Ruihang Lai

“It's the start of a new journey.”


I am Ruihang Lai (赖睿航), a first year Ph.D. student at Computer Science Department of Carnegie Mellon University. I’m a member of the CMU Catalyst research group, and am fortunate to be co-advised by Prof. Tianqi Chen and Prof. Todd Mowry.

Prior to joining CMU, I finished my undergraduate at ACM Honors Class, Shanghai Jiao Tong University in June 2022, advised by Prof. Yong Yu.

I was a research intern at OctoML and Catalyst. I am a committer of Apache TVM project.

Aug 29, 2022 Officially becoming a CMU student! I’m excited to continue focusing my research on machine learning compilation!
Jun 22, 2022 Graduated from SJTU today! So excited to see my undergraduate life come to the end 😆 🎓. Can’t wait to join CMU and keep pushing the limits!


My research interests lie in the intersection of computer systems and machine learning, especially the systems for emerging machine learning workloads. It is exciting to build systems that keep up with the trend of machine learning, or even guide the trend of machine learning. Currently my research focuses on dynamism in machine learning compilation, in order to optimize the compilation for machine learning models that involve sparsity, dynamic shapes and dynamic control flow in both inference and training settings.
