    University Position
    Programme Leader

    Interests

    My lab is interested in understanding the mechanisms of mitochondrial homeostasis in relation to neurodegenerative diseases such as Parkinson's disease and motor neuron disease. We use a combination of the powerful genetic techniques of Drosophila and molecular, cell biology and biochemical approaches in mammalian cells. Insights into these mechanisms will deliver a greater understanding of the role of mitochondrial maintenance in the health and dysfunction of the nervous system in a physiological context and will help guide therapeutic development to combat neurodegenerative diseases.
