About Me

I am a third-year CS PhD student at Penn State University advised by Dr. Rui Zhang. My research interests lie in natural language processing, specifically in making better use of available and unavailable data to develop better model. I am particularly want to explore the following questions:

• With millions of data, millions of annotators, is it exhaustive enough to train a strong specialized model?
• What strategies can be employed to unify diverse labeled datasets for training universal models across multiple tasks?
• When combining heterogeneous datasets, how can we maintain and verify data quality and consistency?

I’m also interested in the applications of LLMs in Computer Science Education (CSEdu).
