I am driven by a great curiosity about processes of change in the natural world, whether anthropogenic, or driven by natural cycles. My research uses geochemical and physical analyses of sedimentary records to discern climatic and environmental change at various temporal and regional scales. My current project explores the glacial history of the Eastern Sierras in California using the sedimentary record of June Lake, CA. My prior work as a Lecturer in Geology at Concord University was perhaps the greatest driving factor in my decision to pursue a PhD. As such, after completing my dissertation at UK, I hope to earn a faculty position that allows me to both teach and mentor undergraduate research.

My research uses stable isotope analysis as a tool to explore the connection between  shark ecology and environment with shark teeth isotopic composition. Current projects include: (1) Biological parameters based on organic carbon and nitrogen isotopic values to interpret modern shark ecology (based on teeth taken from a captive feeding experiment), and (2) Eocene high-latitude temperature gradients over time and space based on oxygen isotope values of fossil shark teeth and bivalves from La Meseta formation in Seymour Island, Antarctica.

As an undergraduate at UC Santa Cruz, I joined Sora as a student aid for her PhD dissertation project. She was a superb role model who encouraged her team to formulate new ideas and think outside of the box. Working with her was the boost I needed in deciding to work intimately with animals and apply for veterinary school. A decade later, I am lucky to have her as a friend and sounding board.
