I earned my B.S., M.S., and Ph.D. degrees in Mechanical Engineering from Sogang University, Seoul, South Korea, in 2016, 2018, and 2022, respectively. My academic journey focused on hardware development and control algorithms for gait rehabilitation robots. Our research team achieved medical device certification from the Korea Food and Drug Administration (KFDA), enabling the deployment of rehabilitation robots in six hospitals across Korea. Over three years, we collected medical robotic data from stroke patients and physical therapists, using machine learning and control algorithms to develop and implement an AI-driven therapist for gait rehabilitation.
Core expertise includes Control System Design, Machine Learning, Human-Robot Interaction, Mechanical Design using NX and Solidworks, and developing software in Python, C/C++, Matlab/Simulink, LabVIEW, and ROS.
