I am a Ph.D. candidate at Yonsei University, currently conducting research at KAIST, where I relocated in February 2024 to continue working with my advisor, Prof. Noseong Park. My research interests span various areas, including graph neural networks, recommender systems, spatio-temporal forecasting, differential equations, and Transformers. I have published multiple papers in prestigious venues including NeurIPS, ICML, ICLR, AAAI, IJCAI, CIKM, WSDM, SIGIR, WSDM, and ICDM. My research has been recognized through the Qualcomm Innovation Fellowship, and I have received Top Reviewer Awards at both NeurIPS 2024, LoG 2024, and KDD 2025. I will be serving as Web Chair for the upcoming CIKM 2025.

I work on developing advanced AI models with a focus on three main areas: (1) Graph Neural Networks & Differential Equations, (2) Recommender Systems & Collaborative Filtering, and (3) Spatiotemporal Forecasting & Applications.
