Paula Reimer

BSc Msc PhD MRIA

Prof. Paula J. Reimer is the Director of the 14CHRONO Centre for Climate, the Environment, and Chronology in the School of Natural and Built Environment at Queen’s University Belfast. She leads the international radiocarbon calibration working group (IntCal) and is actively involved in research on carbon reservoir changes and carbon sources in sediment and soils. Paula is also interested in the use of stable isotopes in palaeodietary studies as a way of understanding radiocarbon reservoir effects on the accuracy of dating humans and animals subsisting on marine or freshwater resources.

Evelyn Keaveney

BA MSc PhD MRSB

Dr Evelyn Keaveney is a Research Fellow at in the School of Natural and Built Environment. She completed her PhD investigating freshwater reservoir offsets in 2010 and since then has been carrying out original research involving the novel use of radiocarbon as a biomarker to analyse carbon pathways in freshwater lakes. She is interested in carbon cycles, climate change and the impact of human activity on lakes and rivers. She has recently been instrumental in the construction of a Ramped Pyrolysis Combustion facility in the 14CHRONO Centre and will be using it to partition carbon sources and refine the chronologies of bulk sediment/soil/peat samples and sequences.
