Bio

Hi! I'm a second-year PhD student in Computer Science and Engineering at Santa Clara University, working under the guidance of Professor Yi Fang. Prior to joining SCU, I completed my undergraduate degree in Physics at the University of California, Davis. I'm currently on track to graduate in 2028.

Research

My research focus is on the potential and challenges of leveraging LLMs for Information Retrieval, particularly in reasoning-based LLM reranking, retrieval augmented generation (RAG), and synthetic training data generation for IR systems.

News 🎉🎉

• Our paper "ELOQ: Resources for Enhancing LLM Detection of Out-of-Scope Questions" was recently accepted to SIGIR 2025 Resource & Reproducibility Track.
• I will be joining Amazon as a Data Scientist Intern in summer 2025.
