About Me

I am an engineering manager at Facebook where I work in the Data Infra org. The org I support operates at the intersection of programming languages and data analysis. In the past, I’ve been part of teams working on a variety of things, including extensions to the Python language and A/B testing.

Before coming to Facebook, some other things I’ve done include:

• In 2013, I worked at MIT on the Julia programming language by helping to create and maintain a few foundational packages for data analysis:
  • DataFrames.jl
  • Distributions.jl
  • Optim.jl
• From 2011 to 2012, I wrote two books for O’Reilly:
  • Bandits Algorithms for Website Optimization
  • Machine Learning for Hackers
• From 2008 to 2013, I was a PhD student in cognitive neuroscience and behavioral economics in Princeton’s psychology department:
  • Measuring Time Preferences
  • Money Earlier or Later? Simple Heuristics Explain Intertemporal Choices Better Than Delay Discounting Does
• From 2004 to 2008, I played in a few bands while working odd jobs:
  • Marigold
  • Dellamorte Dellamore
• From 2000 to 2004, I was a BA student in math at Columbia.
