Professor of Quaternary Palaeoenvironments at the Department of Geography, University of Cambridge, United Kingdom. His main interest is in Pleistocene and Neogene Geology, sedimentation and the construction of stratigraphy using appropriate litho-, bio- and chronostratigraphical methods to establish the changing palaeogeography and palaeoenvironment for any particular area. As a geologist, Phil is principally involved with the Quaternary and late Neogene, including its palaeogeographical and palaeoenvironmental evolution, with interests spanning the terrestrial (glacial, fluvial and lacustrine) and shallow marine realms. His studies have mainly focused on Europe, but he has conducted research in North America, the Mediterranean, South Asia and South America. His approach is based on the rigorous stratigraphy of sedimentary sequences, using a wide range of techniques, and its purpose is to develop detailed frameworks which have provided the basis for palaeoenvironmental, palaeoecological and palaeogeographical reconstructions.
