Prof. Smith is Professor of Tropical Geomorphology in the School of Geography, Archaeology and Palaeoecology 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 and he is a member of the Weathering Research Group within Queen's. He has published widely on natural rock weathering in the humid tropics, hot deserts and around the Mediterranean. Work on urban stone decay, includes studies in Venice, Budapest, Prague, Rio de Janeiro, Dublin and Belfast and he has acted as an adviser to the Getty Conservation Institute on salt damage to buildings. Collaboration with leading conservation architects (Consarc Design Ltd) has included UK Research Council projects to examine how pollution modifies stone surfaces, a study of what makes stonework prone to rapid, catastrophic decay – and what can be done to turn it off – and a project to understand the long-term behaviour of stone in different environments within Northern Ireland that won a UK national award for technology transfer. He is the joint leader of a project to establish a ‘Natural Stone Database' for Northern Ireland, recently completed a major EPSRC funded project to investigate the rapid decay of building limestones, and heads up the current project on understanding climate change and the ‘greening’ of masonry.
Practical collaboration has included inputs into the conservation of key structures in Belfast such as the Albert Clock, St George's Market, Stormont and the Lanyon building at Queen's. These links lead to the creation of a joint venture company ‘Stone Conservation Services Ltd' that combines the practical expertise of Consarc with the research potential of the University. These interests in the conservation of built heritage are complemented by a concern for natural heritage. He is a former member of the statutory advisory Council for Nature Conservation and Countryside (CNCC), and is still a co-opted member of their working group on planning and protected landscapes. He sits on the management committee of the Giant's Causeway World Heritage Site, has a particular interest in the promotion of National Parks within Northern Ireland, sits on the interdepartmental committee to formulate National Park legislation for Northern Ireland and has acted for IUCN as a referee for natural World Heritage Site inscription.

Dr. McAlister is a Senior Research Fellow, an analytical chemist, and a key member of the Weathering Research Group with specialist expertise in the geochemistry of weathered materials. He has been actively involved in Weathering Group projects for over fifteen years, especially the modification of standard analytical techniques for the analysis of building materials, e.g. X-Ray Diffraction for clays and salts in very low concentrations, statistical discrimination of elemental concentration and depletion during weathering and selective extraction to assess differential mobility of weathering products. In the current project, he oversees analytical procedures and provides expertise in the chemistry of stone decay.

Dr McCabe's research focuses on the decay of stone-built heritage, including his PhD on the impact of complex stress histories (sequences of lime rendering, fire, frost and salt weathering) on the decay of historic stone structures and the ensuing conservation implications. Through this project, he seeks to understand the greening and deterioration of sandstone walls under wet conditions. In 2011 he received a Queen's Impact Award (sponsored by EPSRC), for the purpose of communicating this research to a wider audience, particularly conservation practitioners.
