👋 Hi, I'm Geoff.
I get excited about understanding complex systems using data. I also enjoy tinkering with stuff.
Currently, I am a data scientist at Facebook (London) working on measuring, detecting, and preventing various types of harm caused by bad actors on the platform. Previously, I worked at Omio (formerly GoEuro), a Berlin-based, multi-modal travel search and mobile ticketing app.
In my free time, you can find me 🚲 cycling, 📸 taking pictures of stuff, and 🖨️ 3D printing.
