Research Interests & Collaborations

I work in two related areas. First, I am interested in the application of study designs, in particular sequential, multiple assignment, randomized trials (SMARTs), and the development of statistical methods that can be used to form adaptive interventions. In this area, I work with Susan Murphy and Inbal Nahum-Shani.

 

I am interested in extending and applying methods for causal inference using longitudinal data sets in which treatments, covariates, and outcomes are time-varying. This includes methods for the analysis of intensive longitudinal data in mHealth. My collaborators on these projects include Susan MurphyBethany Bray, and Donna Coffman.

 

As part of the Institute for Social Research, I participate in a wide variety of social science and treatment/intervention research. I am particularly interested in mental health (depression, sleep disorders), obesity, and substance abuse, especially as related to children and adolescents. If you are a clinical or behavioral health scientist in the early stages of research and study design who is interested in collaborating to design a SMART, please send me an email.
