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.
