I run Base Labs, a research lab by Baseten that works to advance and democratise open-source intelligence. I got to Baseten by cofounding Parsed to build specialised open-source models that beat the frontier labs. We raised a seed round and were acquired by Baseten at the end of 2025, where we continued to post-train specialised models for one company at a time. Base Labs takes the same bet but at 1:n scale instead of 1:1; that is open environments, data, recipes and models that anyone can build on.

Before all this I was briefly a DPhil student in machine learning at Oxford under Jakob Foerster, a General Sir John Monash Scholar, and a Tuckwell Scholar at ANU, and I cofounded Rake News for personalised, debiased news with language models. I like basketball, writing, and reading anything my mum recommends.
