Hi, I’m Tim.

I am currently exploring how machines learn. I am also interested in solving problems arising from creating and adopting machine intelligence.

Currently, I am working on understanding how transformer language models represent the various entities involved in generating natural language at the Center for Human-Compatible AI.

Previously, I've worked on stress-testing CoT monitoring at LASR Labs and interpretability, red-teaming, and steering of language models with the Algorithmic Alignment Group.
