I am a first-year Ph.D. student at Carnegie Mellon University, advised by Prof. Chenyan Xiong. My research interests lie in Machine Learning and Natural Language Processing, with a particular focus on data-centric large language models. I am keen on:
- The relationship between data and model performance.
- Tracing the origins of model capabilities (e.g., reasoning) to their data sources.
- Generating higher-quality and more effective training data.
Prior to attending CMU, I earned my bachelor's degree in Software Engineering with the highest honors from Tsinghua University in 2025. During my exchange at the University of Hong Kong, I was fortunate to work with Prof. Tao Yu on computer-use agents.
