Erosive Wear of the Teeth: Characterisation of a subsurface layer formed on eroded enamel. Characterising Subsurface Eroded Enamel (CHASE)
Closing date
Disciplines and Techniques
Prof David Bartlett,, Head of Prosthodontics and Graduate training, King's College London
Project Details

Are you interested in pursuing a PhD in a cutting-edge topic that combines dental research and industrial innovation? Do you want to join a world-class team of experts in tooth wear and work with leading chemists from Unilever? Do you want to access state-of-the-art facilities and equipment at Kings College London, Unilever R&D Port Sunlight, and the Materials Innovation Factory? If yes, then this fully-funded (home fees) PhD studentship is for you!

About the project

Erosive tooth wear (ETW) is a common condition that affects the surface and subsurface of enamel, causing aesthetic and functional problems. However, the extent and nature of the subsurface damage caused by acid challenges is not well understood, as most research has focused on surface measurements or polished specimens with little focus on the subsurface layers of affected enamel. This project aims to explore the pathophysiology of ETW by using novel imaging techniques and automated methods to characterise the subsurface structure and properties of enamel after erosive challenges. This will provide new insights into the mechanisms and prevention of ETW, as well as the potential for developing or enhancing treatments that protect the enamel from ageing.

About the studentship

This PhD studentship is funded by the BBRSC and Unilever Research & Development, and will be supervised by Prof David Bartlett, Dr Rupert Austin, and Dr Saoirse O’Toole at Kings College London, and Dr Gareth Owens from Unilever. The successful candidate will be based at the Dental Institute of Kings College London, the biggest and top-ranked dental school in the UK and the world, and will also have the opportunity to visit and work at Unilever R&D Port Sunlight and the Materials Innovation Factory at the University of Liverpool. The studentship covers tuition fees, a stipend, and travel expenses for the duration of the project (3-4 years).

About the candidate

We are looking for a motivated and enthusiastic candidate who has:

  • A first-class or upper second-class degree (or equivalent) in a relevant discipline, such as dentistry, materials science, chemistry, physics, or engineering.
  • A strong interest and background in dental research, especially in tooth wear and enamel.
  • Experience or willingness to learn advanced imaging and analytical techniques, such as SEM, TEM, XRD, Raman, FTIR, etc.
  • Experience or willingness to learn automated and robotic methods for enamel treatments and measurements.
  • Excellent communication and interpersonal skills, and the ability to work independently and as part of a team.
  • A passion for innovation and collaboration with industrial partners.


If given the choice between LIDo and any other doctoral training program, I choose LIDo every time

Alexandra Richardson

The LIDo Programme has revolutionised my view of modern biomedical research. It pushed me to step outside of my comfort zone and to explore research areas which I never considered to enjoy beforehand. My PhD project made me look at large biological datasets in a computational way and I do not regret a single thing I learned on my deep learning journey

Kristina Ulicna

LIDo cultivates a close relationship with the wider life sciences and technology industries to advise upon and guide our outreach activities and student awareness of tracks outside of academia, including entrepreneurial opportunities.

Dr. Renos Savva

LIDo was perfect for me, because of its interdisciplinarity and the opportunities it offered!

Dr. Pedro Almada

LIDo helped me discover a new career path and learn new skills, that I never thought I would be interested in. LIDo has encouraged me to take more risks and experience new sides of research.

Sarah Aliko

LIDo provides a fantastic training environment for cross-disciplinary research

Dr. Viji Draviam

LIDo is like a huge extended family, everyone is willing to help each other out and offer advice which is particularly important when you’re faced with challenges in your research!

Justine Pearce

The best decision I ever made!

Isabel Fletcher

I never thought debating would be helpful to a researcher, but after a LIDo provided debate workshop I felt much more comfortable answering questions at a recent conference!

Freddy Sarathchandra

LIDo gave me the confidence to pursue a PhD in a field I would never have considered before. The sense of community the programme has to offer is second to none, fostering solid friendships and providing a platform to encourage one another along our journeys, both in and out of the lab.
