Summary
👤
Senior🎓
Top SchoolGuy Davidson is a machine learning researcher with a PhD in cognitive science and AI from NYU CDS, specializing in cognitively-inspired representations of goals and task structure. With 11 years of hands-on experience spanning industry research roles at Meta FAIR and Jane Street and internships at Microsoft and Amazon, he blends theoretical, empirical, and computational approaches to understanding task representations in large language models. His dissertation produced novel mechanistic and computational advances in how goals are represented and generated, and he has extended that work to interpretability studies of LLMs while at Meta. He has practical ML engineering experience—contributing checkpointing and memory-saving features to the well-known Rainbow deep RL repo—so he moves comfortably between code, experiments, and theory. Based in New York, he balances rigorous research with a pragmatic engineering outlook and a curiosity-driven habit of shipping reproducible experimentation infrastructure. Outside work he’s an avid board gamer and hot-sauce hobbyist, hinting at a playful, experimental mindset that informs his research.
