Weipeng Xu

I am a PhD candidate in Civil Engineering at the Hong Kong University of Science and Technology (HKUST), where I worked on differentiable physics under the guidance of Prof. Tianju Xue.

I obtained my Bachelor’s degree (2017-2021) in Civil Engineering at the South China University of Technology (SCUT). Then I pursue my Master’s degree (2021-2024) under the supervision of Prof. Peng Wei, during which my research focused on structural topology optimization.

My research interests include computational mechanics, inverse problems, and scientific machine learning. I am particularly interested in developing efficient and elegant algorithms for solving complex engineering problems. You can find my learning notes on my blog.

In my spare time, I enjoy watching videos (history, military, science, etc.), playing games (strategy, card, etc.), and traveling. I am a big fan of Yu-Gi-Oh! since I was a child.

If you are interested in my research or would like to collaborate, please feel free to contact me via email: wxuby@connect.ust.hk.
