about

I'm a final-year PhD student at the University of Oxford, supervised by Prof. Jakob Foerster, researching how to build autonomous and open-ended AI scientists. I'm currently on an internship at Inherent, after more than a year at Meta Superintelligence Labs on their AI Research Agents team.

Previously: a Computer Science degree from Oxford (second in my cohort), then two startups — Halo, a biotech, and genei.io, Y-Combinator backed and now Coloop.ai.

why ai scientists?

My interest in AI Scientists sprang from my fascination with scientific discovery – how over the last 500 years mankind developed the scientific method and began to make discoveries at an exponentially increasing rate. But I’m equally excited about the next 500 years: I believe solving open science problems is a genuinely good and responsible reason to build powerful AI, as opposed to, say, advertising tools or addictive online videos.

My working model of open-ended scientific discovery is a distributed multi-agent system in which agents:

  • Create tasks they believe will unlock progress toward a goal.
  • Use curricula to prioritise work on promising areas.
  • Tackle tasks to learn and produce insights.
  • Reward insights by the extent to which they unlock or amplify progress elsewhere. This can be a challenging task in itself, often revealing long-delayed, unexpected connections.

Research in this area therefore combines several fields, including LLMs (of course), open endedness, curriculum design, recursive model self-improvement, reinforcement learning and evolutionary search.

  1. AI Research Preference Models2026

    T Foster, B Al Omari, T Fu, T Mann, C Domond, L Cipolina-Kun, B Gauri, et al. · arXiv preprint, 2026

    Research agents can propose far more experiments than they can afford to run. Preference models predict which candidates are worth the GPU time, reaching the unguided agent’s 24-hour performance in roughly 15 hours and setting new state of the art on two AIRS-Bench tasks.

  2. AIRS-Bench: A Suite of Tasks for Frontier AI Research Science Agents2026

    A Lupidi, B Gauri, T Foster, B Al Omari, D Magka, A Pepe, et al. · arXiv preprint, 2026

    Twenty research tasks drawn from state-of-the-art ML papers, spanning language modelling, mathematics, bioinformatics and time series, and assessing the full research lifecycle with no baseline code given. Frontier agents beat human SOTA on four tasks and fall short on the other sixteen.

  3. LILO: Learning to Reason at the Frontier of Learnability2025

    T Foster, A Sims, J Forkel, M Fellows, J Foerster · NeurIPS 2025

    An online curriculum for training LLMs with RL, prioritising high-variance questions and yielding large gains in training efficiency across RL algorithms and reasoning benchmarks.
