About Me

How language controls systems — biological and artificial.

About Me

I'm from the kind of place in Western Australia where the sky is bigger than the town. Red dirt, mine sites, not much else. Somewhere between there and a PhD in cognitive neuroscience I got fixated on a single question: how does a brain hear a sentence and know what to do?

I spent years in the scanner room mapping that process — watching prefrontal cortex light up as people turned instructions into action. Then I left academia and discovered the same problem wearing different clothes: language models parsing prompts, agents executing tool calls, systems where a misplaced word isn't just confusing — it's a vulnerability.

Now I build and break these systems for a living. I've led AI teams in insurance and mining, published on prompt injection and reasoning model safety, and run a small consultancy for companies that want to deploy AI without ending up in the newspaper.

This site is where I write about what happens at the boundary between cognition, language, and machine behaviour. The blog posts are regular thinking-out-loud. The labs pieces are something else — interactive, hand-built, designed to be experienced rather than skimmed.

I hike too much, teach when I can, and spend more time than is healthy thinking about consciousness.
