  The overall aim of my research is to gain a deeper understanding of the molecular mechanisms that regulate protein synthesis and protein breakdown in human skeletal muscle. Specifically, I am investigating how amino acid and glycogen availability affects these processes in different populations, including both young and elderly men and women. A wide range of analytical techniques are used to study these mechanisms in both whole muscle and in specific fiber types.

  Ultimately, the aim of my research is to provide new and translatable knowledge that can be used to promote healthy ageing as well as athletic performance.
