Research Interests & Collaborations

I am working on multiple related projects all aimed at how best to collect and use data in the development of adaptive interventions. My collaborators on these projects are Daniel AlmirallLinda Collins, and Inbal Nahum-Shani.

 

My current primary interest concerns clinical trial design and the development of data analytic methods for informing multi-stage decision making in health. In particular for (1) constructing individualized sequences of treatments (known as adaptive interventions) for use in informing clinical decision making and (2) constructing real-time individualized sequences of treatments (known as just-in-time adaptive interventions) delivered by mobile devices. (See workshop on just in time adaptive interventions.) Adaptive interventions, also known as dynamic treatment regimes, are composed of a sequence of decision rules that specify when to alter the therapy and specify which intensity or type of subsequent therapy should be offered. These regimes hold the promise of maximizing treatment efficacy by avoiding ill effects due to over-treatment and by providing increased treatment levels to those who can benefit. 

 

My work has been funded by the National Institute on Drug Abuse and the National Institute of Mental Health.
