I am an applied scientist at Amazon Web Services (AWS), working with Dr. Yanjun Qi on trustworthy LLMs. I obtained my Ph.D. in Computer Science at University of Virginia in 2024, advised by Prof. Yangfeng Ji.

My research focuses on developing controllable human-AI collaborative text generation systems, which comprise three components:

  • User Intention Modeling: modeling user requirements with user intention taxonomy to control and evaluate LLMs (ACL2022, EMNLP2022).
  • Controllable LLMs Development: controlling the generation of LLMs through fine-tuning parameter-efficient modules (EMNLP2021), modeling variational context variables (ACL-WS2022), self-training (EMNLP2022) and reinforcement learning (EMNLP2019, 2023).
  • Human-AI Interaction Application: developing human-AI collaborative writing systems (ACL-WS2022).
