University of CambridgeIf identification theory is my research topic, finding new ways to identify causal effects under unobserved confounding is its theme. The theory I'm interested in suits causal questions with difficult confounding structures, not only in economics. While all my results are nonparametric and easy to use with machine learning methods, they also have simple linear model equivalents. Currently, I am a fourth year PhD candidate at the University of Cambridge.
