BIOGRAPHY +

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.

Previous research projects include:
EPSRC Realising Our Potential Award (ROPA) Application of ultrasonic measurements to injection moulding, including longitudinal and shear wave monitoring(1998-2006)
EPSRC Enhanced Polymer Processing, Grant co-held by the Universities of Bradford, Queen's Belfast and Brunel
Involving development of new measurement techniques for temperature measurement during extrusion and injection moulding, measurement of orientation during extrusion, energy measurements during extrusion and injection moulding and ultrasonic measurements during the cure of thermosetting materials used for Reactive Rotational Moulding.
DTI-funded MPM1.4 In-process measurements
Including development of temperature measurements and ultrasonic measurement of residual wall thickness during gas assisted injection moulding.
VIPps, Science Bridges China and EPSRC Global Engagements programmes
Linking UK and Chinese universities

From 2011-2013 Elaine spent part of her time on secondment as a STEM Fellow in the School of Engineering, liaising with the STEM Office in the University on various activities, in particular curriculum design and widening participation. She retains an interest in Engineering Education, with particular interests in encouraging more girls to engage with engineering and science degrees and to follow a career in engineering.

Elaine completed the Postgraduate Certificate in Higher Education Practice at Bradford in 2010, and was awarded the Certificate with Distinction. She is a Fellow of the Higher Education Academy (FHEA).
