PhD in Addressing Macular Diseases using Ultrathin Digital Optics

Location

Faculty of Engineering and Faculty of Science (Psychology), University of Nottingham, UK

Start Date

October 2026

This PhD offers an opportunity to explore ultrathin metamaterials: a novel type of device that utilises digital and mathematical techniques to design multifunctional visual aids to help address and correct diseases of the eye.

You will work at the intersection of mathematics, physics, AI, and clinical practice through careful design and production of optical metasurfaces, which can help to correct macular degeneration and other eyesight problems through careful control of light.

Why apply for this PhD?

• Work on the next-generation optical physics using metamaterials
• Gain a unique combination of skills in mathematics, machine learning, photonics, and clinical practices in vision.
• Be part of a multidisciplinary research team spanning science and engineering, psychology, and healthcare.
• Access state-of-the-art laboratories and cleanroom facilities.
• Develop skills highly valued in both academia and industry.

Project description

Vision technology relies on careful use of optical components such as lenses. Undoubtedly, standard prescription lenses have been revolutionary in helping billions of people and their quality of life through helping to see more clearly. However, optical technologies are based on standard glass lenses and components which are bulky and have limited capabilities.

Age-related macular degeneration (AMD) affects around 196 million people worldwide and is a leading cause of central vision loss. It reduces the ability to read, recognise faces, and perform everyday tasks, with limited treatment options available for most patients. Existing assistive technologies rely heavily on digital image processing or bulky external devices, which can be expensive, inconvenient, and inaccessible – where simple prescription lenses simply cannot address this.

This project explores a new approach using optical metasurfaces —ultra-thin optical layers that shape light—to enhance vision directly, without electronics. The aim is to increase contrast at object edges, helping users distinguish shapes and details more clearly. While edge enhancement has been shown to improve visual performance in low-vision patients, it is currently achieved using digital systems. This PhD project translates the principle into a compact, passive optical solution.

The project will combine:

• Mathematical modelling and simulation of optical/photonic structures and devices
• Fabrication of ultrathin metasurfaces using the University of Nottingham cleanrooms
• Clinical applications through visual neuroscience approaches
