About Me

I'm a Staff Data Scientist at Netflix, where I work on a variety of strategic initiatives that leverage my expertise in experimentation and causal inference.

Before joining Netflix, I was a Staff Data Scientist at Apple, where I helped to build Siri's A/B testing platform, and a Research Scientist at Facebook, where I worked on missing data problems in ads measurement.

I received my PhD in political science from Princeton University, where I was fortunate to be advised by Rafaela Dancygier and Kosuke Imai. I studied voting decisions and survey methodology, and eventually wrote a dissertation on electoral politics in Europe.

My wife, Katherine McCabe, teaches American politics and data science at Rutgers University.

My resume can be found here.
