I'm interested in the Science of Generative Models (e.g., LLMs) where I ask how these models work, when, and why.
I develop holistic, causal, and data-centric approaches to study generative models.
These days, I focus on the data on which such models are trained and draw connections between the data and model behavior.
I'm happy to talk about research in general, and my own work in particular.
If you have any questions about one of my papers, or my overall research, feel free to reach out!
I am on the academic job market!
