I am an assistant professor in the School of Computing Science at Simon Fraser University (since August 2018). Previously, I was a research engineer at Huawei Canada Research Center in Toronto. I completed my Ph.D. in Computer Science at the University of Toronto in 2017, and received my B.Sc. in Computing degree from Hong Kong Polytechnic University in 2012.

Research Interests

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

My current focus is on data-intensive systems and related areas that impact the design of database systems, such as parallel programming, distributed systems and operating systems. I also have interests in embedded and mobile systems.
