I am a research scientist in the Core Data Science group. Prior to Facebook, I worked at eBay Research Labs. My main interests are in causal inference, experimental design, and advertising effectiveness. Some of my recent papers include work on imperfect treatment assignment from cookie-level randomization; experimentation in markets with test-control interference; and using sequential testing to shorten experiment duration. I received a PhD in Economics from Stanford University.
