Teaching

The professors and senior scientists of the department of marine geodynamics teach at Christian-Albrechts-University of Kiel. Their lectures are part of the undergraduate course Physics of the Earth System and the graduate courses Master of Geophysics and Master of Marine Geosciences. More information is available at https://www.ifg.uni-kiel.de/en/studies. We offer MSc and BSc thesis supervision. Please get in touch if you would like to learn more about possible thesis projects. Either check with the most appropriate researcher or with Heidrun Kopp (hkopp(at)geomar.de) or Christian Berndt (cberndt(at)geomar.de).
