I am a palaeoclimatologist with a special interest in micropalaeontology, using microfossils, such as dinoflagellates and pollen, to reconstruct past oceanographic, terrestrial and climatic changes. More recently, I have expanded my research into vegetation reconstructions using pollen in speleothems (e.g. stalagmites). I am particularly interested in time periods in Earth history that were warmer than present in order to gain insights into environmental changes under continued future warming.
