The core of Dr. Sorensenâ€™s cancer prevention research is randomized worksite- and community-based studies that test the effectiveness of theory-driven interventions targeting individual and organizational change. These interventions are designed particularly to be effective for low-income, multi-ethnic populations, with the aim of embedding them in the social context in which people live and work. Dr. Sorensen is the Principal Investigator for the Harvard School of Public Health Center for Work, Health and Wellbeing, funded by the National Institute of Occupational Safety and Health. Dr. Sorensenâ€™s research has included a PO1 program project, several UO1â€™s, and multiple RO1â€™s funded by NCI, NIEHS, CDC, and NIOSH, as well as through foundations, including the Robert Wood Johnson Foundation. Her research has included a range of settings, including worksites, labor unions, unionized truck drivers and low-income housing developments. Dr. Sorensen is also studying disparities in tobacco control and consumption in India, and is working with colleagues in India across several worksite settings.
