Stephen’s research focuses on Biogeography, specifically the use of dendrochronology (tree-rings) as a means of understanding and contextualising environmental change. Tree-rings are one of the most valuable sources of proxy data due to the high resolution at which they record and reflect environmental variables. Stephen’s research has examined the impact of low-latitude and Icelandic volcanic eruptions on tree growth and climate. He has published on the benefits associated with using Taxus baccata (yew) in tree-ring research, the impact of volcanic eruptions on temperature regimes, and the positive impact of Iceland volcanic eruptions on tree-growth in Ireland. He is currently involved in an exploratory study investigating the use of tree-rings in reconstructing historical pollution patterns. Stephen aims to develop dendrochronological research to investigate the long-term dynamics of one of Fiji’s most valuable assets – the rainforests.
