The research focus of our group is on plant mineral nutrition. Our research seeks to increase our understanding of mineral nutrient dynamics in agriculture and food systems. A particular focus is on improving the nutritional quality of crops and the movement of nutrients to humans and livestock diets. This work includes collaborations with soil and crop scientists, human/animal nutritionists, and social scientists. It also includes the development of long-term research and training partnerships with higher education and government research institutes in sub-Saharan Africa (SSA). Recent research highlights include characterising spatial controls of micronutrient deficiencies in Malawi. Since 2017, Martin has held a part-time Senior Research Fellow position (Agriculture & Food Systems) in the Research and Evidence Division of the Department for International Development (DFID), UK.
