Research interests and activities

  • Continental-scale environmental responses to rapid climate variability (including Dansgaard-Oeschger and Heinrich Events) through the synthesis of European high-resolution pollen data for the last glacial period
  • Long-term and millennial-scale environmental changes in the Mediterranean region, during the last and preceding glacial-interglacial cycles, with foci on the western Mediterranean (Iberian Peninsula, northwestern Africa and the Atlantic façade) and eastern Mediterranean (northern Aegean) using high-resolution pollen analysis in the context of multi-proxy investigations of marine and terrestrial sediment archives
  • Holocene palaeoenvironmental change in response to climatic variability, human impact and sea-level change, with foci on the Iberian peninsula and northern Adriatic, using palynology, anthracology (macroscopic charcoal analysis), and sedimentology of estuarine, alluvial and cave sedimentary deposits.
  • Environmental change in the Middle and High Atlas, Morocco, including vegetation history, timing and extent of glacier advances, human-environment interactions and human exploitation of the mountain environments.
