Hi there!

I am a behavioral scientist focused on improving the design & tech for personal finance and investing. I work at Betterment and PreThink.

I love making new & useful FinTech tools, beautiful data visualiations, science fiction, dogs, and snowboarding.

I studied economics and decision science, finishing my MSc in 2005. I've collaborated on a few academic papers, done a lot of public speaking and press, and some pretty cool coding. You can find me on Twitter and GitHub.

I live in NYC with my wife, kid, and a few bikes.
