PHD STUDENT POSITION IN ARTIFICIAL TUMOR IMMUE MICROENVIRONMENTS FOR IMMUNOTHERAPY SCREENING IN BREAST CANCER (F/M/D)

Starting on May 1st 2026 (with flexibility).

We have pioneered the development of synthetic tumor immune microenvironments engineered from artificial cells that mimic immune functions within tumors (Piernitzki et al. Nature Communications 2025). This platform enables the creation of artificial tumor microenvironments with precisely defined properties allowing systematic investigation of therapy resistance mechanisms particularly in solid this PhD project this approach will be applied to uncover how the tumor immune microenvironment differs between breast cancer tumors and metastatic lesions and how these differences shape varying responses to immunotherapies. To achieve this spheroid and organoid models will be combined with synthetic biology strategies and state-of-the-art molecular profiling to dissect the microenvironmental drivers of immunotherapy resistance.

Your roles:

• Investigate the role of the tumor immune microenvironment in breast cancer immune therapy

• Develop and form cancer spheroid and organoid cultures (from cell lines and primary patient cells) with artificial tumor immune microenvironments

• Engineer synthetic cells with immunological properties

• Perform in vitro assays for different immunotherapeutic modalities specifically focused on bispecific T cell engagers therapies and antibody-drug conjugates

• Isolate and culture primary human T cells to create CAR T cells

• Analyze RNA sequencing-based transcriptomic data sets

• Perform immune-staining with flow cytometry analysis advanced microscopy techniques (light-sheet microscopy confocal fluorescence microscopy) and biochemical assays to assess cancer phenotypes

Your profile:

• Master degree in cell biology biomaterials immunology cancer biology biophysics (or related fields). Experience in (3D) cell culturing fluoresence microscopy and RNA sequencing transcirptome anaylsis is ideal.

• Interest in working with an international and multi-disciplinary team. Self-driven and hands-on personality. Organization and prioritization skills.

• Very good communication skills in English.

We offer:

• An emergent hot research topic with multiple opportunities to contribute and interact with the growing community and indiustrial partners.

• An existing team with expertise and drive to move forward synthetic biology in cancer immunotherapy. A well-structured on-boarding process and clear responsibilities.

• A highly professional and supportive working environment with an open and international culture.

• Strong support of training and career development towards an outstanding profile at the intersection of cancer immunotherapy and biomaterials.

• Flexible working hours and mobile working opportunity.

• A EG 13 TV-L position and 3 year contract.
