Holley Research Center for Agriculture and Health as a plant physiologist.  His research has mainly focused on micronutrients aimed at at understanding their movement from soils to plants to animals and humans.  He has been very interested in understanding the factors that control the bioavailability of micronutrients in food crops to humans.  Currently, he has been striving to develop close links between agriculture, nutrition and human health to find sustainable solutions to malnutrition through using agricultural tools.  One of his current efforts is with the global CGIAR HarvestPlus program directed at improving the bioavailable amounts of iron, zinc, selenium, iodine and provitamin A carotenoids in edible portions of staple food crops through plant breeding strategies.
