About

Biing-Chwen Chang is a biomedical engineer and roboticist whose research sits at the intersection of assistive technology, human-machine interfaces, and neurological rehabilitation. His work centers on developing innovative robotic and exoskeletal devices to restore functional movement in patients with debilitating conditions such as amyotrophic lateral sclerosis (ALS) and cerebral palsy, with a particular focus on head-neck biomechanics and control. Chang's most significant contributions include pioneering the use of a dynamic robotic neck brace to characterize head motion and muscle electromyography in ALS patients — the first study of its kind — and developing a powered neck exoskeleton enabling head drop patients to regain voluntary head-neck control. His research has also advanced head-neck interfaces as viable joystick alternatives for individuals with limited hand function, demonstrating performance comparable to hand-wrist control in orientation tasks. A standout innovation, his bio-inspired gaze-driven robotic neck brace draws from the vestibulo-ocular reflex to improve head-eye coordination and social interaction for those with neuromuscular impairments. With over 75 cumulative citations across his key publications, Chang's work represents a meaningful step forward in neuroprosthetics and assistive rehabilitation engineering, offering real-world solutions that meaningfully improve patients' quality of life.
