Cosmology!

I am an undergraduate studying astronomy at the University of Science and Technology of China (USTC, Class of 2023) and a member of the Wang Shouguan Talent Program in Astronomy. I am currently an undergraduate intern at the University of Wisconsin–Madison, where my internship runs from July 2026 to January 2027.

My research interests lie in phenomenological cosmology, particularly large-scale structure (LSS), dark energy, and fundamental physics. My current work focuses on:

  • Studying the statistics of halo and galaxy distributions to probe the halo model, under the supervision of Prof. Huiyuan Wang.
  • Exploring neural network methods for constraining non-Gaussianity with cosmic shear, in collaboration with Prof. Moritz Muenchmeyer.

I am also interested in effective field theory (EFT) approaches to large-scale structure and dark energy, which I see as promising tools for understanding the universe.
