I am a third-year graduate student in computer science at Zhejiang University, advised by Prof. Yunjun Gao.

I have been very fortunate to work with Prof. Zhikun Zhang at Stanford University , with Prof. Christian S. Jensen at Aalborg University , with Prof. Baihua Zheng at Singapore Management University , with Dr. Jianxun Lian and Dr. Xing Xie at Microsoft Research Asia .

My goal is to build reliable models with a focus on their explainability (to facilitate human understanding), data privacy (to preserve users’ privacy), and robustness (to data noise), which guarantee their trustworthiness in critical real-world applications. I have published more than 10 papers at the top international conferences such as VLDB, KDD, SIGIR and ICDE.
