Yuqi Liu
I am currently a postdoc fellow at the University of Leeds. I received my PhD degree from the School of Mathematical Sciences, Fudan University in 2026, and my bachelor degree from the same school in 2021.
My research focuses on:
- Randomized algorithms for eigenvalue problems
- Mixed-precision preconditioning
- Nonlinear eigenvalue problems
- High-performance implementations
