My primary research interest is achieving a better understanding of the interaction between sensory and motor mechanisms within the visual system. For example, the prevalence of myopia has increased dramatically in the general population, and a growing body of evidence strongly suggests that overaccommodation ('near-work' ) and/or accommodative dysfunction play a role in this increase. Therefore, over the years, one aspect of my work has been centred on defining and stimulating the central near response pathways, including vergence and the pupillary light reflex, in order to better understand the interrelationship between accommodation and refractive development of the eye.
In addition, I have more recently been pursuing other active areas of research interest, including studies of the effect of environmental influences, such as stress, on an oculomotor pathology, congenital nystagmus. Any resultant changes in the frequency and/or size in the continuous eye movements characteristic of this syndrome can have profound consequences on certain aspects of visual performance and perception, thus impacting on the everyday lives of those with this condition.
My collaborations, both in the UK and internationally, have ranged from an assessment of nerve fibre layer damage in an experimental model of glaucoma to investigations of the role of the hippocampus in spatial navigation and visual discriminations. We have just received funding to investigate the remarkable ability of birds to sense and orient with respect to the earth’s magnetic field. My team currently comprises two postdoctoral research associates and five postgraduate students.
We are supported principally by grants from the Leverhulme Trust and the Wellcome Trust, and our laboratories include state-of-the-art histological and neuroscience laboratories, a suite of videomicrographic image processing workstations, and an eye movement facility that includes both several relatively non-invasive infra-red recording systems.
