Data scientist, software ninjaneer, creative analyst, former head of CIA, part-time astronaut, triple Olympic gold-medalist (twice), hyphenated-specialist, chief biscuit dunker, habitual dreamer, and all-round nice guy.

I've also been known to tell a few white lies every now and then. :)

I've been using R since it was called r.
