I have co-ordinated and led two major EU research consortia (SHELF and HOLSMEER), was a senior member of the 40-partner EU MILLENNIUM project (European Climate of the Last Millennium), and have held eleven NERC research grants. Much of my research is based at sea and I have served as Chief Scientist on 10 research cruises. I was President of the Quaternary Research Association (2008-2011) and Chair of the NERC Radiocarbon Facility Steering Committee (2007-2011). I was Editor of the Journal of Quaternary Science (2000-2004) and was awarded a Royal Society-Leverhulme Trust Senior Research Fellowship in 2008-2009. I was elected a Fellow of the Learned Society of Wales in 2014 and was Director of the Climate Change Consortium of Wales between 2011 and 2016.
