Hi, I’m currently a PhD student at The Hong Kong Polytechnic University (PolyU) under the Department of Data Science and Artificial Intelligence. I’m honored to study under the supervison of Prof. Huang Jian. Prior to that, I served as research assistant under the supervison of Prof. Wang Chao at Southern University of Science and Technology (SUSTech) and achieved my Bachelor degree in Statistics at SUSTech under the supervision of Prof. Shao Qiman.

My research interests lie in Statistical Learning, Semi-supervised learning and Self-Supervised Learning. I am currently primarily focused on the Open-set Semi-Supervised Learning problem, as well as the quality-quantity trade-off issue in pseudo-label based algorithms. More broadly, the primary objective of my research is to apply statistical theorey to address the practical problems rising in machine learning.
