About this position

PhD student in Environmental Science focusing on chemical persistence in the hadal zone
Stockholm University

Are you curious about the deepest parts of our planet and how they interact with human-made chemicals? The Department of Environmental Science are looking for a PhD student to join the Contaminant Chemistry Unit in the project:

“Small but efficient – can hadal sediment microbes degrade persistent chemicals? (Hadal-Degrade)”

In this project, you will investigate contaminants in sediments from the world’s deepest ocean trenches (6–11 km below the surface) using state-of-the-art mass spectrometry. You will explore how microbial communities in hadal zones may break down pollutants and contribute to fundamental knowledge about contaminant cycling—and potentially to sustainable bioremediation solutions on Earth.

?? What the Department of Environmental Science is looking for

Applicants should have a strong background in natural sciences (chemistry, biology, earth sciences, physics, or meteorology). Experience with chromatography, high-resolution mass spectrometry, and trace analysis of environmental contaminants is a merit.

Employment: 4-year, full-time PhD position
?? Stockholm University
?? Supervisor: Professor Anna Sobek
?? Apply via Stockholm University’s recruitment system. Deadline and full instructions below ?? https://lnkd.in/d56Qs9T6

Deadline: 3 November 2025
