Keratoconus (KC) is the most prevalent form of idiopathic corneal ectasia and is characterized by progressive thinning and conical protrusion of the cornea. Depending on ethnicity, KC affects up to one in 450 people and is usually diagnosed in young people at puberty, in their late teens or early twenties. KC is considered a multifactorial disorder but is strongly associated with eye rubbing. Although the aetiology and pathology of the disease is still not fully understood, various microstructural differences have been reported in the literature. While these microstructural differences undoubtedly affect the biomechanical behaviour of the tissue, there is currently very little detailed data available related to altered biomechanics in KC. Obtaining detailed knowledge of biomechanical changes in KC would help improve our understanding of the initiation and progression of the disease. The aims of this project are to:
1. Characterise the anisotropic and viscoelastic behaviour of healthy and KC ex vivo corneas;
2. Develop specimen specific computational models to simulate the effect of eye rubbing;
3. Determine the influence of eye-rubbing and cornea morphology on the progression of KC.
The successful applicant will join the University of Liverpool’s Institute of Ageing and Chronic Disease working in a £40M purpose build facility which houses a range of interdisciplinary laboratories. You will gain experience in experimental characterisation of ocular tissue, optical coherence elastography, electron microscopy and computational biomechanics. You will also gain key, transferable skills in data analysis, scientific writing and presenting to peers as well as lay audiences. Guidance will be provided by the supervisors whose backgrounds are in biomedical engineering, ophthalmology and cell biology.
All postgraduate research students (PGRs) undertake formal, personalised training at the University of Liverpool, co-ordinated by the Liverpool Doctoral College. This creates a learning environment that allows all PGRs to enhance their skills for a successful research experiences and career. You will also be encouraged to attend relevant conferences and apply for conference bursaries and awards, as well as taking part in public engagement activities.
The Institute of Ageing and Chronic Disease is fully committed to promoting gender equality in all activities. In recruitment we emphasize the supportive nature of the working environment and the flexible family support that the University provides. The Institute holds a silver Athena SWAN award in recognition of on-going commitment to ensuring that the Athena SWAN principles are embedded in its activities and strategic initiatives.
Applicants should have obtained (or expect to achieve) a first or upper second class honours degree or a postgraduate degree at merit level in an engineering discipline (e.g. biomedical, mechanical, civil, structural).
