Professor of Cell Biology
King's College London
I completed a PhD in muscle regeneration at King’s College London, before working on gene regulation and heart development with Professor Margaret Buckingham at the Pasteur Institute (Paris, France). Next, I worked with Professor Terence Partridge investigating muscle stem cells at Imperial College London, before starting my own group at King’s College London in 2005.I completed a PhD in muscle regeneration at King’s College London, before working on gene regulation and heart development with Professor Margaret Buckingham at the Pasteur Institute (Paris, France).

My core research is directed at understanding how muscle stem cells are regulated in healthy and diseased skeletal muscle, and cancer.
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. The functional unit of skeletal muscle is the muscle fibre: 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. In muscle wasting diseases such as muscular dystrophies though, this regenerative capacity is gradually degraded.
Current research in the group includes investigating the contribution of stem cell dysfunction and mechanisms of disease progression in Fascioscapulohumeral muscular dystrophy and Emery-Dreifuss muscular dystrophy, together with developing potential therapies.
