Bio

I am a Research Scientist in the machine learning system group at ByteDance@Seattle. I obtained my PhD degree from Johns Hopkins University in 2022, advised by Prof. Xin Jin. I received my bachelor's degree from Tsinghua University, China. My current focus is on building large-scale training systems for large language models.
