Biomedical Engineering MPhil/PhD

Major code: EGPR/EGMR


Overview

Biomedical Engineering in Liverpool is home to world-class researchers in the fields of macro and micro-biomechanics and biomedical imaging.

Subject Overview

Our areas of interest are generally associated with four research tracks: material characterisation, numerical simulation, topography analysis and medical device development. Although we concentrate much of our effort on applications in ophthalmology, we have strong interests in other areas such as cardiovascular and orthopaedic applications.

We carried out the first comprehensive study of corneal and scleral biomechanical behaviour where we characterised tissue hyperelasticity, hysteresis, anisotropy and viscoelasticity. We developed numerical simulations that embody the ocular globe’s important topographic and material behaviour features, and can predict ocular response to mechanical actions using custom-built analysis software. We have current projects on the automatic analysis of Optical coherence tomography scans and Videokeratography maps.

Our numerical work enabled the study of intraocular pressure measurement techniques and improved their accuracy. We are now leading projects to develop a contact lens device for the continuous measurement of intraocular pressure (for improved glaucoma management), a new air-puff tonometer with reduced sensitivity to variations in corneal thickness and material stiffness, and technologies to measure corneal biomechanical properties in-vivo.

Why Biomedical Engineering in Liverpool?

Facilities

We have an exceptional range of cutting-edge and world-class research facilities and laboratories housed in the main Campus of the University of Liverpool. Our main laboratory includes state of the art, custom-built, ocular inflation test facility with computer control of test method and digital image analysis of mechanical behaviour. We also have the latest tissue preservation facilities, data acquisition systems and material testing equipment to assess tissue viscoelasticity and anisotropy. A recently-renovated Atomic Force Microscopy instrument allows study of the micromechanics of soft and hard tissue. Our group benefits from powerful computing facilities allowing analysis of the nonlinear mechanical behaviour of tissues and organs, inverse modelling of experimental behaviour to derive the properties of tissue material, and the development of programs to create highly detailed numerical models.

Breadth of Study

In addition to a strong research component, postgraduate study in Biomedical Engineering in Liverpool offers training to address the needs of future professional engineers. The collaborative nature of research helps develop professional skills such as team working and leadership, interaction of specialists in other disciplines, coordination of joint activities, presentation in various forms and general communication. Students are encouraged to attend and present their work at conferences in their field. Further oral and poster presentations are organised in the School of Engineering as formal requirements of the degree and parts of activities within research centres and research groups. Written reports, at the ends of the first and year years, form another integral part of the study and provide opportunities to assess progress and handle delays.

Collaboration

Our research in biomedical engineering benefits from a high level of collaboration with clinicians, physicists, material scientists, specialists in image processing and topography mapping, manufacturers and patient group representatives. Our network of collaborators include researchers in the UK, Europe, Australia, the USA and China.
