The Food Prices for Nutrition project supports the use of food prices by national governments, international organizations, educational institutions, and civil society, using new diet cost and affordability metrics to transform food systems and achieve global development goals for nutrition and health.
I provide technical assistance to national governments and other stakeholders to monitor access to healthy diets using existing food price data. I work closely with colleagues in Bangladesh, Ethiopia, Ghana, Malawi, Nigeria, and Pakistan. We have developed software tools to support national statistical offices and other researchers to calculate the Cost of a Healthy Diet. I help plan and deliver hybrid and in-person training workshops on the software tools.
