I’m a postdoc working with Yejin Choi at the University of Washington. Previously, I received my PhD from Language Technologies Institute at Carnegie Mellon University, advised by Yulia Tsvetkov. I am a recipient of K&L Gates Presidential Fellowship and KFAS Fellowship, and was selected as UChicago Rising Stars in Data Science. I was a research intern at Meta AI and Adobe Research. For more information, please check my CV.

Research Interests

My research interests are in the area of NLP, AI Ethics, and computational social science. Specifically, my research aims to build adaptable and personalized NLP systems for individuals and groups, with a focus on making technologies both more effective and equitable. Additionally, I develop frameworks to analyze social biases and fairness in AI systems, and work on bridging the gap between CS and CSS to facilitate the adoption of cutting-edge AI models in other disciplines.
