About me

I’m Zirui “Ray” Liu, a Ph.D. student from the Department of Computer Science at Rice University, co-advised by Dr. Xia “Ben” Hu and Prof. Vladimir Braverman.

My core research interests lie in large-scale machine learning and machine learning system. I co-design algorithm and system, aiming to scale-up and/or accerlate machine learning models. Some examples include LLM KV Cache quantization, randomized matrix mulplication, and GNN quantization. Besides MLsys, I am also interested in other core problems/applications in LLMs like RAG, long context ability, and LLM safety.

I will join the CS Department at University of Minnesota Twin Cities as an Assistant Professor in Fall 2024

Feel free to reach out if you would like to collaborate on MLSys or on-device ML research.

📧📧 Recruiting 2025 Spring/Fall Ph.D. students and interns: I am looking for self-motivated students with strong background in HPC, NLP, and ML. Feel free to drop me a line to ziruiliu dot recruit at gmail dot com together with resume and transcripts if you are interested.
