Liliana graduated her master degree in Geography at Adam Mickiewicz University in Poznań with the thesis: “Annual growth rings of dwarf shrub Salix polaris subjected to active layer detachment and solifluction processes in polar climate conditions (Ebbadalen, Spitsbergen)”. Her research interests are focused on dendrochronology, especially on the information about past environmental changes encoded in tree rings related to geomorphic processes and climatic changes.
During her master studies, she participated in three research expeditions to Adam Mickiewicz University Polar Station in Svalbard where she collected material for her master thesis spending there more than half a year in total. She also spent a semester at Eötvös Loránd University in Budapest on Erasmus exchange.
In 2018 she has spent 2 months on an internship at the Laboratory of Tree Rings Research of the University of Arizona establishing cooperation with LTRR scientists dr Charlotte Pearson and dr Matthew Salzer and starting to work on her current doctoral project.
In her doctoral project, she’s working to uncover information encoded in the microanatomical structure of radial increments of Great Basin bristlecone pine (Pinus longaeva) especially the understanding of the of blue rings phenomenon (unlignified ring structures) and the information about past climatic fluctuations induced by climatically effective volcanic eruptions.
