Research Interests

My interest is in understanding the cellular and molecular basis of synapse formation in the mammalian nervous system. Synapse formation is critical for the formation, maintenance and plasticity of the nervous system and perturbations in synaptic structure and function have been implicated in a range of neurological disorders. My research focuses on cholinergic synapses that play critical roles in the functioning of both the peripheral and central nervous systems. Our main aims are (1) to define the extracellular synaptogenic factors that regulate the formation and maintenance of neuromuscular and neuronal autonomic synapses in the PNS, and (2) to define the intracellular mechanisms that regulate the trafficking and localization of nicotinic acetylcholine receptors at these synapses. This includes collaborative studies with clinician-scientists at UCD to establish how defects in synapse formation or receptor localization contribute to neurological diseases such as myasthenia gravis and congenital myasthenic syndromes.
