刘禹菡
👋 Hi there!
I am a second-year PhD student at New York University (Courant Institute), supervised by Prof. Eunsol Choi. Previously I worked with Yulia Tsvekov(Prof @UW). I obtained my bachelor’s degree in EE from Xi’an Jiaotong Univerity, advised by Prof. Minnan Luo.
🌋 Research Interests
My research interest lies in developing training and inference methods of machine learning. Recently, I’ve been thinking about:
- how LLM agents adapt to specific user needs with multi-turn interactions and naturally occurring feedback.
- how we break LLM mode collapse and surface diverse yet high-quality generations.
What’s NEW
Aug 2025 🥳First-authored Paper “User Feedback in Human-LLM Dialogues:A Lens to Understand Users But Noisy as a Learning Signal” accepted to EMNLP 2025, Main Conference!
Aug 2024 Begin my CS PhD program at NYU Courant🗽
Dec 2023 Sensetime Scholarship 2023! ✌️ 🎉
Jul 2023 ACL Best Paper Award 🎉for our work “From Pretraining Data to Language Models to Downstream Tasks: Tracking the Trails of Political Biases Leading to Unfair NLP Models”
