I am an applied econometrician, an Associate Professor of Economics at the University of Oxford, a Tutor and Fellow in Economics at Lady Margaret Hall, and a visiting researcher at the Federal Reserve Bank of Chicago.

My research develops statistical methods for untangling cause and effect and applies them to questions in economics and public policy. On the methodological side, my interests include causal inference, instrumental variables, measurement error, spillovers, and Bayesian inference. On the applied side, my recent and ongoing work spans a range of topics from childhood lead exposure to pawn lending.

I am co-founder of SQARE.org, maintainer of restatr, and I blog about econometrics, statistics, and R programming at econometrics.blog.
