About

As an EE student, I am deeply interested in wireless engineering and information security. I am currently conducting research at UTokyo where I focus on secure wireless communication at the physical layer level. I am also passionate about software and hardware products, and I often think about what makes a product successful in this day and age. I can speak Cantonese, English, Mandarin Chinese, and Japanese. One of my weirdest hobbies is to fiddle with prettily designed UIs (I often download apps which I don't use just to play with the UIs 😎).
