As part of the English-language course, Catalysis for Sustainable Synthesis (CaSuS), the doctoral students research in nine research groups of the Göttingen Faculty of Chemistry and five research groups of the TU Braunschweig on interdisciplinary projects in the field of catalytic chemistry. The topics of the research projects range from the design of new molecular catalysts and the elucidation of basic reaction mechanisms to the synthesis of polymers and natural products with a focus on industrial application. Many of the projects require close interdisciplinary collaboration between individual research groups. The intensive support and critical discussion of the results at joint events enable rapid progress in the work.
