Biography
I am a Postdoctoral Researcher at The Pennsylvania State University (PSU), USA. I received PhD degree in Computer Science at Singapore Management University (SMU), Singapore. My research interests generally lie in Text Mining and Graph Learning. In particular, I have been focusing on Graph Representation Learning, Graph Neural Networks, Large and Multi-modal Language Models, AI for Protein and Health Science, Fact-Checking, with applications in diverse domains, including news, social, e-commerce, science, and healthcare. My first-authored papers are published on top venues, including NeurIPS, ICML, KDD, AAAI, ICDE, CIKM, TKDE, etc.
I am awarded Singapore Data Science Consortium PhD Dissertation Research Fellowship 2021 in recognition of outstanding PhD students across all Singapore universities (only 6 PhD recipients in 2021) and Presidential Doctoral Fellowship at Singapore Management University. I received Best Oral Talk Award Runner-Up on Singapore ACM SIGKDD Symposium 2023. I served as an Instructor and independently taught an undergraduate compulsory course, IS1702 Computational Thinking, for AY2022/23 Term 2 at Singapore Management University. Course materials include data structures, complexity analysis, and algorithm design. Check teaching video recordings here.
