Protein metabolism, fatty acid biohydrogenation expert
Manipulation of gut microbial activities

Dr John Wallace is Leader of the Microbial Biochemistry Group, part of the Gut Health Division at the University of Aberdeen Rowett Institute of Nutrition and Health, which he joined shortly after completing his Ph.D. at the University of Glasgow in 1976.  He specializes in the microbiology of animal and human digestive tracts and ruminant nutrition, and his main interests are protein metabolism, fatty acid biohydrogenation and manipulation of gut microbial activities.  Recent work has focussed on fatty acid biohydrogenation in the human colon and protein metabolism and genotoxic products of amino acid breakdown in the human colon.  Dr Wallace has been coordinator of two EC-funded consortia on plant materials as natural alternatives to antimicrobial growth promoters, 'Rumen-up' and 'REPLACE', and is a member of the 'LIPGENE' and 'FEED-SEG' consortia.  He is currently Deputy Editor of the British Journal of Nutrition.  He was awarded the DSM Nutrition Award in 2007 'in recognition of his pioneering research in animal nutrition.'
