Andrew Wang leads cost-effectiveness analysis and evidence for OES's investment and program decisions. At Evidence Action, he helped build the organization's cost-effectiveness function and led a team that developed modeling across a portfolio of more than 20 programs, supporting decisions on intervention selection, program design and optimization, geographic expansion, and exit.

His work includes developing organizational cost-effectiveness methodologies and building early-stage models where data is limited, including analyses of RUTF and MMS. He previously worked on global health programming and adaptive learning at Results for Development, and provided advocacy and communications support to the Gates Foundation at Global Health Strategies.

He holds a B.A. in Global Health and a B.S. in Environmental Science from Duke University.
