Young Scientists Seminars

The SFB 754 young scientists seminar will be held on Tuesdays at 16:15h at the large conference room (GEOMAR, west shore building). There are two presenters (SFB754 PhD candidate and/or postdoc), each presentation lasts around 30 min including discussion. PhD candidates present the status of their PhD thesis, postdocs report on their research. The challenge of the presentations is to make it understandable to scientist of the various diciplines participating in the SFB 754. The SFB 754 young scientists seminars are open to any interested researchers.
