林政亨 Jeng-Heng Lin

Jeng-Heng (William) Lin is a PhD student in the OEMI Laboratory at the Department of Biomedical Engineering, National Taiwan University. He currently works on developing dynamic imaging and motion analysis systems for occupational and clinical applications. His ongoing projects include a 2D-vision-based 3D reconstruction framework to estimate L5/S1 joint moments during manual lifting in workers, aiming to provide quantitative tools for assessing spinal loading and preventing work-related musculoskeletal disorders

He received his M.S. degree in Sports Medicine from the Department of Medicine at Kaohsiung Medical University and his B.S. in Physical Education from National Kaohsiung Normal University. During his graduate studies, he developed and integrated an eye-movement feature detection and evaluation system using a Stewart platform (6-DOF motion platform) and low-cost desktop eye trackers to investigate oculomotor function across different neck positions and sampling rates. This work focused on the reliability of smooth pursuit and gaze metrics and explored the feasibility of affordable vestibular and oculomotor assessment systems in clinical practice.

His research interests span biomedical engineering, biomechanics, oculomotor control, motion analysis, traumatic brain injury and concussion, as well as the design of medical devices and assessment systems. He has experience with both marker-based and markerless motion capture, Stewart-platform–based vestibular stimulation, and real-time pupil and gaze tracking, and is involved in system integration, software design, and the development of user-oriented tools for clinicians and industry partners.

William has been actively engaged in translational and entrepreneurial activities. He received the Innovation Excellence Award at the 21st National Innovation Award for an innovative smart device for vestibular system function assessment and has led or co-led multiple teams in national innovation and biodesign competitions, including FITI (From IP to IPO Program), Biodesign Innovation Competition, and Warring States Policy National Innovation and Entrepreneurship Competition. These experiences reflecting his long-term goal of bridging biomechanics, assistive technology, and clinical needs.
