Professor Moughan graduated PhD from Massey University in the area of mammalian protein metabolism in 1984. His early research career focused on digestive physiology and the mathematical modelling of amino acid digestion and metabolism in monogastric species of animal, especially avian, porcine, feline and human. Over the last 20 years he has led a systematic discovery-based research programme into the effects of diet on gut metabolism and digestion and, amongst other discoveries, is credited with establishing the role of food peptides in influencing gut protein metabolism. He has also made significant contributions to knowledge in the chemical analysis of foods and the development of bioassays of nutrient availability. The latter have had considerable application in practice. He is widely regarded as a world authority on mammalian protein metabolism and food evaluation science.
Professor Moughan has published some 350 works of scholarship. Of these more than 250 are peer-reviewed publications, with papers appearing in high impact factor journals including: Journal of Biological Chemistry, Analytical Biochemistry, Bioorganic Chemistry, Journal of Nutrition, Journal of Agricultural and Food Chemistry, Journal of the Science of Food and Agriculture, Journal of the Association of Official Analytical Chemists, Journal of Dairy Science, Journal of Animal Science, Journal of Paediatric Gastroenterology and Nutrition, Clinical Nutrition, American Journal of Clinical Nutrition, British Journal of Nutrition.
Professor Moughan has edited three text books and is co-author of two teaching monographs.
In 2010, Professor Moughan was invited by Professor Stipanuk of Cornell University to assume the authorship of the Chapter: Digestion and Absorption of Protein in Elsevier's Biochemical, Physiological, Molecular Aspects of Human Nutrition, one of the world's leading advanced texts in human nutrition.
Professor Moughan's work has received 2,414 citations (Web of Science, May 2010), with 11.66 citations per item on average. Forty-five papers have each been cited more than 20 times and 81 papers each more than 10 times. This is a high citation rate for the field. The world average citation rate for Agricultural and Food Science in 2009 was 4.4 citations per item.
