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.
