Liliana Siekacz

Visiting Scholar From Nicolaus Copernicus University in Toruń, Poland

Liliana is currently PhD student at Nicolaus Copernicus University in Toruń (Poland). She conducts her project within Academia Copernicana Interdisciplinary Doctoral School between the disciplines of Earth and environmential sciences (advisor Dr Charlotte Pearson, University of Arizona) and biological sciences (advisor Dr Marcin Koprowski, Nicolaus Copernicus University). In her research 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.

She 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.
