The Biomaterials Research Group studies properties, performance and failure of materials used in medical implants. Focusing mainly on metallic biomaterials such as Ti-6Al-4V and Co-28Cr-6Mo, our group aims to better understand the interactions between the material and the body.

Due to the significant consequences of implant failure, understanding the failure mechanisms and behaviour of materials in the corrosive environment of the body under mechanical loading of daily activities are of paramount importance to mitigate failure of implants and thus improve their longevity.

Metallic components of implants, particularly load-carrying orthopaedic implants (e.g. hip joint implants), may fail as a consequence of mechanical wear and corrosion which is broadly known as fretting corrosion. By-products resulting from fretting and corrosion can lead to aggressive biological reactions with associated soft tissue formation and bone loss; and ultimately risky revision surgeries.


We study the mechanical and chemical behaviour of implant materials and perform an in-depth characterisation of the damage to the implant material from materials science and engineering perspectives. Our investigations include advanced materials characterisation and damage analysis, implant retrieval studies, computational predictions of wear and corrosion, and in-vitro experiments. With the development of metal 3D printing, we also investigate mechanical and surface properties of additively manufactured metals such as titanium alloy (Ti-6Al-4V) for innovative biomedical implants.
