Biography

I am a fifth year Ph.D. student in Computer Science at Georgia Institute of Technology. I work with Prof. Le Song and Prof. Hongyuan Zha. I received B.S. in Mathematics in the Mathematics Elite Program from Xi'an Jiaotong University in 2013, under the supervision of Prof. Zongben Xu.

I interned at Microsoft Research working with Vasilis Syrgkanis and Matt Taddy on the Alice project on Economic AI. I designed models and learning algorithms to analyze the bidding behavior of advertisers in sponsored search auctions. I also interned at IBM Research working with Aditya Pal and Michelle Zhou. I designed algorithms to analyze users’ emotions, which have been used in the IBM Watson Personal Analytics Platform.

I am the recipient of the IBM PhD Fellowship 2017-2018.

Research Interests

My research focuses on machine learning models and scalable algorithms for statistical analysis of users’ temporal and strategic behaviors over networks. Specifically, I work in the area of temporal point processes, stochastic differential equations, online learning, inverse reinforcement learning and stochastic optimal control. Important applications of my work include analyzing users’ event patterns, understanding users’ utility functions, recommending the correct items to users at a proper time, and designing policies to promote users’ engagement in social media and social networks.
