ERIC F. HANSEN graduated from the University of California at Irvine in 1980 with an M.S. in organic chemistry and joined the Getty Conservation Institute in 1985. In his current position as an associate scientist he is pursuing his interests in the environmentally induced deterioration of synthetic and natural organic materials (including collagen, fibroin and keratin), the conservation of ethnographic and archaeological objects, and the analysis of the effects of treatment parameters on the final physical and optical properties of treated objects. Address: Getty Conservation Institute, 4503 Glencoe Ave., Marina del Rey, Calif. 90292.
STEVE N. LEE graduated from University of California, Los Angeles, in 1991 with a B.S. in biology with a molecular, cellular, and developmental emphasis. He was employed as a student assistant at the Getty Conservation Institute for three years. He is now currently attending Dartmouth Medical School and hopes to specialize in cardiology. Address: Dartmouth Medical School, Hanover, N.H. 03755.
HARRY SOBEL is an investigator of the biochemical process of in-vivo aging with more than 150 publications mainly concerning the effect of age on collagen and connective tissue. He is currently a research associate in the Isotope Laboratory, Institute of Geophysics and Planterary Physics, University of California, Los Angeles, and for the past four years he has been a consultant to the Getty Conservation Institute on the preservation and deterioration of proteinaceous materials. Recent work has focused on residual proteins in historic bone. His interests include the effect of the environment on proteins under ambient conditions and the analysis of proteins for conservation, art historical, and archaeometric interests.
