Hi! I’m Yixin Dong, a Ph.D. student at Carnegie Mellon University, fortunate to be advised by Prof. Tianqi Chen. I hold a Bachelor of Science in Computer Science and Technology from the ACM Honors Class at Shanghai Jiao Tong University.

My research focuses on the intersection of machine learning and systems, with a growing interest in LLM Agents. As a dedicated advocate of open source, I have co-led and contributed to several notable projects, including MLC-LLM and Apache TVM Unity, where I also serve as an Apache TVM Reviewer. I had the privilege of spending a wonderful time at the University of Washington, working with Prof. Luis Ceze.

We have been driving the XGrammar project forward recently. It is a zero-overhead LLM constrained generation engine and has already been adopted by several well-known LLM frameworks.

Feel free to explore my CV to learn more. I’m always open to collaborating with passionate, like-minded individuals.

I am open to advising CMU undergrads and master’s students with backgrounds or interests in LLM post-training (especially RL), CUDA, or (ML) compilers. I’m also happy to chat about research and PhD applications with students from underrepresented groups or anyone in need. Please reach out by email.

Beyond research, I’m a cinephile and a lover of contemporary dance. My favorite movies are Hiroshima mon amour and Il buono, il brutto, il cattivo. If you share similar interests, let’s grab a coffee and chat!
