  • Wood and charcoal identifications
  • Wood analysis and reporting on worked wood and wooden artefacts
  • General advice for wood and charcoal sampling strategies on archaeological excavations to produce the most informative data set for further analysis and later publications
  • Pollen and microfossil studies including macroscopic charcoal in relation to vegetation reconstructions and human dynamics.


I graduated from University College Dublin in 1991 with a BA Honours degree in Celtic archaeology. After working on various wetland excavations with the Irish Archaeological Wetland Unit I became interested in wood identifications and wood use as well as research investigations towards woodland reconstructions and woodland management. In 1994 I completed an MA in archaeological methods and practices from University College Cork. My thesis was on ‘’The Analysis of Two Wooden Assemblages from Corlea bog Co. Longford and King John's Castle Co. Limerick." Since 1994 I have worked on various excavations and research projects as well as completing many environmental reports associated with the analysis of charcoal and wood as well as wooden artefacts from archaeological excavations.

I was awarded a PhD in 2012 on ‘Quantifying woodland resource usage in the Irish midlands using archaeological and palaeoecological techniques’ under the supervision of Professor Fraser Mitchell at the Botany Department, Trinity College, Dublin.

I have just completed a comprehensive document with Dr. Meriel Mc Clatchie on ‘Guidelines for the retrieval, analysis and reporting of plant macro-remains, wood and charcoal from archaeological deposits, and the use and applicability of pollen analysis for the National Roads Authority.

I am currently part of the environmental research team on the National Museum of Ireland’s ‘Irish Bog Body Project’ co-ordinating as well as undertaking pollen, wood, peat plant macro studies and charcoal research associated with Cashel man, Co. Laois.
