Jingyu Liu (刘经宇)

I’m a fourth year Ph.D. student in the School of Mathematical Sciences, Fudan University. My advisors are Prof. Yingzhou Li and Prof. Weiguo Gao. Currently, I am a visiting student at The University of Manchester, hosted by Prof. Stefan Güttel. I obtained my bachelor degree in 2022, from the School of Mathematical Sciences, Fudan University.

I’m also an enthusiast of running. My half marathon PB is 1:41:18 at the Shaoxing Marathon in 2024 and my marathon PB is 4:19:28 at the Nantong Marathon in 2025.
