Research in plant genomics, molecular biology, breeding, protein engineering, gene expression, tissue culture. Expression of nutritionally and pharmacologically-active vaccine related products in transgenic crops. Focus on human obesity disorder and food crops such as sweetpotato, peanut and yam. New Technologies: Develop High-Protein and nutritious transgenic sweetpotato and peanut plants with value added traits; develop in-vitro systems for peanut seed production and sweetpotato edible root.
