• Invented a new system for getting high-quality data from crowd workers on Mechanical Turk and used it to build an app that lets you take a photo of your lunch and see you how many calories you ate. We built a Python/Django framework for breaking up complex tasks into simpler problems and designed a sequence of interfaces for workers to identify foods in a picture, match them with a nutrition database, and measure portions. We ran several studies to prove our system was comparable to experts in accuracy, easier to use than traditional food diaries, and less error-prone than amateur calorie counting. Published in UIST 2011 and cited in 180+ papers so far.
