Isabel Fendley

Isabel Fendley is an Assistant Research Professor in the Department of Geosciences at Pennsylvania State University's College of Earth and Mineral Sciences. Her research focuses on volcano/climate interactions, paleoclimate reconstruction, and environmental changes linked to mass extinctions.

• Affiliation: Department of Geosciences, College of Earth and Mineral Sciences, Pennsylvania State University
• Research Themes: Large igneous province (LIP) eruptions, geochemical proxy development (mercury/sulfur isotopes), paleoenvironmental responses to volcanic gas emissions, and modern volcanic-climate interactions

She investigates both ancient geological events associated with mass extinctions and contemporary volcanic systems, analyzing sedimentary and igneous rock records to quantify volcanic gas emissions (CO2, sulfur, mercury) and their climatic/environmental impacts across timescales.

Her work connects Earth history with present-day challenges, examining hydrothermal systems and biogeochemical mercury cycling in modern environments.
