AUTHOR INFORMATION

RAKESH KUMAR received his M.Sc. (1984) and Ph.D. (1989) in organic chemistry from the University of Gorakhpur, India. Since 1997, he has been working as a research associate with the Materials Research Program of the National Center for Preservation Technology and Training. Prior to this he was a conservation scientist (fellow) in the Monuments and Sites Conservation Research section of the Getty Conservation Institute. He worked previously as an academic visitor, during 1991 and 1992, at the Institute of Archaeology, University College, London, and from 1987 to 1992 as an assistant chemist in the Science Branch of Archaeological Survey of India. During past years, his research has primarily been focused on the development of new treatments for the conservation of stone monuments and archaeological sites in tropical regions. However, he has also been intimately involved with many other aspects such as preservation of museum objects and site management. His current research interests are in the development and evaluation of consolidants and biocides for stone conservation. Address: NCPTT, NSU Box 5682, Natchitoches, La. 71497.

WILLIAM S. GINELL received his Ph.D. in physical chemistry from the University of Wisconsin in 1949. Since then he has held research positions at Brookhaven National Laboratory, Atomics International, Aerospace Corporation, and McDonnell Douglas Astronautics Company. He joined the Getty Conservation Institute in 1984 as head of Materials Science and currently is head of Monuments and Sites Conservation Research. His principal research interests are conservation in humid tropical environments, stone conservation, seismic stabilization of historic structures, and architectural conservation. Address: Getty Conservation Institute, 1200 Getty Center Dr., Ste. 700, Los Angeles, Calif. 90049.
