Jingyu Liu (刘经宇)

I am a fourth-year Ph.D. student in the School of Mathematical Sciences at Fudan University, advised by Prof. Yingzhou Li and Prof. Weiguo Gao. I am currently a visiting student at The University of Manchester, hosted by Prof. Stefan Güttel. I received my bachelor’s degree from the School of Mathematical Sciences, Fudan University, in 2022.

Outside of research, I am an enthusiastic runner. My half-marathon PB is 1:41:18, achieved at the Shaoxing Marathon in 2024, and my marathon PB is 4:19:28, achieved at the Nantong Marathon in 2025.
