I study how machines learn language — and build systems that make AI more understandable, efficient and accessible.
I build the instruments that make model learning observable, then carry what they reveal into products, policy and teaching. Alongside the research I founded Per Capita Media.

Let's connect
Working on something at the intersection of AI, language, learning, policy or media? Whether you want to collaborate, build, or just compare notes — a message is always welcome.
Research
Understanding how language models learn
Language models are the most powerful learning systems we've built — and we still barely understand how they learn. I build controlled experiments to watch learning unfold: how grammar emerges, how knowledge is represented, and why independently-trained models converge on similar internal structure.
Featured · my instrument
Beetle
Language models as model organisms of human language learning.
Beetle replays learning under controlled conditions. Change one language, one tokenizer, one curriculum — and measure what changes, and what doesn't.
114 bilingual models · 13 first languages · 5 curricula

Build
Smaller, faster AI you can actually own
Most companies don't need a bigger model — they need one they understand, that adapts quickly, runs cheaply, and they actually own. My research turns into practical tools for exactly that.
Model merging
Combining independently-trained models into one — near-term and practical.
Small LM agents
Efficient, deployable agents built on models you can run yourself.
Multilinguality
AI that works beyond the richest few languages.

Ideas & media
AI beyond the lab
AI shouldn't only work for the richest languages, companies or countries. Open, interpretable models make AI something universities, governments and educators can build — not just buy. Research creates ideas; writing tests them; policy puts them to work. That's why I founded Per Capita Media.
Outside research
Research has taken me further than I expected — Seoul, Vancouver, San Diego, Vienna, Morocco. Cambridge still feels like home, but language models have become an unexpected passport.
