My name is Martin Devaux and I am a third-year PhD student in Political Science at Columbia University. I study political methodology and comparative politics. Prior to my PhD, I was an Associate at IDinsight, and an MPA student at the London School of Economics.
My current methodological interests revolve around the external validity of experiments. You can find here the working paper I co-authored with Naoki Egami on Robustness to External Validity Bias, and here the associated R package. I am separately working on the decomposition of variation in experimental treatment effect across contexts.
My current substantive interests include collective action, group formation, and legislative activity in advanced economies.
