I am a Research Fellow in National University of Singapore, where I am a member of NExT++ Lab, supervised by Prof Tat-Seng Chua. With my colleagues, students, and collaborators, we strive to develop trustworthy and Robustness of AI algorithms with better interpretability, generalization, and causality of AI. Our research is motivated by, and contributes to, applications in information retrieval (e.g., collaborative filtering), data mining (e.g., graph pre-training), and causality (e.g., causal inference and causal discovery). My work has several publications in top-tier conferences (e.g., NeurIPS, WWW, KDD, ICML, ICLR, SIGIR) and journals (e.g., TPAMI, TOIS). Moreover, I have served as the PC member for top-tier conferences including NeurIPS, SIGIR, ICLR, KDD, EMNLP, WWW, AAAI, ICML, and WSDM.

Prospective Intern Students

I am looking for highly motivated interns (visiting Ph.D., master, and undergraduate students) to work together on the trustworthiness and robustness of graphs, especially pre-training, interpretability, generalization, and causality, and their applications in real-world scenarios. Please feel free to send me your CV and transcripts, if you have interest. We are also actively looking for opportunities in research, partnership and commercialization in exciting data science projects.
