About the Project
One recent development is the potential use of melanopic lighting. The sleep-wake cycle is controlled by “blue” light that is absorbed by melanopsin photopigment in the retina and signalled to the suprachiasmatic nucleus in the brain via the intrinsically photosensitive retinal ganglion cells (ipRGC). Experimental studies suggest a link between melatonin, sleepiness and performance on cognitive tasks . Allen et al.  developed a special VDU that has 5 spectral channels (rather than the usual 3 of red green and blue), which can present images containing a lot of blue light (high-melanopic) or very little blue light (low-melanopic). They showed that when observers were viewing the high-melanopic display they did not report as much sleepiness as with the low-melanopic display. However there has not yet been an assessment of the effect that this display would have on task performance.
The aim of our proposed project is to identify a set of exemplar cognitive tasks in healthcare work and investigate how performance on these tasks, and associated indicators of wellbeing, are affected by exposure to different types of high- and low-melanopic light. While our primary interest for this project is healthcare applications (and in particular, medicines prescribing, dispensing or administration), we will consider proposals for a project examining work in a different setting.
Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree or equivalent in a relevant subject area (e.g. optometry; psychology; ergonomics/human factors).
For information on how to apply for this project, please visit the Faculty of Biology, Medicine and Health Doctoral Academy website (https://www.bmh.manchester.ac.uk/study/research/apply/). Informal enquiries may be made directly to the primary supervisor. On the online application form select PhD Pharmacy Practice.
For international students we also offer a unique 4 year PhD programme that gives you the opportunity to undertake an accredited Teaching Certificate whilst carrying out an independent research project across a range of biological, medical and health sciences.
