Our skeleton has many important functions, such as defining the shape of the body, allowing us to move around and protecting our internal organs. Whilst fulfilling these functions our bones must carry out one more vital process before we reach adulthood: they must grow in order for us to become taller. How bones grow and are able to keep growing throughout childhood is the focus of our research.
The aim of our research is to better understand bone elongation, and how the population of growth-promoting cells is maintained until we reach our adult height. We focus on understanding the fundamental principles of bone development at the cellular and molecular levels, as well as with more clinically oriented projects.
We encourage enquiries from students wishing to study for higher degrees in skeletal development.
