About

Researcher, Engineer & Long-Term Systems Builder

Before focusing on AI systems research, I spent more than fifteen years building production software, leading technical work, and taking products from initial concept through deployment and iteration. I later completed a B.Eng. in Computer Systems Engineering and an MASc focused on compound LLM agents, prompt-only adaptation, and reliable sequential decision-making.

That path shapes how I approach research. I care not only about whether a method works in one demonstration, but also about the infrastructure around it: what information the model receives, how experiments are reproduced, how failures are measured, how cost is accounted for, and how a result can survive contact with a working system.

01

Current research focus

  • Reliable agent systems

    How compound LLM agents should be structured: what they see, how decisions are decomposed, and where deliberation helps or hurts.

  • Evaluation

    Time-to-event methods, failure taxonomies, and cost accounting that reveal when and why agents stop working.

  • Adaptation

    Prompt-only and inference-time methods that let agents improve from experience without weight updates.

  • Interpretability

    Sparse-autoencoder and causal analysis of whether reasoning representations are shared across languages.

Working style

Empirical
Claims are tied to controlled experiments, ablations, and replication across model families.
Hands-on
I write the harness, the connectors, the runner, and the analysis, not only the paper.
Systems-oriented
A method counts when the infrastructure around it (config, logging, retries, reproduction) also works.
Cost-aware
Tokens, calls, and wall-clock are first-class metrics, reported alongside accuracy and return.
Across research and production
Fifteen years of shipping software shape how I scope, build, and hand off research systems.
Direct about uncertainty
Every project page on this site has a limitations section. Workshop papers are labelled as workshop papers.

Contact

Building reliable AI systems requires both research and engineering.

I’m interested in research engineering, applied research, agent infrastructure, evaluation, reliability, interpretability, and research-to-production work.
