Olga is a micropalentologist. She studies ostracoda and Foraminifera, addressing research questions of tracing anthropogenic impacts, paleoecology, and geoarchaeology. To achieve this, she relies on (paleo)ecological analyses, including multivariate analysis, morphological assessments, and shell chemistry methods, all supported by reliable taxonomy and geochemical data.

For her PhD, Olga analyzed recent microfaunas taken from four different aquatic systems in Ghana and South Africa to evaluate their potential as indicators of anthropogenic impacts. She combined results from ostracod and foraminifer analysis with geochemical and sedimentological data.

In her current transitional postdoctoral phase, Olga is deepening her focus into paleoenvironmental work with microfossils. She is part of an International Continental Scientific Drilling Program (ICDP) in Nam Co, one of the largest and deepest lakes on the Tibetan Plateau. Olga is also investigating archaeobotanical remains in the DAE group.
