My name is Peiyuan Liao and I’m currently an undergraduate student at Carnegie Mellon University School of Computer Science. I am interested in theoretical and applied topics in the intersection between machine learning, systems engineering, and programming language theory.

I’m also involved in several online computer-science communities, such as Kaggle (link in tab) and Codewars (real-time ranking below).

Currently I’m working on an interactive webpage for my research interests and knowledge map, so stay tuned for updates :)


Besides my academic interests, I enjoy taking pictures, learning foreign languages and playing squash.
