The main part of my PhD research (Swansea) involved analysis and interpretation of annually resolved stable isotope ratios from seven individual bristlecone pine trees cellulose covering the last millennium. Following my PhD .

I worked as an Isotope dendrochronology research technician on the EU funded ‘Millennium’ project looking at European climate of the last 1000 years. In particular I was involved in developing a Slovenian larch ring width chronology and a 550 year stable isotope chronology from the same trees.

I have fourteen years work experience of field and laboratory archaeology, including experience of environmental sampling techniques, and have undertaken paid work involving various aspects of dendrochronology/archaeological wood (including dating living trees, remnant and waterlogged wood, historic buildings).

In my present role as research assistant for the departments archaeological consultancy (UWLAS) I am involved in dendrochronological dating of wood (living trees, buildings and waterlogged wood), analysis of archaeological wood assemblages, geophysical survey, field sampling for environmental archaeology, preparation of sediment samples for pollen analysis, sieving, selecting samples for 14C dating and data analysis.

As part time laboratory technician I am responsible for the day to day running of an active multi disciplinary environmental archaeology laboratory.
