My name is Haoyu Zhang (张皓宇). I am currently pursuing a Ph.D. in the Department of Computer Science at the College of Computing, City University of Hong Kong (September 2025 - present). I completed my undergraduate studies in Financial Mathematics at Zhongnan University of Economics and Law (September 2021 - June 2025). My research interests include spatiotemporal data mining, graph neural networks, AI for science, and large language models.
