Katelyn Jison Yoo (Kate) is a Health Economist, and resides in the WBG Analyst Program at the Health, Nutrition and Population Global Practice at the World Bank, covering COVID-19/vaccination and health system strengthening projects and seminal analytical pieces such at the Public Expenditure Reviews (PER), impact evaluations (IE), and Health System Financing Assessment (HFSA). Prior to joining the World Bank, she has worked at UNICEF, UNOCHA, and an NGO based in Kenya, to name a few. She is interested in applying economic thinking and tools to the health challenges faced by low-and-middle-income countries (LMICs), and thus to translate evidence based research into policy actions and inform governments on the best course of action. Kate was born in South Korea and her international framing during her childhood including Indonesia, Malaysia, Canada, Kenya and the US sparks an interest in international development. She is currently finalizing her doctorate in Health Economics at John Hopkins Bloomberg School of Public Health. She holds a master’s degree at Columbia University in Health Economics and Policy, and Business and Economics bachelor’s degree at the University of Toronto.
