About the Project

Lead Institute / Faculty: Clinical and Experimental Sciences/Medicine

Main Supervisor: Dr J. Arjuna Ratnayaka

Other members of the supervisory team: Professor Andrew J. Lotery and Dr Helena Lee

Amount of stipend and fees: The first year at £16,062.00 increasing each year for three years at UK Research and Innovation (UKRI) rates. Due to funding restrictions this position is only open to UK applicants.

Duration of the award:  Full-time for three years from 1st October 2022 until 30th September 2025

Project description: Applications are invited for an exciting new PhD studentship funded by Sight Research UK. Age-related macular degeneration (AMD) is a complex blinding disease, where a combination of genetic and non-genetic risk factors, such as an unhealthy diet, results in the irreversible loss of central vision. The project builds on our published work to elucidate the molecular pathways of damage to the retinal pigment epithelium (RPE) and associated tissues in the outer retina. The student will use a combination of in-vitro cell as well as mouse models and must be willing to work with mice. Techniques such as cell and molecular biology, histology, biochemistry as well as imaging will be used for the project. Non-invasive retinal scans will also be obtained from living mice. Potential discoveries could provide new information on diet-induced disease pathways in the retina that predisposes individuals to AMD, and whether such effects could be reversed through better nutrition. This knowledge could also inform public health campaigns, thereby help reduce the burden of sight-impairment and blindness in the UK. The successful applicant will join a dynamic research team consisting of undergraduate/postgraduate research students and postdocs. The candidate is expected to be highly motivated with an excellent work ethic.
