Lynne Gaffikin has worked for over 35 years helping to improve maternal and child health in low resource settings. For the past 20 years her work has also extended to the interface between human, wildlife and ecosystem health- most recently including planetary health. She received her doctorate of public health in community health and epidemiology in 1988. Her thesis focused on factors affecting the uptake of family planning in Niamey, Niger. Subsequently, she worked as senior advisor to the Kenya Ministry of Health on a USAID-funded family planning information system project. Starting in 1991, she served as Director of Research and Evaluation at JHPIEGO, a Johns Hopkins University affiliate, focusing initially on family planning training and then, post-Cairo, on broader women’s reproductive health issues. In 1996 she founded her own research and evaluation organization, EARTH Inc., to provide technical assistance to broader ecosystem health initiatives. In this capacity, she has worked closely with numerous conservation organizations (e.g. Conservation through Public Health, Wildlife Conservation Society, Jane Goodall Institute) as a public health and/or research and evaluation advisor. She continues to provide similar technical assistance to NGOs aiming to strengthen human health and environmental conservation linkages. Between 2011-2018, Dr. Gaffikin provided support to INOGO as their health and metrics advisor, undertaking a comprehensive health assessment of the region’s health status, needs and resources and[LG1] advising on strategic planning and results measurement. Currently, she is an Adjunct Professor in the Department of Obstetrics and Gynecology and Affiliate Fellow in the Center for Innovation in Global Health, School of Medicine.
