Research Interest

 

This programme focuses on investigating genetic and acquired causes of sensory disorders to identify potential targets for treatment as well as for preservation of sensory functions during ageing. Animal models and first-line methodologies, such as super-resolution fluorescence microscopy, RNA-seq and proteomics, are used to identify the cellular and molecular mechanisms leading to sensory loss.
