Dr. Grusak is a Plant Physiologist at the USDA-ARS Children’s Nutrition Research Center, Houston, TX and a Professor of Pediatrics, Baylor College of Medicine. He joined the Children’s Nutrition Research Center in 1990 to develop an interdisciplinary program that would link plant science and production agriculture with human nutrition concerns. His research involves understanding the molecular mechanisms and regulation of nutrient transport within plants, with the long-term goal of enhancing the nutritional quality of plant foods for human consumption. His group is currently focused on several minerals, including iron, zinc, potassium, and calcium, as well as various health-beneficial classes of phytochemicals such as carotenoids and flavonoids. He also uses in vitro cell culture methods and clinical investigations to study phytonutrient bioavailability and metabolism in humans. His group has developed labeling techniques to incorporate various stable isotopes into plant foods, to provide unique tools for these clinical studies. Dr. Grusak is the 2016 President of the Crop Science Society of America.
