About Me
I am a first year CS Ph.D. student in the Computer Science Department @ Rice University, advised by Prof. Hanjie Chen. My research interests lie in Interpretable Machine Learning, with a focus on the interpretability and understanding of language models. Prior to joining Rice, I was a master student at Carnegie Mellon University.
News
💬 Excited to present our work SAFR at NAACL2025 Findings. Superposition is powerful — but it buries interpretability. We control that!
🧠Neurons often mix too many features (superposition) — making models a black box.
🎯 SAFR strategically redistributes neurons:
- 🧩 Monosemantic for important tokens
- 🔗 Polysemantic where interactions matter
