Hello! ☕

I’m Repo, a graduate student in Nuclear Energy Science and Technology at the University of Chinese Academy of Sciences (UCAS).

This blog records my learning journey, research, and the technical problems I encounter along the way. Its main subjects include nuclear science, materials science, computational methods, LaTeX, Git, and personal website development. I also write about graduate life, self-management, and the ideas that help me grow.

I hope this site becomes more than a knowledge repository: a durable record of how my work and thinking develop over time. If something here helps you, I will be delighted.

Suggestions, discussion, and criticism are always welcome. You can reach me at repoexr@163.com.
