I'm a final year Ph.D. student with the Systems group at the Department of Computer Science of the University of Toronto. My advisor is Prof. Ryan Johnson. I came to Toronto in 2012 fall after receiving my B.Sc. in Computing degree from The Hong Kong Polytechnic University, where I worked with Prof. Zili Shao on embedded systems and non-volatile memory. During my sandwich year, I interned with HSBC's equity derivatives front office in Hong Kong.

I'm interested in exploiting modern hardware (e.g., new memory/storage media, massively parallel processors, ultra-fast network) to build fast and energy-efficient systems, both large (server) and small (embedded).
