Research Topics
The mission of El-Toukhy's research group is to conduct epidemiological, (bio)behavioral, and clinical research to demonstrate the use of mobile technologies to alleviate adverse outcomes associated with modifiable lifestyle behaviors and medical conditions that affect the health and wellbeing of Americans. To achieve this goal, we pursue three interconnected lines of research along the translational continuum – from identifying factors associated with access and use of prerequisite technologies (bench/ discovery), to developing and evaluating digital tools for modifying unhealthy lifestyle behaviors and 24/7 monitoring of disease (bedside/ clinical trials), and wide-scale implementation of those digital health tools for population-level impact through integration with electronic health records (practice/ real-world). We employ mixed methodological approaches, such as user experience, observational and experimental studies, and randomized trials, alongside various study designs such as micro-randomized trials, sequential multiple assignment randomized trials, factorial, and hybrid designs. As digital technologies are becoming a cornerstone to public health and medical care, this research program meets the need to make digital technologies work for all and aligns with national strategic goals of harnessing digital technologies to deliver personalized preventive and treatment programs that promote health, prevent disease, and reduce health disparities.
