I am a third year Ph.D. candidate at School of Information, University of Michigan, Ann Arbor. My advisor is Prof. Qiaozhu Mei. Prior to UMich, I got my Bachelor's degree at Tsinghua University, advised by Prof. Jie Tang.

I'm particularly interested in developing machine learning models for structured-data (i.e., graphs) and multi-task scenarios, which are commonly seen in real-world machine learning problems and applications in industry.
