My research focus broadly on innovative design and use of machine learning algorithms, especially on large-scale graph data and collective behaviour. Several areas of recent work include:- Popularity in social media – understanding, predicting, and optimization.


I came to ANU in December 2010 after a few memorable years at IBM T J Watson Research Center. Before that I got my degrees at Columbia University in New York City and Tsinghua University in Beijing. My previous webpages are here and here (thanks to wayback machine). When not hacking code/paper or jamming ideas, I can be found peeking through my camera, reading, or playing music badly.
