The University of Cologne is seeking a postdoctoral researcher to investigate the regulation of endolysosomal super-organelles in mouse oocytes and how their function deteriorates during reproductive aging. The successful candidate will engage in proteomic and lipidomic analyses, as well as oocyte isolation, microinjection, and imaging. The position offers opportunities to develop and lead an independent research project in a collaborative environment, with the potential to supervise students and contribute to cutting-edge research on protein homeostasis in reproductive biology. A PhD in Biology, Biochemistry, or a related field is required, along with experience in proteostasis, animal models, and/or oocyte manipulation.
