Dr Pete Twigg

BIOGRAPHY +

Pete Twigg heads the Medical and Healthcare Technology programme team at Bradford and is deeply involved with the development of healthcare science and technology education programmes at a national level. His research interests lie in the application of mechanical analysis to biological systems, ranging from organic molecules and cells to prosthetics and human movement.

The biomaterials aspects of this work are largely conducted in the Bradford University Medical and Polymer Engineering Research (BUMPER) characterisation laboratory, which he heads. This facility has an atomic force microscopy suite with Dimension 3100 and MultiMode microscopes, as well as nanoindentation and PicoForce mechanical characterisation. The laboratory is a multi-user facility with a host of characterisation equipment and also houses a category 2 biological containment room. Current projects include cartilage characterisation and the development of cartilage substitutes, as well as cell adhesion studies.

Orthopaedics and prosthetics mechanics have been a research interest for some time, including joint replacement, fracture fixation, orthotics and lower limb prosthetics. Techniques vary from friction and wear simulation and testing, through pseudo-static and dynamic mechanical testing, to 3D kinetic analysis. The kinematic and kinetic work is largely done using an 8 camera Vicon motion capture system, which has also been applied to pre and post-operative clinical subjects and investigation of the role of vision in negotiating obstacles, among other studies. Physiological measurement, such as electromyography, has also been linked to some kinetic studies, such as the investigation of fatigue effects.
