Research Interests

Trained as an environmental epidemiologist and behavioral scientist, Dr. Poulsen draws upon a broad methodological skillset in her research, including the use of electronic health record data, survey research, mixed methods, and formative and qualitative research. Her research interests center on factors that constrain or facilitate healthy lifestyle behaviors and that influence health outcomes, including socioeconomic determinants of health, psychosocial factors, and the environmental contexts in which we live. Her epidemiologic research considers the impact of these influences on health behaviors and outcomes at multiple levels. For example, at the level of the home, she has investigated how household food insecurity, the home food environment, and parenting practices influence the risk of childhood obesity. At the community level, her research focuses on the impact of the built environment (food, physical activity, and social environments) on diet and physical activity, childhood obesity, and diabetes. At the broader environmental level, she has examined the community health effects of industrial food animal production and the impact of unconventional natural gas development on agriculture, and her ongoing work explores how blue space such as the Susquehanna River affects health and wellbeing. Her ultimate goal is to integrate understanding of the connections between social and environmental contexts and health into community- and clinical-based preventive care and healthcare delivery. Toward this end, Dr. Poulsen works with colleagues in the Obesity Institute on intergenerational behavioral intervention trials that translate research into practice to prevent pediatric obesity, drawing upon her prior experience adapting and implementing community-based prevention interventions.
