AUTHOR INFORMATION

VINCENT OTIENO-ALEGO earned his B.Ed. (Science) and M.S. at Kenyatta University and his Ph.D. in electrochemistry at Queensland University of Technology. His research interests have developed in two principal directions, corrosion science and vibrational spectroscopy. Most recently, his corrosion research has been centered on the use of environmentally friendly corrosion inhibitors in conservation. In vibrational spectroscopy, he is currently using the techniques of Raman and infrared microspectroscopies to study the degradation of plastics and polymer composites, as well as to analyze artists' materials on a number of artifacts. He is a research officer at University of Canberra. Address: Raman Microscopy Unit, Division of Science and Design, University of Canberra, ACT 2616, Australia.

JENNIFER HODGEMAN graduated in 1997 from the University of Canberra Conservation of Cultural Materials Program, Canberra, Australia. On graduating she worked at the Adelaide City Archives as a paper conservator. Since November 1999 she has been working at the National Library of Australia in the digital preservation section. Prior to conservation studies, she worked as a senior technical officer in the field of forensic analytical chemistry. Address: National Library of Australia, Preservation, Parkes, ACT, Australia.

DUDLEY C. CREAGH has extensive experience in the development of new equipment and techniques for investigating photon scattering in the X-ray, optical, and infrared regions of the electromagnetic spectrum. He has been active in the development and use of advanced analytical techniques for the study of problems associated with the conservation of cultural heritage materials in museum custody for more than 20 years. He is expert, inter alia, in the determination of the provenance of important medals (such as the Victoria Cross), Southeast Asian bronzes, and Chinese porcelain of the Ming era. Current research projects include a study of the problems of conservation of aboriginal bark painting and the aging of composite materials.
