Doctoral Researcher (PhD) in Low-temperature Silicon Isotope Geochemistry (all genders welcome)

An der Georg-August-Universität Göttingen Stiftung Öffentlichen Rechts – Göttinger Zentrum für Geowissenschaften -Abt.7-Sedimentologie-Umweltgeologie ist ab dem 01.03.2027 eine Stelle alsDoctoral Researcher (PhD) in Low-temperature Silicon Isotope Geochemistry (all genders welcome)- Entgeltgruppe 13 TV-L - in Teilzeit mit 75% der regelmäßigen wöchentlichen Arbeitszeit zu besetzen. Die Stelle ist befristet bis 28.02.2030.We invite applications for a doctoral researcher position in low-temperature stable isotope geochemistry, with a particular focus on silicon (Si) isotope ratios and germanium-to-silicon (Ge/Si) ratios in siliceous materials. The project combines laboratory experiments, analytical method development, and geochemical investigations of natural samples to investigate secular changes of silicon isotope ratios in seawater. The position is intended to support early-career researchers, and is based on a fixed-term contract for three years beginning March, 2027 or as soon as possible thereafter. Payment will be in accordance with the German collective agreement for public employees (TV-L E13, 75% of a full position, 29.85 h/week). The successful candidate will conduct independent doctoral research within a collaborative research environment and develop expertise in isotope geochemistry, advanced analytical instrumentation, and experimental and analytical method development. Your Responsibilities · Prepare and chemically process geological and environmental samples, including rocks, sediments, and water samples, for silicon isotope analysis · Automate laboratory procedures for chemical sample purification · Conduct laboratory experiments and analytical measurements, including data quality assessment and interpretation of geochemical results · Contribute to the design and scientific development of the research project · Prepare manuscripts for publication in international peer-reviewed journals and present research findings at scientific conferences Your Qualifications · A Master&39;s degree in geosciences, geochemistry, chemistry, or a closely related discipline, with a strong academic record and eligibility for admission to a doctoral programme · A strong interest in stable isotope geochemistry and Earth surface processes · Practical laboratory experience, a systematic and careful approach to experimental work, and an interest in analytical method development and optimization · Very good written and spoken English · You can work independently, solve experimental problems, and collaborate effectively within an interdisciplinary research environment · Previous experience with mass spectrometry, elemental analysis, or isotope ratio measurements is desirable but not essential What We Offer · The opportunity to pursue a doctoral degree in a research group specializing in isotope geochemistry · Comprehensive training in advanced analytical techniques and instrumentation, including MC-ICP-MS, ICP-MS, and ICP-OES · Opportunities for independent scientific research, interdisciplinary collaboration, and participation in international scientific conferences · A collegial and intellectually stimulating research environment that encourages open scientific exchange, innovative ideas, and independent thinking · Flexible working hours and access to university facilities, including university sports programmes Please submit your application as a single PDF file via the University of Göttingen&39;s online application portal by 3 January 2027. Applications should include a cover letter outlining your research interests and motivation, a curriculum vitae, academic transcripts and degree certificates.
