Research interests
My current research interests encompass the Baltic sea coast evolution and interactions between the sea level fluctuations, local climate change, and microorganisms responding to it on multiple temporal and spatial scales. I use interdisciplinary field- and laboratory-based approaches including the analysis of sediment cores, processing and interpretation of radiocarbon dating data; and implementation of high-resolution micropaleontological and geochemical analyses. Geography of my current project span the southeastern Baltic Sea coast.
Annotation of the dissertation
The aim of my current research work: reconstruction of the south-eastern Baltic Sea coast development history during the Late Glacial and Holocene on basis of multiproxy studies.
The main research objectives are:
1. To determine the diatom compositional changes in key Baltic Sea coast sediment sections;
2. To characterize the stages of the Baltic Sea development according to the diatom composition;
3. To correlate the diatom analysis data with palaeobotanical, isotopic and lithological etc. investigation data;
4. To compare the identified palaeoenvironmental variations with global climate events and patterns of the neighboring areas.
