Hi, I am a PhD candidate currently on the job market. I am learning applied algebra at Academy of Mathematics and Systems Science, Chinese Academy of Sciences. Before that, I obtained my bachelor’s degree of mathematics from School of Mathematical Sciences, Zhejiang University in 2021. I am very fortunate to be advised by Prof.Ke Ye of KLMM from Academy of Mathematics and Systems Science. 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 (additive/extremal) combinatorics, (multi-)linear algebra and algebraic complexity theory. For more details, please see my (pre-)publication list.

I am actively seeking a postdoctoral opportunity.

If my research direction aligns with your group’s work or you have any question, I would be delighted to hear from you. I can be reached at chenqiyuan@amss.ac.cn.
