👋 I am currently pursuing an M.S. in Electrical and Computer Engineering at the University of Illinois Urbana-Champaign, where I started in Fall 2025 and expect to graduate in May 2027. Prior to this, I earned dual bachelor's degrees in Electrical and Computer Engineering from the University of Illinois Urbana-Champaign and Zhejiang University in 2025. I am actively seeking Ph.D. opportunities in machine learning and large language models. Feel free to look at my CV!

I am interested in trustworthy large language models and their applications. My recent work focuses on reasoning, safety, hallucination mitigation, and domain-specific post-training for LLMs.

• LLM safety, attacks, and robustness
• Hallucination detection and mitigation
• Multi-step and compositional reasoning
• Post-training and evaluation for LLMs
• LLM applications for scientific and engineering tasks
