I am currently a PhD candidate (planning to graduate in August 2017) in the Department of Computer Science, the University of Pittsburgh. I come from Hong Kong. I speak Cantonese, English, and Mandarin. My Chinese name is 容 嘉 偉 (YUNG Ka Wai), but I have been using the English name- Duncan, for many years.

If you ask me why I do a PhD, I would say it's because of curiosity. Everything builds on top of it.
