• Biography/ Background

  Di is an applied economist with research experience in agricultural development, food and health economics, and natural resource management. His previous work addresses issues in the Asia-Pacific region, Sub-Saharan Africa, and the United States. His research aims to disentangle the complicated mechanisms linking food, health, natural resources and economic development from both theoretical and empirical perspectives.

  Before joining the Centre for Global Food and Resources, Di has worked extensively with CGIAR centres in Africa and Europe as well as government agencies in the United States. His work has been funded by the Bill & Melinda Gates Foundation, USDA National Institute of Food and Agriculture, and several state government agencies in the United States, and recently by Australian Department of Agriculture, Water and the Environment. He has worked and lived in Australia, United States, Ethiopia, China, Vietnam, Italy, Canada, and Mexico. He has taught advanced impact evaluation methods to doctoral-level economists from several CGIAR centres.

  Di's current research topics include:

  • Agricultural development and welfare outcomes in developing countries
