Biography

I am currently pursuring my Ph.D. at Yonsei University, under the mentorship of Prof. Won-Yong Shin within MIDaS. My academic journey began with a Master's degree in Applied Mathematics, which I obtained from Ocean University of China (OUC) in Qingdao, in 2021. My research interests center on graph learning, data analysis, and recommender systems, reflecting my enthusiasm for applying mathematical and computational techniques to understand and solve complex real-world problems.

I have been exploring the integration of diffusion models with graph learning, aiming to tackle real-world problems, such as recommender systems. Recently, my research has focused on cutting-edge techniques, recommender systems, and LLM-based recommender systems, leveraging LLMs to better capture semantic information and enhance recommendation quality.
