JIM McGREEVY has been head of conservation at the Ulster Museum, Museums and Galleries of Northern Ireland, since 1991. He received a Ph.D. in geography from the Queen's University Belfast in 1982 and held postdoctoral positions at University College London and the Institute of Irish Studies, Belfast. From 1984 to 1991, he was a research assistant at the Public Record Office of Northern Ireland, where he had responsibility for the paper conservation section. He is currently an Honorary Research Fellow in the School of Geography at Queen's University. His research has focused mainly on relationships between stone properties and susceptibility to weathering under various environmental conditions. Address: Department of Conservation, Ulster Museum, Museums and Galleries of Northern Ireland, Botanic Gardens, Belfast BT9 5AB, Northern Ireland, United Kingdom
PATRICIA A. WARKE is a lecturer in geomorphology at the School of Geography, Queen's University, Belfast. Her Ph.D., which was awarded in 1994, involved field study of rock weathering in the deserts of the Southwest United States. From 1994 to 1999, until her appointment as lecturer, she held a postdoctoral position in the School of Geography, which mainly entailed investigation of stone decay on historic structures in urban environments. Research interests are primarily focused on microenvironmental controls on rock weathering in both natural and built environments and the role of exposure history on contemporary stone decay exemplified by recent work on deterioration of newly excavated archaeological stonework. Address: School of Geography, Queen's University Belfast, Belfast BT7 1NN, Northern Ireland, United Kingdom
BERNARD J. SMITH is professor of tropical geomorphology in the School of Geography, Queen's University, Belfast, where he has worked since 1979. Previously, he lectured in northern Nigeria after obtaining both his undergraduate degree and Ph.D. at the University of Reading, England. His main research interest is the study of stone decay processes in natural and built environments. He has published widely on desert weathering, on deep weathering in the humid tropics, and on the weathering of limestones around the Mediterranean. Work on urban stone decay, particularly related to salt damage, has encompassed studies in Venice, Budapest, Rio de Janeiro, Dublin, and, in particular, Belfast. Address as for Warke
