I am a second-year CS + AI Phd student at University of Southern California (USC), in the Viterbi School and School of Advanced Computing (SAC), where I am very fortunately advised by Prof. Willie Neiswanger. I obtained my CS Master's and Bachelor's degree at ShanghaiTech University. My research interests include
- 🦙 GenAI, e.g., LLM post-training, reasoning
- 🎰 Decision-making, e.g., RL and Bandits
- 🔬 AI-for-Science, e.g., LLM for biology
