Research Summary

Isotope Geochemistry, Organic Geochemistry, Social Geochemistry

Research Statement

I focus on investigating the connections and interactions between the geological and biological sciences through the use of stable isotope ratios and elemental profiles of organic materials and inorganic phases. My research seeks to address questions of societal importance using geochemical tools and to translate these finding into civil, economic, and environmental improvements. My primary academic strengths are in the fields of isotope geochemistry, organic geochemistry, isotope forensics, paleoclimatology, and paleoecology.
