Biography

My research focuses on using behavioral theory and novel methodologies to develop adaptive interventions, namely interventions that use ongoing information about the individual to modify the type/intensity/delivery-mode of support.

Health Psychology:

Adaptive Interventions
Just-In-Time Adaptive Interventions
Social Support, Stress and Health

Research Methods:

Sequential Multiple Assignment Randomized Trial (SMART) and related data analytic methods for constructing adaptive interventions
Factorial and Fractional Factorial Designs
Multilevel Data Analysis and Experimental Designs for developing behavioral interventions
