About Me.

I'm a postdoc fellow at Kavli IPMU in University of Tokyo. I earned my Ph.D. at the University of Pennsylvania in 2023, and my bachelor of Science degree at the University of Science and Technology of China (USTC) in 2018. I'm a passionate theoretical physicist that works mainly on particle cosmology and formal field theory. Besides research, I love literature and handcrafts.
