I am now a researcher at the Center for Complex Geometry at IBS in Daejeon, Korea.
I obtained my Phd degree under the supervision of Laurent Manivel and Thomas Dedieu at Université Toulouse III - Paul Sabatier (now Université de Toulouse). Here is my CV.

My field of research is complex algebraic geometry. More specifically, I am interested in Derived Category, Gromov-Witten Invariants, Quiver Moduli Space, K3 Surfaces, Beauville-Mukai system and Hyper-Kähler Manifolds.

2023-2026: I obtained my Phd degree in mathematics at Université de Toulouse, under the direction of Laurent Manivel and Thomas Dedieu. This thesis studied various aspects of moduli spaces of quiver representations. Here is my Phd thesis pdf.
2021-2023: I did my Master study in mathematics at Université de Toulouse. I finished my Master thesis about Mukai's models of genus 8 and 16 polarized K3 surfaces under the direction of Laurent Manivel. Here is my Master thesis M2.pdf.
2018-2022: I obtained my Bachelor degree in mathematics from ShanDong University.
