Profile

Dil Thavarajah is a Professor at Clemson University Department of Plant and Environmental Sciences. Dil is leading Pulse Biofortification and Nutritional Breeding program. She also co-leads the Phenomics component of the Feed the Future Innovation Lab for Crop Improvement at Cornell University. Before her current position, Dil worked at the Canadian lentil breeding and biofortification program at the University of Saskatchewan, Canada. She started the national Pulse Quality and Nutrition Laboratory at North Dakota State University, Fargo, ND, to support the US Pulse industry's nutritional marketing. Dil is internationally recognized as a leader in pulse biofortification, especially for iron, zinc, and selenium. Dil serves as an honorary visiting lecturer at the University of Peradeniya, Sri Lanka, and a key research partner to the International Center for Agricultural Research in the Dry Areas (ICARDA) to release biofortified lentil cultivars for Africa and Asia.

Research Interests

I am interested in finding whole-food-based solutions to combat global “hidden hunger” - micronutrient malnutrition, obesity, and overweight. Major research areas are (1) Pulse Breeding for Nutritional traits (Biofortification): Organic pulse crop nutritional breeding – developing organically biofortified dry pea, lentil, and chickpea cultivars for SC and NC (NIFA-OREI); International Agriculture Development – Phenomics (micronutrient enrichment) - increase micronutrient concentration and bioavailability - iron, zinc, selenium, carotenoids, vitamin B, folates in lentil, field pea and chickpea; understand the different forms of phytic acids types benefit to humans and plants to increase phosphorus bioavailability (USAID; USDA-ARS for chickpea); Organic Plant Proteins: developing pulse protein ingredients with balanced amino acid profiles (the Good Food Institute, FoodShot Global); (2) Prebiotic Carbohydrates and Gut Microbiome: Pulse crops used as a whole foods to reduce obesity, and identify obesity metabolic biomarkers using animal models and cell cultures, and (3) Food Systems towards global food security: Developing sustainable food systems to provide daily dietary needs using pulse crops, roots, and Brassica vegetables. Current food system efforts - Tiger Gardens” and ‘Lunch Box.” Global food security research collaborators are the International Center for Agricultural Research in the Dry Areas (ICARDA), Morocco and India; HarvestPlus; Nepal Agricultural Research Council (NARC); University of Peradeniya, Sri Lanka.
