Dr. Raposo’s research focuses on longitudinal studies of diet quality and cardiovascular disease (CVD) among individuals with hypertension. She is particularly interested in four dietary patterns: the alternate Mediterranean diet, the alternate Healthy Eating Index 2010 (aHEI-2010), the Dietary Approaches to Stop Hypertension (DASH) score and the healthful Plant-based Diet Index. She is currently working with data from the Health Professionals Follow-up Study and the Nurses’ Health Study. Alongside with Dr. Raposo’s work on diet quality, she is also involved in a study investigating the role of dietary flavonoids on the risk of CVD among individuals with hypertension and hypercholesterolemia.

During Dr. Raposo’s Ph.D. studies at Karolinska Institutet in Stockholm, Sweden, she worked with the development and validation of web-based dietary assessment methods as well as with prospective cohort studies on dietary intake and upper respiratory tract infection.
