Phil's 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. Within this general field the following topics hold particular interest: Glacial, periglacial and interglacial stratigraphy, sedimentation and structure, including Baltic Sea history. The main regions are Europe and North America. Fluvial sedimentation and drainage evolution. The history of the River Thames, its tributaries and lowland Europe in general. Shallow marine and coastal sedimentation in NW Europe and southern Asia. Palynology of Pleistocene and Neogene deposits in both interglacial and glacial periods. Palaeoenvironmental reconstruction combining both floral and faunal fossils and sedimentary evidence. Miocene sedimentation in Turkey. Stratigraphical concepts and application. Palaeogeographical information.
