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 algebraic varieties.

  • Hypergeometric motives.

  • Rational homotopy theory.

Publications and preprints

Warning: The papers posted on the arXiv may differ from the published versions! I will solve this problem in the future!

  • 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. Mathematical Research Letters (to appear). [arXiv]

In preparation

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