Version 2I am an Assistant Professor of Statistics and Political Science at UCLA.  My recent research focuses on creating new methods–including both theoretical approaches and new estimation strategies–for identifying and validating causal effects.  I also study survey design methodologies, including a new survey sampling method that reduces reliance on post hoc weighting methods and alleviates non-response bias, and an automated raking methodology that selects the optimal auxiliary vector on which to weight.

In 2012, I ran the polling operation for Obama for America’s Analytics department, which very accurately predicted election outcomes in the campaign’s battleground states.  I also co-founded a successful analytics and technology start-up, BlueLabs, focused on providing analytics services to clients in politics, issues advocacy, healthcare, and education.

I hold a PhD in Political Science and a MA in Statistics from UC Berkeley.  I also completed a Post Doctoral Research Fellowship with at Princeton University.

If you can’t find me around the office, chances are I’m climbing some rocks somewhere.
