About
Kyung Koh is a researcher whose work sits at the intersection of robotics, biomechanics, and rehabilitation engineering. Their primary research areas include the control of series elastic actuators (SEAs), human-robot interaction, and the analysis of motor impairment following stroke. Koh’s most significant contribution is the development of a robust impedance controller for SEAs using singular perturbation theory, a 2019 paper that has garnered 41 citations. This work is pivotal for enhancing safety and compliance in human-robot interaction by allowing flexible adjustment of driving-point impedance, a critical feature for assistive and collaborative robots. Additionally, Koh has advanced the field of electromyography (EMG)-based control, demonstrating simultaneous estimation of joint angle and torque during hand interactions—a technique vital for intuitive prosthetic and exoskeleton control. Their research also extends to clinical applications, investigating abnormal upper extremity coordination in stroke survivors during target reaching, with findings that inform better identification of motor impairment and rehabilitation strategies. Through these contributions, Koh is shaping safer, more adaptive robotic systems and deepening our understanding of human motor control in both healthy and pathological states.
