Research Interests

  • The use of chemical and isotopic techniques to determine the relationship of climate and flora to soil properties.

Recent work with archaeological applications includes:

  • The use of stable C and O isotope ratios in soil carbonates to evaluate paleoclimates.
  • C isotope ratios of opal phytoliths as an indicator of vegetation change.
  • C and O isotope ratios of hackberry (Celtis sp.) endocarps as an indicator of paleoclimate.
  • Radiocarbon dating of soil carbonates as an indicator of landform age.
  • Geochemical analysis of residues on stone tools as method of determining food processing practices.

Collaborations/associations with ARF members have been made with the late Professor George Dales on the Harappa excavations, and with Desmond Clark on stone tool surface residues.
