My expertise lies in stable isotope-based paleoenvironment reconstruction from archaeological sites. I utilize multiple bulk isotopes, plant-wax biomarkers, and molecular isotope analyses (CSIA) as proxies to comprehend past human-environment interactions. I am also involved in method development for biomarker compounds used to understand the past diet and identify plants from various materials in archaeological contexts. Additionally, I am researching macro-charcoal and polycyclic aromatic hydrocarbons (PAHs) analyses to gain insights into the past use of fire by humans.
