About

As an EE student, I am passionate about wireless engineering, communication engineering, computer networking. I have a strong interest in information security, and I'm currently conducting research at UTokyo focused on securing wireless communication. I also enjoy creating things with the help of coding. 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 😎).
