Dr. Marion Pohlner
The main interest of my research are marine systems, especially (deep sea) sediments. Therefore, I joined two research cruises to the Pacific Ocean (SO248 and SO254) during my PhD project. I analyzed the composition of benthic microbial communities and the environmental conditions shaping those communities, with a special focus on the Roseobacter group and its biogeographical distribution. Within the framework of the recent project "MultiKulti - Cultivation of previously uncultivated microorganisms from different aquatic habitats" I´m interested in the abundance of Marine Group II Euryarchaeota with the goal to cultivate them. Next to research I coordinate the MultiKulti project, I´m involved in teaching and organisation of the master program "Microbiology" at the ICBM.
