Gareth Davison is Professor of Exercise Biochemistry and Physiology and Director of Research at the Sport and Exercise Sciences Research Institute at Ulster University in the UK. He holds a BA, MSc, and an MSt in Genomic Medicine from the University of Cambridge and was awarded his PhD in Biochemistry and Physiology in 2002. Professor Davison is a Fellow of the American College of Sports Medicine, and currently serves on several editorial boards, holding Editor roles with the Journal of Sports Sciences, Frontiers in Physiology (Redox Physiology Section) and Antioxidants. His research interests are aligned to exercise, DNA damage and antioxidant function. Recently, his laboratory has focused on bridging the gap between intracellular redox metabolism and DNA methylation in health and disease. James Cobley is a Senior Lecturer in Free Radicals at the University of the Highlands and Islands (Inverness, UK). His doctoral work, completed in 2013, focused on the redox regulation of molecular exercise adaptations in young and old human skeletal muscle. Since then, Dr Cobley has focused on developing methods to measure protein thiol redox state; which has resulted in the development of two new methods: ALISA and RedoxiFluor. Dr Cobley intends, in collaboration with others, to use both technologies to determine if and how protein thiol defined redox signalling regulates exercise adaptations and responses.
