About this opportunity

Opportunity Overview

The Institute of Geological Sciences, Polish Academy of Sciences, in Warsaw is seeking a Post-doc researcher for a project focused on understanding the patterns of variability of stable isotopes in terrestrial temperate ecosystems. The successful candidate will be part of a research team investigating the isotopic variability of amino acids in modern and fossil plant and animal tissues. The project aims to better interpret the isotope flux in fossil assemblages, with a focus on bone collagen. The research will be conducted at the IGS PAS Research Centre in Warsaw, with some foreign trips required for training and conferences. The Post-doc position is available for a highly motivated and experienced researcher with a doctoral degree in Earth science, environmental science, chemistry, biology, or related disciplines. The ideal candidate will have experience in biochemical and geochemical analyses, laboratory work with chemical compounds, and stable isotope analysis. The researcher will be responsible for conducting scientific research, laboratory work, data analysis, and preparation of articles for scientific journals. The research project will involve laboratory analyses, including EA-IRMS, GC-FID/MS, and GC-C-IRMS of stable carbon and nitrogen isotope composition. The researcher will also be responsible for refining the GC-C-IRMS method, including measurement techniques and derivatisation methods. The project's ultimate goal is to use the patterns of modern isotopic variability to better interpret the isotope flux in fossil assemblages.
