• 👋 Hi, I'm Xin Xu, a CSE Ph.D. student at UCSD, advised by Prof. Julian McAuley.
• 👀 I'm interested in efficiently updating and improving LLM behaviors:
  • Trustworthy NLP: LLM mechanistic interpretability, factuality, and toxicity
  • Music Science: music interpretation and controllable music generation
• 🎓 I obtained the CS master's degree from Zhejiang University, advised by Prof. Ningyu Zhang.
• :computer: I was fortunate to intern at Microsoft Research Asia, advised by Xu Tan.
• 🎵 I love music. I was a member of Wenqin Piano Society at Zhejiang University.
