Research interest

I like to think about problems in number theory, algebraic geometry, and algebraic topology. Currently, I am working on projects related to the following topics.

• Serre weight conjectures.

• Arithmetic of surfaces.

• Hypergeometric motives.

• Rational homotopy theory.

Publications and preprints

• Irreducibility of geometric Galois representations and the Tate conjecture for a family of elliptic surfaces. (with Lian duan) Mathematical Research Letters (to appear). [arXiv]

• Weight elimination in two dimensions when p=2. Submitted, 2017. [arXiv]

• Integral Sullivan theory. (with Jonathan Scott and Donald Stanley) In preparation.

Invited talks

• Peking Online International Number Theory Seminar, Beijing University. May. 2020 [slide]

• Algebra seminar, University of Pennsylvania. Feb. 2020

• FRAGMENT seminar, Colorado State University. Nov. 2019
