A geologist with expertise in petrographic analysis of natural stone, concrete and historic mortars, using optical and electron microscopy. Currently working on all of these, on the physical properties of replacement mortars for conservation and developing interdisciplinary collaborations concerned with heritage science, materials and climate change.
Construction materials performance and analysis- cement, concrete, stone, mortar especially in historic buildings.
Provenance recognition in historic construction materials.
Interdisciplinarity in cultural heritage, climate change impacts on buildings and sites.
Current Research Student supervision:
Marta Zurakowska: Current mechanisms and future patterns of stone decay in cleaned sandstone and granite buildings
Dorn Carran: Understanding traditional masonry mortars to improve the compatibility of mortar repair
Torsten Howind: Micro-mechanical properties of innovative cement-based materials students
Present: Reader, University of Western Scotland
