The University of Lausanne (UNIL) is offering a 5-year PhD position in the Institute of Earth Surface Dynamics (IDYST), focusing on soil biogeochemistry in proglacial margins. The successful candidate will join the pedology group and work on quantifying chemical weathering fluxes in environments exposed by glacier retreat. This research is crucial for understanding the carbon cycle and feedbacks between glacier retreat and atmospheric CO2, as newly exposed sediments undergo active pedogenesis and chemical weathering. The project involves fieldwork in remote alpine locations, soil and water sampling, wet chemical laboratory analyses, and the development of quantitative frameworks to estimate weathering fluxes. The candidate will also contribute to teaching soil courses at the Bachelor and Master's level, especially in the Masters of Biogeosciences, and participate in research and outreach initiatives such as the Swiss-Soil resource. Applicants should have a Master's degree in soil science, biogeochemistry, geology, or earth science, with a solid background in pedology, mineralogy, and geochemistry. Experience in weathering studies is advantageous but not required. Candidates must be able to conduct fieldwork in challenging alpine environments and have an interest in laboratory work. Statistical and modelling skills, or a willingness to learn them, are expected. Proficiency in English and a working knowledge of French are required, with French classes available to help reach the necessary level within a year of hiring. The position offers a renewable contract (1 year, renewable twice for 2 years each, up to 5 years total) at 80% activity rate, with a salary according to Swiss university standards. The academic environment at UNIL is multicultural, diverse, and dynamic, with numerous opportunities for professional and scientific growth, including doctoral courses, networking, and career counselling. The Faculty of Geosciences and Environment (FGSE) provides a supportive community of doctoral students, organized seminars, and social activities. To apply, candidates must submit a motivation letter, CV, degree certificates and transcripts, an electronic version of a research output (such as a scientific publication or MSc thesis), and contact information for two professional references. Applications must be submitted through the official website by February 15, 2026. For further information, applicants can contact Dr. Stéphanie Grand at [email protected]. UNIL is committed to equality, diversity, and inclusion, providing a respectful environment conducive to personal development and supporting early career researchers.
