I am a Research Scientist in Nanyang Technological University (NTU) worked with Prof. Han Yu. I am also appointed as an Honorary Postdoctoral Research Fellow at Chinese University of Hong Kong where I received my Ph.D. degree advised by Prof. Irwin King.
My research interest is broadly Representation Learning, focusing on extracting meaningful representation from various data types, including unlabeled, noisy, adversarial, and graph data. Specifically, I recently focus on theoretical and algorithmic approaches for Large Language Models (Self-Supervised Learning, Parameter Efficient Fintuining), Safety of Foundation Models (Federated, Watermarking), and Graph Learning.
Prior to my Ph.D., I have also worked as Senior Applied Machine Learning Engineer at Alibaba Group and JD.com.
