About

Un-Je Yang is a leading figure in surgical and rehabilitation robotics, specializing in novel mechanisms that bridge the gap between human dexterity and robotic precision. Her most impactful work centers on single-port surgical robots, where she engineered a novel elbow joint mechanism for high force transmission—a critical solution to the collision and triangulation challenges inherent in single-incision laparoscopic surgery. This paper, her most cited with 27 citations, demonstrates her ability to solve real-world clinical bottlenecks. Yang has also made significant contributions to microsurgery, developing a robot mechanism with mechanical motion scalability that seamlessly transitions between precise intraocular movements and larger reconstructive motions. Beyond surgery, she has advanced rehabilitation robotics, designing a frozen shoulder rehabilitation robot that uses motion capture data to guide therapy, with a unique ball-joint mechanism for bilateral shoulder treatment. Her work is characterized by a deep understanding of mechanical design and clinical need, resulting in systems that are both innovative and practical. With a growing citation impact, Yang’s research is shaping the future of robot-assisted medicine, offering safer, more effective tools for surgeons and therapists alike.
