Parkinson's disease is one of the major age-related neurodegenerative disorders and is characterized by the progressive loss of neurons over time. Some of the major symptoms of Parkinson's relate to the ability of the patient to initiate or stop movement and these symptoms are related to loss of neurons that express the neurotransmitter dopamine in a region of the brain called the substantia nigra, although other brain regions are also affected throughout the disease progression.

One of the major mysteries about Parkinson's disease and other neurodegenerative disorders is that for most patients the root cause remains unidentified. However, in the last decade several rare families have been found where a disease is inherited whose symptoms overlap with typical Parkinson's disease. Furthermore, common variations in many genes contributes to risk of sporadic Parkinson’s disease.

Our work is aimed at using this genetic information to understand the pathways involved that lead to neuronal damage and death. Specifically, we use a range of molecular, cellular and animal models to look at the effects of mutations on proteins and of variants or missing proteins on cells and on the function of the aging nervous system. We are especially interested in large-scale or unbiased approaches to answer these questions, where possible.
