Research Focus

My focus as a public health nutrition professional is to promote health and address intra-ethnic health disparities among immigrants and US-born populations. My 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 my postdoc at the NIH, I studied cardiometabolic risk profiles and diabetes prediction algorithms among African-born Blacks. I am well versed in nutritional epidemiology and dietary acculturation, specifically among Afro-Caribbeans and Africans living in New York City.
I am dedicated to mentoring the next generation of nutrition and epidemiology researchers and engaging students directly in my research activities including community assessments, shoe-leather neighborhood mapping, electronic health records analysis, and qualitative interviews.
