Laminated sediments from a sediment core taken from the Nigavan wetland, Armenia. Fossilized pollen from the same sediment core representing common steppe plant taxa. Macro-charcoal remains from the same sediment core used to reconstruct the landscape fire regime.
Research Statement:
I am a transdisciplinary environmental archaeologist, paleoecologist, and paleoclimatologist with extensive experience analyzing lake and archaeological sediment archives across the Holocene in the arid and semi-arid environments of the Caucasus and Central Asia. My research integrates methods and theory across archaeology, paleoecology, paleoclimatology, archaeobotany, and statistics. I center this approach on utilizing the past to help understand how human communities have and will adapt to past, present, and future climate and ecological change.
I focus on four unique but entangled aspects of environmental transitions: human-driven agro-pastoral change, climate, landscape fire, and vegetation change. I use a multi-proxy methodological approach, which includes pollen, lipid molecular biomarkers (GDGTs), machine and statical learning, non-pollen polymorphs, macro-charcoal, and XRF core scanning, on lake sediment cores. Combined, these data provided crucial information about how humans have interacted with their regional vegetation, the landscape fire regime, the impacts of agro-pastoralism, and the history of climate change. My research has been funded by fellowships and grants from the National Science Foundation (GRFP), the French Embassy in the United States (Chateaubriand), and Cornell's Atkinson Center for Sustainability.
