Hi, I am a postdoctoral researcher at the Korteweg-de Vries Institute for Mathematics of the University of Amsterdam, mentored by Prof. Jeroen Zuiddam. I obtained my PhD in applied algebra from the Academy of Mathematics and Systems Science, Chinese Academy of Sciences in 2026. During my PhD, I was fortunate to be advised by Prof.Ke Ye of KLMM. Prior to my PhD studies, I obtained my bachelor’s degree of mathematics from School of Mathematical Sciences, Zhejiang University in 2021.

I’m interested in commutative algebra, combinatorics, and their applications. More precisely, I am mainly studying several notions of ranks of tensors and related topics from algebraic complexity theory, (additive/extremal) combinatorics, and (multi/numerical-)linear algebra. For more details, please refer to the list of my (pre-)publication .

I can be reached at q.chen3@uva.nl or chenqiyuan@amss.ac.cn.
