About me

I am a Postdoctoral member at Morningside Center of Mathematics, Academy of Mathematics and Systems Science. My postdoc mentor is Baohua Fu. I am interested in algebraic geometry, in particular on algberaic cycles, Hodge theory, cubic hypersurfaces and hyper-Kähler varieties.

My curriculum vitae is here.
