Hello there.

I muck about with computers and probability, to better understand humans, and how they behave.

I moved from London to San Francisco in 2014.

I occasionally blog about statistics and hacking — if that sounds interesting, see the Blog section.

If you’re after code, research, or slides, your best bet is the Work section.

Frequently Asked Questions

Q: Is your surname really Rocks?

Yes, although I’m afraid it’s pre-Elvis in origin. It’s from Ireland, and means people that live near some rocks.

Q: What’s a data scientist? It sounds made up.

It is. Data scientists are believed to be statisticians who write computer programmes, but no-one’s certain.
