Tanja Stratmann

Dr. Tanja Stratmann is a Postdoctoral Researcher at Utrecht University's Department of Earth Sciences within the Faculty of Geosciences since July 2025, with prior affiliations at NIOZ Royal Netherlands Institute for Sea Research (2022-2025), Max Planck Institute for Marine Microbiology (2019-2022), and Ghent University (2018-2019).

• PhD in Marine Sciences (2018) from NIOZ/Ghent University
• MSc in Statistical Data Analysis (2019) from Ghent University
• MSc in Biology (2014) from Aarhus University

Her research focuses on extreme marine environments, particularly deep-sea ecosystems and polar regions. Key areas include:

• Environmental impacts of deep-sea mining
• Benthic food web dynamics using isotopic tracers
• Megafaunal roles in carbon/nitrogen cycling
• Dissolved organic matter cycling in Arctic systems

Recent work analyzes 13C, 15N, 2H tracers in sponge feeding studies (2025) and Clarion-Clipperton zone food web integrity (2023). Her databases (BenBioDen, ProkaBioDen) support global marine research.

Scientific Recognition:

• Veni Laureate (2022)
• Open Science XS Grant (2022)
• Rubicon Research Fellowship (2019-2022)
