About

Hui An is a biomedical engineer and rehabilitation researcher whose work sits at the cutting edge of neural engineering, brain-computer interfaces (BCIs), and robotic-assisted mobility. With a career focused on restoring motor function in individuals with spinal cord injury (SCI) and stroke, An has made significant contributions to the development of BCI-controlled assistive technologies that enable ambulation in patients with paraplegia and tetraplegia. His landmark 2013 paper, "Brain-Computer Interface Controlled Robotic Gait Orthosis," has accumulated 187 citations, establishing him as an early pioneer in translating BCI technology into practical rehabilitation tools. This work addressed critical medical co-morbidities associated with wheelchair dependence, including cardiovascular disease and osteoporosis, by enabling voluntary, brain-directed walking. More recently, An has explored bidirectional BCI systems that incorporate sensory feedback alongside motor control, as demonstrated in his 2024 feasibility study on embedded bidirectional BCIs for ambulation. His 2025 investigation into ankle proprioception and post-stroke gait reflects a broadening interest in somatosensory contributions to motor recovery. Collectively, An's research represents a meaningful effort to bridge neuroscience and robotics to improve quality of life for individuals with neurological injuries.
