The mammalian nervous system is composed of billions of neurons that connect to their targets with remarkable precision and order. Such organisation is an evolutionally conserved feature of the nervous system and underpins its ability to form a diverse array of functioning neural circuits.

The neuroanatomical characteristics that underlie functional organisation are initially formed during embryonic development. However, the molecular and cellular mechanisms that determine embryonic circuit formation remain poorly understood.

We utilise the developing somatosensory system in the spinal cord as a tractable model to study how neural circuits are established during embryonic and postnatal development. Our focus is to explore the molecular and cellular mechanisms that dictate cell body settling position and axonal trajectory and examine the consequences of these anatomical choices for neural connectivity. Our laboratory uses wide range experimental approaches such as mammalian genetics, live imaging, biochemistry, classical embryology, cell and molecular biology.

The work in our group is critical for a general understanding of the developmental circuitry that gives rise to somatosensory perception in animals. The aim is to use this model system to identify fundamental principles in the development of neural connectivity. Moreover, such studies are important in understanding the molecular etiology of nervous system disorders, neural involvement in cancers and is a critical first step for designing strategies to restore function to a damaged nervous system.
