Dr. Jammer’s work focuses on livestock production systems, farm management decisionmaking, and the development of sustainable agricultural systems, with a strong emphasis on bridging theory and practice. His research is informed by substantial industry experience, including roles as a production manager and livestock farmer, which enables him to ground academic work in the realities of farm-level decision-making. His research centres on improving livestock production efficiency and optimising farm management strategies across diverse production environments. A key aspect of his work involves analysing decision-making at the farm level, particularly in relation to resource use, financial performance, and system sustainability. He also has a strong interest in small-scale farmer development, with a particular focus on enhancing youth participation in agriculture and strengthening rural livelihoods.
