integrating robotic technology to enhance its safety, precision, and accessibility. Chun's most influential contributions center on the development and clinical validation of robotic assistive devices for ESD across gastric and colorectal applications. His landmark pilot study on a robotic assistive arm in porcine models (2019, 24 citations) laid the groundwork for a series of progressively sophisticated innovations, culminating in first-in-human clinical trials by 2025. His work on retractable robotic traction devices and dual-function robotic grippers addresses two longstanding challenges in ESD — tissue visibility and defect closure — demonstrating both engineering creativity and clinical pragmatism. An early interest in 3D endoscopic imaging (2012) signals the breadth of his vision, recognizing the potential of spatial visualization in endoscopy long before it became mainstream. With a growing citation record and multiple device innovations reaching human trials, Chun represents a formative voice in the roboticization of therapeutic endoscopy.
