After graduating in Zoology from The University of Reading, UK, Peter Purslow obtained his PhD in the Biomechanics Group, University of Reading working on toughness of extensible connective tissues, and then continued as Leverhulme Postdoctoral Research Fellow in biomechanics.

Moving to the Agricultural Research Council Meat Research institute in 1981, Purslow developed research in the structure and properties of connective tissues associated with skeletal muscle.

From 1991-1995 he was Research Fellow in the Muscle and Collagen Research Group, at the University of Bristol's Department of Clinical Veterinary Science. In 1995 he joined the Connective Tissue Biology Laboratory at Cardiff University's School of Molecular and Medical Biosciences.

He subsequently left the UK for Denmark where, as Professor and Group Leader of Meat Science at The Royal Veterinary and Agricultural University (KVL) in Copenhagen, he continued a wide range of research on muscle and connective tissue structure and properties.

In 2001 he returned to the UK, University of Stirling, Scotland to the Department of Biological Sciences where he was the Coordinator of EU 5th Frame Program Research: Mechanisms of Normal an Pathological Ageing in Extracellular matrices.

Peter Purslow joined the Department of Food Science, University of Guelph, Canada, in January 2003. His current work focuses on cellular mechanisms controlling turnover of connective tissues in muscle and the role of epithelial cell stimulation on in gastrointestinal health.
