Welcome. I am a political methodologist specializing in statistical text analysis with applications to legislative politics (ideal point estimation, government opposition conflict), political economy (central banker preferences, determinants of inflation expectations), and public policy (the causal inference of racial bias in policing). You can read about all that on the publications page, in the trusty CV, or just that one time in the New York Times.
I'm a Senior Research Scientist at the Hertie School in Berlin. In fact, I'm the Senior Research Scientist at Hertie School, since they just admitted they don't have any other ones. This makes me very special - even specialer than being a Senior Research Specialist back at Princeton because there were quite a few of those. I just thought you ought to know that.
You can sometimes find me wittering on Twitter, writing code on GitHub, or answering questions on stats.stackexchange.com. There's a blog here too, though I no longer quite remember why. If you're wondering if you know me from somewhere, you can ponder some biographical information or take a look at this picture taken a few years ago in my natural habitat (corduroy).
Jonathan Mummolo, Dean Knox and I have a new paper on how not to estimate racial bias in policing. Here's the American Political Science Review version. And here's a preprint, if you don't have access to the journal.
You should read it if you're interested in any subset of: policing, bias, potential outcome wrangling, tricky DAGs, fiendishly clever bounds, and economists being confused.
