Background
Third-year PhD student in the Department of Computer Science at the University of Virginia
Research centered on Reinforcement Learning (RL), spanning both theoretical and practical domains
Theoretical focus: advancing understanding of how RL algorithms learn and adapt in dynamic environments
Practical focus: applying RL to post-training of large language models (LLMs), with emphasis on alignment and reasoning
Also has experience in game theory and mechanism design
