My principal research areas use geochemical information, particularly stable isotopes, in the reconstruction of environmental and climatic conditions, and the local cycling of elements that impact society (such as carbon, nutrient and contaminant metals). My research covers long temporal scales including modern environments, the recent geological past (Quaternary) and deeper geological time. My research has recently focused on three themes: 1. Stable isotope records in terrestrial calcium carbonate deposits (tufas, stromatolites, cave deposits etc.) as ways of reconstructing, validating and dating terrestrial palaeoclimatic events over the last 200,000 years. I am currently working on suitable sites in the UK, Greece, Turkey, Iran, and India. 2. Geochemistry of carbonate sediments as indicators of global sea level and wider palaeoenvironmental change in the Quaternary Oceans. With Prof. M. Leeder and Dr P. Rowe (both UEA), we are unravelling the sedimentological record of sea level change during the last interglacial, principally in the uplifting coastlines of central Greece.
