Ianto Wain has over 20 years' experience as a professional archaeologist and is a Member of the Chartered Institute for Archaeologists (MCIfA). He has extensive experience in heritage management and environmental impact assessment (EIA). He has completed numerous EIAs of large-scale infrastructure, housing, energy, commercial and linear projects, including West Coast Main Line, HS1, South-West Oxfordshire Reservoir, Merthyr Village, Exeter Science Park and road schemes including M1, M20, M25, M40 and A11. He also has Public Inquiry Expert Witness experience.

In addition to his EIA specialism he has a strong track record in historic landscape research and analysis, urban surveys, characterisation surveys and the preparation of management proposals for archaeological monuments. He has carried out condition and management surveys for a wide range of archaeological monuments including Stonehenge, Avebury World Heritage site and Maiden Castle. He managed and had significant input into the Oxford Archaeological Database (a major review of the archaeology of the historic city of Oxford) and has recently completed the management of a number of large-scale strategic policy reviews for English Heritage, a review of the use of Historic Landscape Characterisation in the Irish Republic for the Heritage Council of Ireland, and a review of potential cumulative impacts for the construction of offshore windfarms.

A graduate of the University of Newcastle-upon-Tyne, where he obtained a BA (Hons) in archaeology, John has worked as a professional archaeologist for nearly 30 years, becoming a Member of the Chartered Institute for Archaeologists (MCIfA) in 1987. A highly experienced fieldwork director and post-excavation researcher, John spent much of his early career working in historic urban environments, where he gained considerable expertise in the excavation of highly complex archaeology, including internationally significant waterlogged deposits.

John is vastly experienced in the excavation, recording and interpretation of multi-period archaeological remains, though his principal research interests lie in the archaeology of the Roman army and the development of urbanism in Britain. Since joining OA North in 2001, he has established a reputation as a leading expert on the Roman period in northern England, and has developed a strong track record of post-excavation analysis and publication. John has authored a wide range of archaeological reports, including substantial monographs presenting the results of large-scale urban excavations he directed at Winchester and Carlisle.
