Reliable Causal Inference

Causal conclusions can fail when instruments are weak or invalid, treatment assignment is endogenous, or important confounders are unobserved. My work develops identification strategies, tests, and estimators for causal effects that remain reliable under these departures, with particular emphasis on instrumental variables, heterogeneous treatment effects, mediation, and observational-study design.
