Liliana Siekacz

Graduate Student

Liliana graduated her master degree in Geography at Adam Mickiewicz University in Poznań with a thesis entitled: “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, climatic changes and volcanic eruptions. During her master studies she participated in three research expeditions to Adam Mickiewicz University Polar Station in Svalbard, spending more than half a year there in total. 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). In particular she will focus on blue rings (unlignified tree-ring structures) and to explore their connection with climatic changes at a cellular level and over a multi-millennial time period.
