PhD position in sedimentary and petroleum Geochemistry

Organic-rich sedimentary rocks provide valuable geochemical data to understand the changing conditions of the oceans, continents, atmosphere, and life throughout geologic history. When subjected to the right conditions, part of the organic matter in these rocks is converted into economically viable hydrocarbons (e.g., bitumen, oil, gas). The link between hydrocarbon deposits and their source rocks is usually established through organic biomarkers. This approach, however, has certain geologic limitations.

This PhD project will explore novel inorganic geochemical tools for linking organic-rich source rocks and their petroleum products. The successful applicant will have Master's degree in geosciences or related field like environmental sciences, chemistry or material sciences. We seek a responsible and enthusiastic student with good oral and written English language skills. Laboratory experience is desirable.

The PhD candidate will summarize published data and collect new samples during short field work campaigns. Sample preparation, acid digestion, and ICP-MS analyses of trace metals will be conducted in the facilities at the GI-BAS and the Department of Chemistry at Sofia University "St. Kliment Ohridski. The student will travel internationally to participate in stable isotope analyses of selected metals at partnering geochemical laboratories and to present research results at leading conferences. Results will be published in peer-reviewed international scientific journals.

This is a fixed-term contract for three years with a preferred starting date in October 2022. Remuneration will be for 2000 BGN (~1130 USD) per month for a full time (40 h/week) position, including employer's insurances, pension deductions, etc.

How to apply: Prepare your application as a single PDF including: (1) motivation letter highlighting relevant geological and analytical experience; (2) a CV and copies of diplomas and certificates; (3) a short summary of your master thesis; (4) the names and addresses of at least two referees. Submit your file at The initial review of applications will begin on May 13, 2022; the position will remain open until a suitable candidate is selected.
