Research interests

Skeletal muscle is an archetypal adult stem cell model, in which maintenance, growth and repair of functionally specialised post-mitotic cells is achieved by recruitment of undifferentiated precursors. My core research has been directed at understanding how muscle stem cells are regulated in healthy, aged and diseased skeletal muscle. The functional unit of skeletal muscle is the myofibre: a giant syncytial cell maintained by hundreds of post-mitotic myonuclei. The routine needs for myonuclear homeostasis, together with the more sporadic demands for hypertrophy and repair, are performed by muscle satellite cells. These resident stem cells are normally mitotically quiescent in mature muscle, and so must first be activated to undergo extensive proliferation to generate myoblasts that eventually differentiate to provide new myonuclei.

The main themes of the group at King’s College London currently include investigating the transcriptional and signaling control of satellite cell activation and cell fate choice, together with examining pathomechanisms and potential therapies for Emery-Dreifuss muscular dystrophy and Fascioscapulohumeral muscular dystrophy, and in cancers such as rhabdomyosarcoma.
