Summary
Sight relies on the signals of nerve cells in the brain, but we know little about the way in which nerve cells support this, or why in some people sight is diminished. In this work we will measure the signals of nerve cells in the visual pathway to gain knowledge of these processes: we will make measurements in normal animals and in those that suffer from brain disorders. Our work will provide a scientific basis for the diagnosis and treatment of these disorders.
We stand without falling by using silent senses from muscles and the balance organs of the inner ear to unconsciously detect and control our movements. Since the leg muscles provide both the force and the sense, and critically rely on good circulation, they are vitally important. I propose to study how these sensory and muscle functions are used to control balance, posture and stepping reflexes, making it easier to identify older people who will fall and design new preventative strategies.
Mood and anxiety disorders represent a tremendous cause of disability and morbidity. This research will use cutting-edge brain imaging technologies to understand why these disorders typically emerge in young people and whether brain imaging can reliably predict the effectiveness of different treatments for individual patients.
Vestibulo-ocular Reflex Physiology, Pathology And Rehabilitation

Summary
A sensation of movement from the inner ear is used to stabilise vision during head movements. Without it, every time you walk, run, or drive on a bumpy road, the world would appear to bounce. It can be debilitating when this sense doesn't work due to various diseases. This research examines how this sense works normally and the factors important for self-repair after injury. This work will also develop training exercises using a device for take-home balance rehabilitation.
New Insights Into The Mechanisms Of Thrombogenesis In Atrial Fibrillation

Summary
Atrial fibrillation (AF) is the most common heart rhythm disturbance (arrhythmia), which is associated with a high risk of stroke due to clot formation within the left atria. At present we still only have a limited understanding of the mechanism of clot formation in AF. The aim of this study is to determine the critical mechanisms that contribute to clot formation within the left atria in AF. This knowledge is fundamental to the development of more successful interventional approaches.
