About Me
Hello! I’m Tianhao Wu, currently a Postdoctoral Researcher at the College of Computing and Data Science, Nanyang Technological University, Singapore, supervised by Prof. Siqiang Luo.
My research lies at the intersection of graph algorithms and mathematical optimization, aiming to make large-scale reasoning and search more interpretable and computationally efficient. I’m particularly interested in graph representation learning and optimal transport.
I obtained my Ph.D. in Mathematics from the Department of Mathematical Sciences, Tsinghua University, in 2025, under the supervision of Prof. Zhongyi Huang and Prof. Hao Wu. Before that, I earned my Bachelor’s degree in Mathematics and Applied Mathematics from the School of Mathematics, Tianjin University, in 2020, where I was advised by Prof. Yong Zhang.
My broader research interests include graph similarity search, graph-based vector databases, and quantization methods.
Outside of research, I enjoy reading, photography, hiking, and writing blogs. Feel free to reach out if you’d like to connect or collaborate!
You can find my CV here: English Version and Chinese Version.
