Research Interests

Science-based archaeology: specifically palaeoenvironmental reconstruction focusing on environmental change and its effects on hominid physical and cultural evolution; palaeoenvironmental and palaeoecological reconstructions of archaeological sites based on sedimentology and stable isotopic indicators.

Current Projects

  • Palaeoenvironmental change and hominid mobility in the Thar Desert and Andhra Pradesh, India
  • Oldowan hominid behavior and ecology at Kanjera South, Kenya
  • Palaeoenvironments, landscape evolution and hominid land use patterns at Olorgesailie, Kenya
  • Pliocene environments and hominid land use at Laetoli, Tanzania
  • A long-term record of environmental change in Bubing Basin, south China
  • Chinese Human Evoutional Research Project
  • Chronological and environment setting for the Aterian Industry, eastern Morocco

Research Grants Awarded

  • 2007 Taxon-free methods for palaeontological methods for reconstructing environmental change (Co-investigator) Leverhulme Trust application
  • 2007 The Toba super-eruption and its impact on human populations and ecosystems (Co-investigator) Leverhulme Trust award
