Profile

I’m currently a 1st-year PhD candidate at the University of Tokyo, advised by Prof. Jun Rekimoto. My research interests lie primarily in the topic of voice user interaction, silent speech recognition, and multimodal input technologies. My educational background and work experience span electrical and electronics engineering (B.S., four years at UESTC) and applied computer science (M.S., two years at the University of Tokyo).

My CV is available here (updated Jan 2023)
