I am currently a final year PhD student under the supervision of Prof. Yong Zhang and Prof. Chunxiao Xing at Department of Computer Science and Technology, Tsinghua University. Now, I am also working closely with Prof. Xiangyu Zhao from School of Data Science, City University of Hong Kong. In 2022, I have spent 6 months visiting Nanyang Technological University under the supervision of Prof. Cheng Long. I received my B.S in Software Engineering from Beihang University at 2020. My research interests focus on data imbalance problem in data mining applications, including recommender systems, urban computing and medical healthcare.

During 2024, I have received special offers from Alibaba(T-Star, 阿里星), Kwai(快Star), Tencent(青云计划), Baidu(Aidu), Lixiang(理想+), and etc. I will join Alimama as a Senior Algorithm Engineer from July 2025.
