Yacob is an economist in the International Trade and Development Branch of the Market and Trade Economics Division at the Economic Research Service (ERS). His work mainly focuses on international food security.


Yacob served as a research associate professor at Kansas State University prior to joining ERS. At Kansas State, Yacob led and coordinated the collection of population-based household survey data for tracking the progress, and for the achievement of food and nutrition security programs in northern Ghana. His research interests cover a broad range of topics related to food security, including farm production and income, and the dynamics of labor allocations and employment conditions in farm households; the vulnerability, resilience, and adaptation of farm households and operations to shocks; and the consumption of nutritious and safe food. He has a long-standing interest in the adoption and impact assessment of agricultural technologies, with special emphasis on the adoption of modern crop varieties in the Sub-Saharan Africa and elsewhere. He taught undergraduate classes in global agricultural development and data analytics in agricultural economics.
