I am a mathematician and artificial intelligence researcher who specializes in natural language processing, interpretability, and training large language models. Currently I am the Executive Director of EleutherAI, before which I was at Booz Allen Hamilton.

Over the past several years my work has focused on making cutting edge AI technologies more widely accessible through supporting the release of several of the world's most powerful generative models such as GPT-NeoX, BLOOM, VQGAN-CLIP, and OpenFold.

Recently my focus has shifted towards building better understandings of how and why these models work, and what decisions engineers can make to instill desirable behaviors and limit undesirable behaviors in these types of models. I am especially excited about mechanistic interpretability research and work investigating learning dynamics of large language models.
