I am a postdoc in the Department of Computer Science, Harvard University from July 2020, where I will work with Professor Milind Tambe and Professor Hima Lakkaraju . Previously I did my first postdoc in the Department of Computer Science, Dartmouth College from July 2018, working with Professor V.S. Subrahmanian. I obtained my PhD from Interdisciplinary Graduate School (IGS), Nanyang Technological University (NTU) in 2018, where I was advised by Professor Bo An. I got my B.S. in Physics from University of Science and Technology of China (USTC) in 2013.
I study AI techniques that help understand the world and benefit the society. In particular, I am interested in reinforcement learning, graph/network-structured learning models, deep generative models, and predictive decision making. I am also interested in social aspects of AI systems such as interpretability, fairness and safety. I work on graph data, textual data, time-series data, and multi-modal data), in domains such as cybersecurity, online social networks, public health and transportation. Here are some examples of my research projects.
