About

Hi 👋🏻! I’m an undergraduate student at the University of Washington (UW), majoring in computer science with a minor in music. At UW, I am fortunate to work with Professor Hannaneh Hajishirzi and Professor Noah A. Smith, and I am mentored by Jiacheng Liu and Alisa Liu.

My research interest lies in natural language processing with a focus on large language models. My current research focuses on massive text corpora analysis, data curation for LLM pretraining, and tokenization.

I am actively seeking PhD positions for fall 2026. Please feel free to reach out!

Beyond research, I am a classical musician playing the violin🎻. I study with Professor Ronald Patterson and Professor Xiongda Jiang. I served as first violinist of UW Symphony Orchestra and associate concertmaster of Beijing Sun Youth Orchestra. I have performed as soloist at the National Centre for the Performing Arts and the Forbidden City Concert Hall, and as tutti at Benaroya Hall and Meany Center.
