Howell Edwards is Professor Emeritus of Molecular Spectroscopy at the University of Bradford. He read Chemistry at Jesus College in the University of Oxford and after completing his B.A. and B.Sc. degrees he studied for his doctorate in Raman spectroscopy at Oxford with Dr Leonard Woodward and then became a Research Fellow at Jesus College, University of Cambridge. He joined the University of Bradford as a Lecturer in Structural and Inorganic Chemistry, becoming Head of the Department of Chemical and Forensic Sciences, and was awarded a Personal Chair in Molecular Spectroscopy in 1996. He has received several international awards (Sir Harold Thompson Award;

Charles Mann Award; Emanuel Boricky Medal; Norman Sheppard Award) in a spectroscopic career which has resulted in the publication of over 1350 research papers in Raman spectroscopy and the characterisation of materials, along with six books on the application of this analytical technique to art, archaeology and forensic science. He has had a lifelong interest in porcelains and the industrial archaeology , excavation and the preservation of early porcelain manufactory sites , many of which have now disappeared in urban expansion .He has authored six major books on porcelains and has also produced several monographs on the manufactories at Swansea and Nantgarw and the people associated with them. Howell Edwards is Honorary Scientific Adviser to the de Brecy Trust on the scientific evaluation of their artworks and paintings. 

Christopher J. Brooke studied for a BSc (Hons.) in Archaeological Sciences at the University of Bradford, specializing in geophysics, environmental archaeology, and palaeopathology, followed by a PhD at the University of Nottingham in the field of archaeological remote sensing for historic buildings analysis. He has worked in a wide range of organizations from central and local government, through university teaching appointments and industry, a major charity, and freelance consultancy. A Fellow of the Society of Antiquaries, a Fellow of the Royal Historical Society, an Associate Fellow of the Remote Sensing and Photogrammetry Society, and a member of many professional organizations both nationally and in the U.K. East Midlands, he serves on a large number of advisory boards and committees. Dr Brooke's principal research specializations are in electromagnetic remote sensing, nondestructive archeological site survey, record photography, mathematical image processing, environmental study, spectroscopy, the history and archaeology of churches, and the recording and conservation of historic buildings. He has lectured extensively at academic institutions throughout the

U.K. and is currently Honorary Associate Professor in Medieval History and Church Archaeology at the University of Nottingham, and Visiting Fellow in Remote Sensing at Nottingham Trent University.
