Bio

My primary research interest is harnessing adaptive interventions to transform health care. Adaptive interventions address the changing needs of individuals by modifying their treatment based on dynamic information about their state and progress. An important focus of my work is the Just-In-Time Adaptive Intervention (JITAI), a special type of adaptive intervention that leverages powerful mobile and sensing technologies to adapt the delivery of support in real-world settings—in near real-time, as well as interventions that blend human-delivered (e.g., coaching session) components with digital (e.g., mobile-based) components, which necessitates adaptation on multiple timescales. This work is highly multidisciplinary, spanning behavioral health and applied psychology, while also being tightly integrated with advanced research methodology
