Research interests

My research focuses on the control mechanism of a speech articulatory system and speech perception processing. The specific goal of my research is to understand how the somatosensory information arising from orofacial cutaneous mechanoreceptors is utilized in the sensorimotor processing of speech and in speech perception system. I have developed perturbation system associated with facial skin deformation, and have measured articulatory motion while the perturbation system modulates orofacial somatosensation.
