I am in the Core Data Science group at Facebook. I build statistics tools, develop new ways of analyzing data, and run large online experiments.

When I'm not working on research, I enjoy sailing, traveling, playing the violin, and programming. I developed (and continue to develop) the free, open source race timing software fsTimer, which has been used for timing races around the world. I am also a developer and maintainer of the Prophet time series forecasting package for R and Python.
