Research Theme

• Synapses, Circuits and Behaviour  
• Injury and Repair

Research

The somatosensory system endows us with a strong tactile connection to the external world in tandem with a pain warning system to protect us from harm. This enables us to safely interact and richly experience the world and loved ones. My research focusses on injury-induced plasticity of this system that drives chronic pain conditions and also neurodevelopmental disorders in which there is a perturbation of this system. My lab’s research on somatosensory neural circuits spans from synaptic analysis to whole animal behaviour and is integrated within the ‘Synapses, Circuits and Behaviour’ theme within the Centre for Discovery Brain Sciences. I am also a member of the Simons Initiative for the Developing Brain and the Edinburgh Skin Network.

Chronic Pain:

Chronic pain conditions are poorly managed with current treatment options having abuse potential (opioid crisis). A better mechanistic understanding of the underlying circuits and plasticity is required for future analgesic drug development. My lab investigates this plasticity using anatomical, electrophysiological and behavioural approaches in preclinical models with a key focus on peripheral nerve and spinal processing. This research is conducted in both sexes because females are more likely to suffer from pain conditions and experience more severe pain with evidence, including our own, suggesting sex differences in underlying mechanisms.

Neurodevelopmental disorders:

In neurodevelopmental disorders there can be perturbation of the somatosensory system with altered tactile and pain reactivity. The somatosensory system undergoes substantial postnatal development and my lab is researching the impact of neurodevelopmental gene mutations on the development and function of somatosensory circuits using anatomical, electrophysiological, optogenetic and behavioural approaches.

Molecular mechanisms of myelinated axon function:

This collaborative work with Professor Dies Meijer investigates the molecular mechanisms that regulate the development of and localisation on ion channels within myelinated afferents that is essential for peripheral nerves to communicate information about the external world and our interaction with it.
