Paula Andrea Vignoni

Paula Andrea Vignoni is a Researcher at the German Research Centre for Geosciences (GFZ) within the Geosystems School, specifically in the Geomorphology Department. Her work focuses on climatic and environmental changes in high-altitude lake systems across the Andes and Antarctica, with expertise in geochemistry, isotopic analysis, and paleoenvironmental reconstruction. Vignoni holds a PhD from Universität Potsdam (2024), focusing on lake sediments in the Southern Puna Plateau as climatic archives. She has contributed significantly to understanding hypersaline Andean lake geochemistry, radiocarbon reservoir effects, and Antarctic microbial ecosystems through fieldwork and interdisciplinary collaboration. Her research bridges geomorphological processes, climatic dynamics, and biogeochemical cycles in extreme environments.

Education: PhD in Geosciences (2024), Universität Potsdam. Key research areas include paleolimnology, isotope geochemistry, and environmental geoscience.

Her work emphasizes the Puna Plateau and Antarctic regions, with publications analyzing lake sediments, carbonate composition, and microbial diversity. She maintains active collaborative networks in South America and Antarctica, contributing to global climate change studies through high-altitude environmental archives.
