He is the author of more than 130 scientific papers, has written books on "Genetically Modified Crops", now in its second edition, and on "An Introduction to Bioenergy"; he has edited books on "Protein Phosphorylation in Plants", "Plant Biotechnology", and "Energy Crops". His research concerns the genetics of metabolic regulation in crop plants, how plant metabolism is affected by environmental stress and crop management, and how it can be manipulated to improve crop yield, quality, and food safety. A major strategic application of this work is in reducing the potential for acrylamide formation in wheat, potato and rye products.
