## Bio

Interpretability researcher. He co-authored *Zoom In*, *Curve Detectors* (Distill, 2020) and *Multimodal Neurons* (Distill, 2021) with
Chris Olah and others. At OpenAI he started the 2023 automated interpretability project, *Language models can explain neurons in language
models* (Bills, Cammarata, Mossing et al.). In October 2026, at Goodfire, he published the essay "Neural Networks Are Already Clean"
(see 2026-10-15-cammarata-goodfire-neural-networks-already-clean).
