I am a Ph.D. student in the Computer Science and Engineering Department, University of Connecticut. My advisor is Prof. Jinbo Bi. I was supervised by Prof. Fei Wang and had the opportunity to work with Prof. Viktor K. Prasanna, Dr. Jing Huang. Before I came here, I got my M.S. degree at Beijing University of Posts and Telecommunications (BUPT). I have spent some time interning in University of Southern California (2014), Chinese Academic of Science (2015) and JD AI Research (2018).

My primary research interests are in machine learning and deep graph learning using large-scale datasets, with an emphasis on healthcare informatics, knowledge graphs, cheminformatics and bioinformatics.
