He earned master's and Ph.D. degrees in Animal Biochemistry from the University of Alberta, Canada.
He completed postdoctoral research in Nutrition and Metabolism (Diabetes and Obesity) at McGill University Faculty of Medicine and in Biochemistry at Memorial University of Newfoundland Faculty of Medicine in Canada.
[2] Much of Wu's research has focused on amino acid biochemistry and nutrition in animals, including the arginine-nitric oxide pathway, as well as the synthesis of the arginine-family of amino acids (including arginine, citrulline, glutamate, glutamine, and proline) and glycine in mammals, birds and fish.
His work has transformed the feeding of livestock, poultry, and aquatic animals worldwide, and also has important implications for human nutrition and health.
Wu has also served as an Editor of "Amino Acids", SpringerPlus: Amino Acids Collection, "Frontiers in Bioscience", "Advances in Experimental Medicine and Biology" (volumes on amino acid nutrition and metabolism in animals), The Encyclopedia of Animal Nutrition, and the Journal of Nutritional Biochemistry.
