Summary
In this project we will investigate how the light-sensitive cells in the eye (the photoreceptors) use energy and make special pigments that convert light to electrical signals. We will test novel treatments that enhance the energy supply of the photoreceptors in individuals with age-related macular degeneration.

Summary
Glaucoma is an eye disease where elevated pressure within the eye damages the sensitive nerve of sight at the back of the eye. The only current treatment is to lower the pressure in the eye with either drops, laser or surgery. Why the pressure damages the nerve of sight is unclear but there is evidence that it results in a reduced blood flow to the nerve. This starves the nerve of nutrients. We have developed a new treatment that supplies nutrients to the nerve and protects vision.
Life needs energy. We breathe and eat to make the universal biological fuel adenosine triphosphate (ATP). We turn over our own body weight in ATP every day and imbalances in this process lead to severe disorders such as obesity, diabetes and heart disease as well as to ageing. For any real breakthroughs we need to understand the machinery behind biological energy conversion in molecular detail and this is what my laboratory is aiming to achieve.
Antibiotic resistant bacteria cause life-threatening diseases and represent a major public health problem. Globally, drug-resistant infections currently cause over 500,000 deaths annually and this figure is projected to exceed 10 million by 2050. Venom peptides are a new avenue of antibiotic discovery. This proposal aims to define how these peptides interact with the cellular power generator, ATP synthase, to provide a basis for exploiting their potential to treat bacterial infections.

Summary
ATP synthase is the molecular machinery that converts energy derived from nutrients or photosynthesis into the universal biological fuel source ATP (adenosine triphosphate). This is one of the most fundamental processes of life and is conserved from bacteria to plants to humans. Understanding how ATP synthase and its relatives work in molecular detail is expected to have wide-ranging implications for both medicine (in understanding metabolic disorders) and the design of new antibacterial agents.
Bioenergetic Deficit In Neurodegeneration: Studies In Motor Neuron Disease (MND)

Summary
Motor neurone disease (MND) is a fatal neurodegenerative disease. There is no known cause and no known cure. We believe that a defect in the way in which the muscle and nerve cells generate energy to sustain survival causes for there to be added metabolic stress on their already high energetic load, ultimately leading to cell death. This project aims to understand the vicious cycle of energy deficiency that leads to the catastrophic events that cause the death of muscle and nerve cells.
