About
Hi šš»! Iām 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 and music language models. My current research focus is on massive text corpora analysis, corpora 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 violinš». 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.
