Portrait of Ziyi Xi

I'm a software engineer on Google's Search Quality team, working on query understanding with applied machine learning. I focus on training and serving small language models with millisecond latency at scale, including fine-tuning, model compression, and hardware–model co-design. Previously, I worked on infrastructure reliability and automated recovery at Google, including TPU systems.

I earned my Ph.D. in Computational Science at Michigan State University, researching AI for science, computational seismology, and high-performance computing. I also hold undergraduate degrees in seismology and computer science from the University of Science and Technology of China.
