I develop clinical trial designs and data analytic methods for informing sequential decision making in health. In particular I focus on methods for constructing real time individualized sequences of treatments (a.k.a., treatment policies or Just-in-Time Adaptive Interventions) delivered by mobile devices. This is an area of Precision Medicine. I develop new clinical trial designs (designs in which each person is randomized 100s or 1000s of times) and generalize reinforcement learning algorithms to analyze the data and construct treatment policies. I also generalize data analytic method from causal inference for use in analyzing mobile health data.
