Dr. Constance Gewa is an Associate Professor in the Department Nutrition and Food Studies. Gewa’s research focuses on nutritional status of mothers and children in low-income nations, especially those in Africa. She is a leading expert in estimation of dietary intake quantity and quality in African populations, sustainable food-based strategies aimed at improving food security and nutritional and health status of mothers and children populations in resource-poor settings in Africa and diet-related behavior change. Gewa joined George Mason University after completing her doctoral studies at the University of California Los Angeles. Prior to her graduate studies, Dr. Gewa worked as a nutrition team leader and a research project coordinator with a child nutrition research project in Kenya. A majority of her publications are based on primary data collected from multiple research studies in Kenya. However, she has also utilized secondary data collected from nationally sampled studies in Kenya, and other African nations to further explore nutrition-related factors among mothers and young children. Support for Gewa’s research work has come from multiple sources including the Global Livestock Collaborative Research Support Program (GL-CRSP), Soy Health Research Program, Virginia Department of Health, and George Mason University.
