My main research interests are biological signal processing, such as Electroencephalogram (EEG) and Elecromyography (EMG). The purpose of processing these signals is to extract the movement intentions of human, and use these intentions to interact with external environment, such as computers, robotic devices, or even other humans. Currently, the emphasis of my research is on using the above signal analysis and processing tools for applications in neurorehabilitation engineering, through intelligent human-machine interfaces (HMI), including brain-computer interface (BCI), and muscle-man-interface (MMI). Specific applications that I am working on include upper limb prosthetic control (for amputees) and rehabilitation of motor functions for patients suffered stroke. I am also interested in the broader application areas as more general human machine interfaces in fields such as neural plasticity (cortical and peripheral), ergonomics, intelligent manufacturing systems and other related topics.
