Hello! I am a second-year Ph.D. student in Computer Science at Cornell University advised by Prof. Alexander Rush. My research interests lie in the broad field of machine learning and natural language processing. Before joining Cornell, I was a research intern at Korea Institute of Science and Technology (KIST). I received a B.A. in Applied Statistics and a B.S.E. in Computer Science and Engineering from Yonsei University.

Current research directions

  • Efficiency: compressing and accelerating large neural language models along multiple axes, including model size, training/inference time, computations, etc.

  • Interpretability: identifying which part of the model or data correlates to language model outputs

  • Robustness: spurious correlations in conditioned text generation

A little bit about myself

My first name "우정" means "friendship" in Korean.

I love cooking, baking, playing tennis, and collecting vinyl records!
