Welcome to my personal site! I am a postdoctoral researcher at the Allen Institute for AI, or AI2 for short, working on the Aristo team. I am also affiliated with Prof. Hanna Hajishirzi’s group at the University of Washington. I received my PhD from Georgia Tech, advised by Prof. Mark Riedl, during which I spent time at Google, Sutter Health, and AI2.
I work on the interpretability and transparency of language models (LMs) and other neural networks, with the goal of increasing their reliability, safety, and performance. I also focus on providing natural language explanations for users of LMs.
I am on the academic job market for the 2024-2025 cycle! Please reach out if you believe I would be a good fit.
