Biography

John has been working as a Biomechanical Engineer in the field of Orthopaedics since 1991 and undertook his postdoctoral fellowship at the University of Vermont, USA - one of the most prestigious international biomechanics research centres. He has authored one book chapter, 20 articles, and presented over 75 papers both nationally/internationally on a wide range of biomechanical topics. His major research interests are to understand the mechanisms of spine disc degeneration/tissue injury, and bone/soft tissue mechanics across their hierarchical scales.

Research interests

John Costi is a Biomechanical Engineer with substantial experience in the conduct of experimental research into Orthopaedic Biomechanics of joints, soft tissue/bone, implants and medical devices. Expertise in the area of the spine and intervertebral disc biomechanics.

His major research interests are to understand the multiscale, complex mechanical behaviour and failure mechanisms of the discs and mechanisms of spine disc degeneration, disc tissue injury and biomechanics, knee ligament reconstruction, soft tissue mechanics and hip implant micromotion.

Multiscale characterisation of soft tissue mechanics

Established materials testing systems exist for medium to large scale determination of the mechanical function for whole biological tissues, implants and medical devices. However, in order to fully quantify the behaviour of tissue structures, an understanding of their structural and mechanical behaviour is required at the nano- and micro-scales. This information, together with macroscopic material behaviour, can be used to develop multi-scale models of tissues that will allow more complex and realistic simulations to be undertaken.

Programs of research are currently being developed at both nano and micro-scales and novel techniques are being developed to measure the micromechanical properties of soft tissue in multiple degrees of freedom.

Hexapod Robot for Biomechanics Testing

A novel design of a Hexapod Robot has been developed within the School in collaboration with the School of Mechanical Engineering, University of Adelaide, to enable complex 6 DOF testing of bones, joints, soft tissues, artificial joints and other medical/surgical devices.

Funding has been obtained by John from Foundation Daw Park, Repatriation General Hospital, the Health and Medical Research Fund, Department of Health, SA Government, as well as the School and the Faculty of Science and Engineering. The current hexapod is based heavily on the very successful Hexapod developed at the University of Vermont by Ian Stokes et al.
