My major research (around £50million total cash grants and contracts) is in-process measurements on polymers, real time computer control, analysis and computer modelling of polymer processing. I am Professor of Polymer Engineering at the University of Bradford, UK and Director of the internationally recognised Interdisciplinary Research Centre (IRC) in Polymer Science and Technology, with some 30 researchers. I have published extensively - over 300 papers, in scientific journals and international conferences, and have co-authored 9 books, and edited 11 books. I hold 12 patents. My research is internationally recognised, with many keynote addresses and worldwide collaborations (particularly Europe, N America, China, Australia and Japan), and I have developed the UK centre for in-process measurements. Main themes are: (i) analysis/modelling of polymer processing mechanics, involving experimental characterisations of the solid and fluid phase rheology of polymers, with novel rheo-optical, ultrasound techniques and in-process spectroscopy; (ii) processing machinery design and control of processing, especially in the fields of injection moulding, extrusion and reactive processing - encompassing determination of process dynamic responses to the deconvolution of machine and raw material variables for real time closed loop process control; (iii) computer modelling of solid and melt phase processing - used in process design and control (with a licensed polymer orientation process), and for insight into deformation and flow mechanisms - my computer modelling research centre adjoins the experimental laboratory. I have strategically linked all UK academics in cooperative research, as leader or board member: Director of the Polymer IRC, leader of EPSRC major collaborative programme on Enhanced Polymer Processing (£2.7m, 3 Universities and 10 companies), DTI In-process measurements programme (£.25m, 40 companies) and EPSRC Networks for Computer Modelling of Polymer Processing (11 UK Universities and 6 organisations) and (b) In Process Measurements which links 14 UK Universities and a range of organisations); Board member of EPSRC major collaborative programmes on Microscale flows (2.5m, 6 Universities and 6 companies), Faraday Plastics (£2.2m, 4 University groups and industry), and director of MeDe Innovation, the £5.7m EPSRC Centre of Innovative Manufacturing in Medical Devices, founded in 2013 across Leeds, Bradford, Newcastle, Nottingham and Sheffield Universities.

Dr Elaine Brown is a Chartered Mechanical Engineer, with a first degree in Manufacturing Systems with Mechanical Engineering (Bradford) and a PhD in Ultrasonic Monitoring of Polymer Melt Extrusion (Bradford). She has worked in the IRC Laboratories at Bradford for over 20 years, initially as a Research Engineer and now as a University Academic. Her research on in-process measurements has focused on applying ultrasound to measure melt and/or process properties in-line during extrusion, injection moulding and micromoulding, and on methods of measuring polymer melt temperature. More recently her research interests have grown to include the applications of high power ultrasound in polymer melt and pharmaceutical processing. She acts as coordinator for ultrasound techniques within the Centres for Advanced Materials, Micro and Nanotechnology and Pharmaceutical Engineering Science.
Ultrasonic technology provides a robust, adaptable and non-invasive in-process measurement that can be widely applied. Work at Bradford encompasses investigations into extrusion, micromoulding, injection moulding, including GAIM/WAIM, and processes allied to rotational moulding. Ultrasound is a mechanical wave; changes in the velocity, attenuation and reflection coefficients of the high frequency waves are related to the state and conditions of the materials through which they propagate.

Title: A study of the relationship between surface topology and functional characteristics for injection moulded thermoplastic components.

Short description: This project focuses on the creation of 'smart surfaces', which aid in prevention of infection transmission. The core of this project focuses on to use a one step process, micro-injection molding of polymers, in order to create optimised topology on a nano scale; optimisations allow for inhibition of bacterial proliferation, and deter initial bacterial adhesion. Novel techniques for testing and characterisation are being developed in order to incorporate all factors of in-vivo infection outbreak; the self cleaning surfaces are hopefully to be manufactured with ease, and the intended application of said surfaces, is to be used for a large range of healthcare based consumer products.

On graduating with a BA (Hons) in Mathematics and Physics from the University of Keele in 1974, began working at the then British Ceramic Research Association on the mechanical properties of refractory ceramics. This work led on to an interest in the mechanics of solids and to the award of a PhD in 1981. I then took up a postdoctoral position at the University of California at Berkeley to model solid/liquid separation. This was followed by a further postdoctoral position at the University of Leeds in Prof I M Ward's Polymer Physics group, which was later to form part of the IRC in Polymer Science and Technology. I joined the then Department of Mechanical Engineering at Bradford in 1995 as lecturer, continuing to research within the IRC.

At Bradford I have been Principal Investigator on EPSRC funded projects in the areas of polymer constitutive equations, polymer nanocomposites and on surface interactions during polymer processing. Other awards include a European Commission funded project on polymer packaging and three Knowledge Transfer Partnerships. Additionally, there have been a number of commercial contracts with local and international companies.

My research interests are the mechanical behaviour of polymers, including large deformations, deformation processing, interfacial (friction and heat transfer) effects, and fracture. Much of the work involves mathematical modelling using the finite element method. I have developed expertise in incorporating material models into commercial finite element code via user-defined subroutines. Any polymer-oriented problems that would benefit from a modelling, experimental or combined approach are of interest. Most most recent work has covered shape memory polymers and surface interactions in polymer processing. I maintain interests that range from the fundamentals of polymer deformation to technology applied in industry.

I am co-author of two text books:
"An introduction to the mechanical behaviour of solid polymers" I M Ward and J Sweeney, Wiley, 2004.
"Mechanical behaviour of solid polymers" I M Ward and J Sweeney, Wiley, 2013.

These are recommended texts for polymer engineering courses at a number of institutions, for example MIT and the University of Illinois. To date their combined total number of Google Scholar citations is approximately 1,400.

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.
