Cojean, Adeline

Postdoctoral Researcher



As an educated chemical oceanographer and biogeochemist, I am interested in investigating the interplay between biogeochemical cycles (N, Fe, Mn, S, C) and associated microbial communities in aquatic environments. My current research focuses on how, and to what extent, lacustrine pockmarks (e.g. crater-like depressions formed by upward transport of fluid and gas through the unconsolidated sediment column) affect the hydrological and biogeochemical budget of Swiss lakes.
