TITLE: Manipulating carbohydrate availability to enhance exercise induced mitochondrial biogenesis within human skeletal muscle

SUPERVISORY TEAM: Dr Julien Louis, Dr James Morton & Dr Adam Sharples

BIO: Mark is a PhD researcher within the sports nutrition & exercise metabolism research group at Liverpool John Moores University, where his specific research interests focus on the molecular and cellular responses of skeletal muscle to exercise and the role of nutrition in modulating these responses. In addition to his research, Mark also provides nutrition consultancy support to Preston North End Football Club.
