Wissenschaftliches Profil
(No German text available)

I have a scientific background in Earth Sciences and Geology. During my studies I gathered solid experience in different fields, such as Paleontology, Sedimentology, Stratigraphy. In my research career I have conducted studies within a series of different scientific disciplines, including Marine Ecology, Paleoceanography, Paleoclimatology and Geochemistry. Within my PhD, I developed an innovative technique using coccolithophore assemblages to calculate paleotemperatures on sedimentary sequences from the Pacific Ocean. Results obtained from my work were presented in different national and international meetings where they were awarded on two separate occasions and published in relevant peer reviewed journals. During my Postdoc research I have got a vast expertise in extant coccolithophores and calcareous nannofossils at high latitudes. I also gained experience as a biostratigrapher during long research cruises, such as IODP Expedition 346: Asian Monsoon.
