Jacqueline Stefels

Dr. Jacqueline Stefels is a Senior Scientist and Lecturer in Marine Microbiology at the University of Groningen's Faculty of Science and Engineering. Her research examines the ecophysiology of marine microalgae, focusing on biogeochemical cycles of climate-relevant gases like dimethylsulfide (DMS) in polar environments.

Research interests center on marine phytoplankton interactions with climate systems, including polar sea ice ecosystems, carbon-sulfur cycling, and algal responses to environmental stressors. Her work combines field expeditions (e.g., MOSAiC Arctic mission) with laboratory analysis of algal physiology and gas exchange processes.

Recent publications explore carbon fixation pathways in phytoplankton, Arctic ecosystem dynamics, and Antarctic sea ice nutrient cycles, reflecting interdisciplinary approaches to understanding climate-biosphere interactions.
