Supervision in cooperation with the University Bremen, POLMAR, Earth System Science Research School (ESSReS), and the Postgraduate Programme Environmental Physics (pep). We cannot teach people anything; we can only help them discover it within themselves (Galileo Galilei) (some hints for thesis writing and for the committees ).
