Research Description

In birds and cold-blood vertebrates, sensory hair cells of the inner ear spontaneously regenerate following tissue damage, but in mammals this ability has been lost. Why? And could we use regeneration in the human ear to treat certain forms of deafness?
Research in my lab focuses on the molecular mechanisms of sensory hair cell development and regeneration, and the roles of the Notch signalling pathway in these processes. Ongoing projects include the dynamic analysis of Notch activity during hair cell formation and regeneration in the chicken inner ear, and the identification of genes and signalling pathways interacting with Notch signalling during inner ear development.
