About this site

Hi, you’ve found my website! I don’t update this very often, but I do try to occasionally collect my thoughts here on topics I find interesting. Most of the time, that means nerding out about urban transport topics, or data visualization on the web. Or maybe about my travels around Europe.

Who is Billy?

I’m an American living in Berlin, Germany. My current research position at Technische Universität Berlin focuses on data visualization for the MATSim transport simulation framework. MATSim is amazing, it can do anything – right now it’s getting a lot of attention for its ability to simulate traffic scenarios for the impending doomsday arrival of fleets of robot cars.
