 Profile

Dr. Thavarajah is currently leading Clemson University's pulse biofortification research program to combat malnutrition and obesity. Dil started the first USA Pulse Quality and Nutrition Laboratory at North Dakota State University, Fargo, ND, in 2010. Before these positions, Dr. Thavarajah worked at the Canadian lentil biofortification program at the University of Saskatchewan, Canada. Dil is internationally recognized as a leader in lentil biofortification, especially for iron and selenium. Dil advises graduate and undergraduate students and serves as an honorary visiting lecturer, University of Peradeniya, Sri Lanka, and an advisor to the ICARDA Lentil Biofortification program.

 Research Interests

Dr. Thavarajah has a broader interest in understanding the genetic biofortification of lentil, field pea, and chickpea to improve human nutrition. Global nutritional security is one of the primary focuses of this program. The goal is to develop nutritionally enhanced lentil and field pea cultivars for both organic and conventional cropping systems around the world. The nutritional targets are prebiotic carbohydrates, protein quality, minerals (Fe, Zn, and Se), folates, and carotenoids. My program is closely working with ICARDA – Morocco, USDA-ARS – Washington State University, and Nepal Agricultural Research Council (NARC). Dr. Thavarajah leads Clemson University Pulse Crop Quality and Nutrition, Organic Field Pea Nutritional Breeding programs.

Major Grants
1. AFRI-NIFA-OREI: Breeding biofortified field pea for organic systems
2. AFRI-NIFA Foundation: Genomics of lentil prebiotic carbohydrates
3. USDA-ARS-PHI: Improving the nutritional value of chickpea
4. The Good Food Institute: Organic field pea protein ingredients
5. USAID: Feed the Future Innovation Lab for Crop Improvement
