I completed my Ph.D at Queen's University in 2012. My research has been focused on exploring the link between speech perception and production. The two sides of spoken language are linked somehow is not in dispute, the neural mechanisms subserving the link, however, remain unclear. An indepth understanding of the coupling between the auditory perception and articulation is crucial to the study of human communication, and instrumental to the investigation of sensory-motor integration in general. I have been using functional magnetic resonance imaging (fMRI) at Centre for Neuroscience Studies to examine the brain regions in which activity during speech production is modulated based on an array of manipulated auditory feedback, which are presumably the regions that are implicated in the online vocal motor control. In addition, I am working on a behavioral study that investigates how sensitive we are to the vocalizations of ourselves and others.
I hold an M.Sc. (Master of Science) in Neuroscience from Queen's University, an M.A.Sc (Master of Applied Science) in Software Engineering and Mathematical Optimization from McMaster University, Ontario, Canada, and a B.E. (Bachelor of Engineering) in Electrical Engineering from Wuhan University, Wuhan, China.
