Jobbeschreibung

The German Cancer Research Center (DKFZ) is one of Europe’s largest cancer research centers. “Research for a life without cancer\" is the mission of our world-class scientists and all our team members.

The DKFZ is a place where the brightest minds pursue bold ideas and seek answers to pioneering scientific questions through collaboration, innovation, and exploration across many disciplines. We provide a dynamic environment which empowers excellence with state-of-the-art technologies, cutting edge infrastructure, and a global scientific network.

Contribute your knowledge, vision, and dedication to create a space where scientific discovery in cancer research is transformed into benefits for human health.

Together with selected university partner sites, the German Cancer Research Center has established the German Cancer Consortium (Deutsches Konsortium für Translationale Krebsforschung, DKTK). The alliance between the DKFZ, as the core center, and the university partner sites in Berlin, Dresden, Essen/Düsseldorf, Frankfurt/Mainz, Freiburg, Heidelberg, Munich, and Tübingen joins forces at eight joint translation centers. The DKTK promotes interdisciplinary preclinical translational research topics to accelerate the transfer of results into new approaches for prevention, diagnosis, and treatment of cancer and to develop strategies for personalized oncology. The consortium supports the training of the next generation of medical and clinician scientists, operates state-of-the-art, highly specialized research infrastructures and technical platforms, and promotes the transfer of innovations to the economy and society.

For the Research Group "Adaptive Glycan Remodeling in Cancer Progression" (headed by Amulya Sreekumar) at the DKTK partner site Berlin, the DKFZ is seeking, starting in January 2027, a PhD Student in Cancer Biology.

Reference number: 2026-0184

We are seeking a highly motivated PhD student to investigate the mechanisms driving breast cancer progression. Approximately 30% of breast cancer patients who are disease-free after initial therapy ultimately develop local or metastatic recurrences seeded by therapy-evasive residual tumor cells. Such cells often exist in a dormant state and subsequently exit dormancy, thus giving rise to recurrences. We are interested in the molecular mechanisms that promote residual tumor cell persistence after therapy and their subsequent reactivation. Building on our recent discovery that tumor cell‑autonomous glycan biosynthesis supports dormant cell persistence, this project aims to identify therapeutic strategies that disrupt glycan‑mediated signaling to eliminate residual tumor cells and prevent lethal recurrence. The work will integrate mechanistic molecular biology, functional genomics, and advanced cancer models to achieve this goal.

The successful candidate will join the DKFZ International PhD Program (https://www.dkfz.de/en/career/international-phd-program) and work in a collaborative environment spanning DKFZ and Charité/DKTK Berlin. This partnership provides access to cutting‑edge core facilities, including high‑content imaging, flow cytometry, and genomics technologies at both institutions. Our laboratory is located within the Department of Hematology, Oncology, and Cancer Immunology at Charité‑Campus Virchow Klinikum in Berlin.
