Bio

I am a third year PhD student at the Machine Learning Department, Carnegie Mellon University. I am fortunate to work with my advisor, Prof. Geoff Gordon. Before coming to CMU, I obtained my BEng degree from Department of Computer Science and Technology at Tsinghua University and MMath from the University of Waterloo. My research interests include machine learning and optimization, with particular interests in sequential decision making and inference in probabilistic graphical models.

Misc

I enjoy sketching and calligraphy at my spare time. If I have a long vacation, I also enjoy traveling.
I enjoy online learning (not the Online Learning in machine learning) and discussing with people from all over the world. Take a look of Coursera and Edx if you are also interested.
