Hello! I am a 1st year CS PhD at Princeton University where I am fortunate to be advised by Prof. Karthik Narasimhan at Princeton Language and Intelligence. I am fascinated by the interactive nature of language, and am actively working on topics including AI alignment, reasoning and agentic behavior especially in multi-agent systems. Previously, I worked as a research scientist in Amazon Foundation Model (Amazon AGI) Post-Training team where I contributed as a founding member to the development of Nova – the state-of-the-art text and multimodal models and Alexa Prize SocialBot with Dr. Yang Liu and Prof. Dilek Hakkani-Tur in Sunnyvale, CA. Before that, I received my Bachelors from Peking University and my Masters from Carnegie Mellon University.
Outside of work, I enjoy badminton, running, reading and exploring local hidden gems. Being a language lover at heart, I’ve been pre-trained with Chinese and fine-tuned on English, Korean, German and Japanese, but I might suffer from catastrophic forgetting sometimes. I enjoy photography and have also touched upon scriptwriting for a bit, and wrote a short film based on a real story during the pandemic time and won several film festival awards.
