I am a lecturer at the University of Adelaide (Adelaide, Australia), where I work creating survey weights and thinking about non-representative data, multilevel modelling, poststratification, causal inference, Bayesian inference and all manner of other related fields to making inference from the social sciences.

New preprint with Andrew Gelman and Jessica Hullman. In this paper we discuss the different causal treatment patterns that can result in the same average treatment effect (ATE).
