Dr MELANIE HAYES is an architectural historian, specialising in eighteenth-century architectural and craft history, with a specific interest in the transmission, reception and production of architecture and craftsmanship in Britain and Ireland. Her recent research has explored the collaborative nature of work practice within the eighteenth-century building industry, contributing to a burgeoning new direction in the study of architectural labour and agency in the period. She has previously taught early-modern architectural history at Trinity College Dublin, and has written, and spoken widely on these topics. She is author of The Best Address in Town: Henrietta Street Dublin and its first residents, 1720–80 (Four Courts Press, 2020) and co-editor of Enriching Architecture: Craft and its conservation in Anglo-Irish building production, 1660–1760, edited by Christine Casey and Melanie Hayes (UCL Press, 2023), and Between Design and Making: Architecture and craftsmanship1630–1760, edited by Andrew Tierney and Melanie Hayes (UCL Press, 2024).

Dr NELE LÜTTMANN is an architectural historian and research assistant at Trinity College Dublin, where she earned her PhD in History of Art and Architecture. Her dissertation examines contributions of German draughtsmen in early eighteenth-century Britain and Ireland, emphasising the evolution of drawing practices and the collaborative dynamics within architectural offices. Fluent in both German and English, Nele possesses extensive expertise in archival research and academic editing, which she will leverage to enhance the European historiographical aspects of STONE-WORK while assisting the Principal Investigator. Her key responsibilities include analysing historical resources related to stone sourcing, trade networks, and the orchestration of stonework practices, contributing to a comprehensive understanding of architectural history in Britain and Ireland.

MARY (MÁIRE) NEVIN is a Doctoral Researcher on the STONE-WORK project at Trinity College Dublin. She holds a BA in Art History & Archaeology and an MA in Art History, Collections and Curating from University College Dublin. Mary's professional experience includes roles at several Irish cultural institutions, such as the National Gallery of Ireland and Butler Gallery. Most recently, she worked as an Assistant Curator at the National Museum of Ireland – Archaeology, contributing to an exhibition of early medieval Insular art. Mary's academic interests encompass the architecture of classical antiquity and European classicism/neoclassicism. Her PhD research examines the eighteenth-century chimneypiece industry in Britain and Ireland, exploring the sequence of agents, actions, and processes involved in stone production during this period. This research aims to enhance understanding of historical stone-working practices and their cultural context, building upon Mary's professional and academic background.

Dr RUTH SIDDALL is a geologist who has worked on Earth materials in cultural heritage for over 30 years, primarily studying stone, pigments and ceramic materials. She has worked with a wide range of materials from Classical and Egyptian antiquity and on construction materials in western Medieval and Victorian architecture.

He has published over 300 research papers and books in other fields, including the history and philosophy of geology, palaeontology, and the use of building materials in Ireland. His research output has informed local and national government policy on landscape protection and heritage issues. He was a co-PI on the innovative cross-disciplinary project Making Victorian Dublin being carried out with colleagues in the Department of the History of Art and Architecture in Trinity. This project focused on the extractive industries and building trades, and craftsmen who worked on the Museum Building and elsewhere, in the middle decades of the 1800s. He is the co-editor of The Museum Building of Trinity College Dublin: a model of Victorian Craftsmanship(Four Courts Press, 2019). His current project STONEBUILT IRELAND funded by the OPW and Geological Survey Ireland examines the use of dimension and decorative stone in Ireland through many building phases. His books include The Decorative and Building Stones of Dublin: a walking guide (2025) co-authored with Dr Louise Caulfield, The Chronologers' Quest: episodes in the search for the age of the Earth(Cambridge, 2006) and Introducing Palaeontology: a guide to ancient life(Dunedin Academic Press, 2010; 2nd edition 2019).
