In this role, she serves in leadership across a number of social medicine clinical and education programs including as the founding director of GLOhBAL (Global Learning. Optimizing health. Building Alliances Locally) at Cohen Children’s Medical Center of New York. In this role, she oversees the program’s mission of providing inter-professional clinical and research training in global and immigrant health to fellows, residents, medical students and public health students through established partner sites in Kenya, India and Dominican Republic. Since 2013, the program has served these partners through provision of direct care to over 2500 children; training of over 150 local health professionals and education for almost 100 residents and students. Over the past 13 years, Dr. Uwemedimo has worked as a clinician in sub-Saharan Africa, Asia and Latin America and continues to work in Queens, New York as an outpatient pediatrician, with a focus on ethnic minority children from immigrant families.

As a social medicine researcher, her work focuses on : 1) understanding societal and health system barriers to use of pediatric preventive care services and 2) evaluating implementation strategies of community- clinic partnerships to improve quality of pediatric care and child health outcomes, among children in the US and internationally. In the past, she has received NIH funding to examine determinants of preventive healthcare use among South African children in families affected by substance use and effectiveness of community- based interventions to improve preventive services uptake among Nigerian children living in conflict areas. In 2016, she was named a Health Disparities Scholar at the NIH National Institute of Minority Health and Health Disparities.

In 2017, she created FAMNEEDS, “Family Needs Screening Program”, which is a program that to-date has screened over 1600 families for caregiver psychosocial and socio-economic hardship during well child visits, connects them to social service resources and provides 3-month follow-up and support.  More recently, as a recipient of the Robert Wood Johnson Foundation Clinical Scholars Fellowship she received grant funding to leverage FAMNEEDS to identify housing insecure families, and partner with community based organizations to pilot a community collaborative targeting housing insecurity.

She has been a member of the Global Health National Steering Committees for both the Association of Pediatric Program Directors and the Academic Pediatric Association, and an active member for the Section of International Child Health of the American Academy of Pediatrics. She is a peer reviewer for Pediatrics, Academic Pediatrics, Bulletin of the WHO and Global Health Action Journal.
