I completed my Undergraduate degree in Physiology at the University of Dundee in 1999. I obtained my MSc in Neuroscience from the Institute of Psychiatry, Kings College London in 2000. Following this I completed my PhD at the University of Glasgow in 2003. My PhD thesis focused on the interactions between Neuropeptide Y and light in the regulation of the master circadian pacemaker. My post-doctoral research has focused on looking at the influences of serotonin on the circadian clock (Smith College, MA, USA) and more recently focusing on retinal physiology and assessing the contributions of photoreceptors in the mediation of non-image forming responses to light (University of Manchester, UK). Currently, I hold a position at the Medway School of Pharmacy as a lecturer in Pharmacology/ Neurophysiology.

My research interests lie within biological rhythms and circadian neurobiology. I am particularly interested in the way in which the mammalian circadian clock, located in the brain, responds to environmental stimuli such as light and non-photic cues which include exercise and feeding. My most recent studies have looked at the neural basis of circadian entrainment and retinal photoreceptor contribution to non-image forming circadian responses. Disruptions of this type of biological rhythm have been shown to result in, amongst others, states of depression, seasonal effective disorder (S.A.D.) and, most recently, the onset of cancer in humans.
Current research projects focus on how light driven responses are interpreted by the retina and circadian clock, from a mechanistic point of view and with regards to possible changes that occur during ageing.back to top
