Reasoning with Machines Lab

@ University of Oxford

Led by Prof. Adam Mahdi, the lab advances the science of AI evaluation, benchmarking, safety and security. Through rigorous empirical research we study how LLMs and agentic systems reason, interact with humans and drive scientific discovery — alongside industry partners deploying AI where reliability matters.

Research Themes

Research Themes

We treat language models the way a public laboratory treats any new instrument: measure first, theorise second, publish the full method so others can check the work.

  • Open methods
  • Open code & data
  • Open critique
  1. § 1.1
    Evaluation

    Benchmarks and Evaluation

    We develop the science of LLM evaluation, setting the standard for rigorous assessment and identifying hidden risks before they matter.

    RecentStrategic Navigation or Stochastic Search? How Agents and Humans Reason Over Document Collections
  2. § 1.2
    Safety

    AI Safety and Security

    From bias and toxicity to agentic misalignment, we study the full spectrum of AI risk and develop the technical and governance tools to address it.

    RecentA Positive Case for Faithfulness: LLM Self-Explanations Help Predict Model Behavior
  3. § 1.3
    Agentic

    Agentic AI for Science

    We build agentic systems that automate scientific knowledge synthesis and discovery, with a focus on agents that are reliable, transparent and domain-grounded.

    RecentStrategic Navigation or Stochastic Search? How Agents and Humans Reason Over Document Collections
  4. § 1.4
    Human-AI

    Human–AI Interaction

    We run large-scale empirical studies on how people use AI for high stakes decisions, from healthcare and law to policy and beyond.

The same systems now answering medical questions, drafting policy, and mediating public information should be measured with the same care as any other tool that affects public life.

How to work with the lab
Open to partners worldwide

We collaborate with people who care about getting AI right.

Three ways in. Each begins with a conversation, and each ends with published outputs the public can read. We do not run NDAs over findings; we work on questions that benefit from being in the open.

  1. Workshops for industry teams

    On-site sessions for product and ML teams on evaluation, safety, and agent reliability.

    Half-day to multi-week formats. For teams shipping LLM products in healthcare, finance, retail, and government.

    Book a workshop
  2. Tools co-built with engineering partners

    We work with engineering partners to turn lab work into tools other teams can run.

    Evaluation harnesses, safety dashboards, agentic-research platforms. We build them with partners we trust, carrying the research methods through to the code.

    See our builds
  3. Research partnerships

    Applied research collaborations with foundations, governments, and large companies.

    Multi-year programmes: shared roadmaps, sponsored DPhil studentships, named labs.
