I am currently a graduate student studying mathematics, interested in number theory, algebraic geometry, knot theory, dynamical systems, mathematical biology, and perhaps a little bit combinatorics, due to my best friend.

I am passionate about creating beautiful documents with LaTeX, and have contributed several packages to CTAN: https://ctan.org/author/xu. These codes are not of high quality, but I have been working on improving them. It is my hope that one day I can rewrite all these codes with LaTeX3.
