Ingrid Obernosterer received her PhD in Biological Oceanography at the University of Groningen (The Netherlands) in 2000. She was awarded the Schroedinger Fellowship (Austrian Science Foundation) and a Marie Curie Fellowhsip by the European Community to support her Post Doctoral research at the University of South Carolina (USA) and the Laboratoire d’Oceanographie Biologique (Banyuls, France).

She is presently a CNRS Research Scientist at the Laboratoire d’Océanographie Microbienne (Banyuls, France). I. Obernosterer has expertise in marine biogeochemistry, aquatic microbial ecology and marine organic matter cycling. Her research is centered on key issues on the bioavailability and transformation of different sources of dissolved organic carbon by the microbial community, and the metabolic balance of the ocean. Due to her participation to the international project KEOPS, she has experience with the particularities of the Southern Ocean system.
