Andrew Armstrong's current research examines the drivers for revenue generation from user payments for rural piped water services. This work has financial and economic policy implications on a multi-country scale and is foundational to developing viable and equitable tariff policies, attracting sustainable finance and safeguarding lasting water services.

Previously, Andrew spent eight years working for an international engineering humanitarian and development NGO, Water Mission, where he led a global advisory team responsible for sustainable service delivery, behaviour change communication, and monitoring, evaluation and learning. He has led the development and delivery of technical training programs for rural water professionals at the Global Water Center. He is also a core collaborator at Uptime Global, which facilitates results-based funding contracts for reliable rural water services. He holds a MSc in Environmental Engineering and a graduate certificate in global health from the Water Institute at the University of North Carolina at Chapel Hill, a BSc in Mechanical Engineering from Clemson University, and is a professionally licensed environmental engineer in the United States
