Horlyck-Romanovsky, Margrethe, DrPH

A public health nutrition professional committed to health promotion and addressing intra-ethnic health disparities among immigrants and US-born populations. Her mixed-methods research examining intra-ethnic risk profile research in New York City, compares risk factors, health behaviors, and disease profiles of African Americans, African-born Blacks, and Afro-Caribbeans. During her postdoc at the NIH, she studied cardiometabolic risk profiles and diabetes prediction algorithms among African-born Blacks. She is well versed in nutritional epidemiology and dietary acculturation, specifically among Afro-Caribbeans and Africans living in New York City.
Dedicated to mentoring the next generation of nutrition and epidemiology researchers she engages students directly in her research activities including community assessments, shoe-leather neighborhood mapping, electronic health records analysis, and qualitative interviews.
