Full‑time position (100 %).
Start of employment: April 1, 2026
Duration of employment: 3 years
Position: PhD student in the Department for BioMedical Research at the University of Bern and the University Clinic of Rheumatology and Immunology at Inselspital, Bern.
Project Description
Solid cancers such as breast cancer, melanoma, and head and neck cancer remain major global health challenges due to their high incidence, aggressive progression, and limited treatment options. These tumors frequently metastasize or develop resistance to conventional therapies, contributing significantly to cancer‑related mortality and highlighting the need for innovative therapeutic strategies. Our group develops therapeutic cancer vaccines based on virus‑like particles (VLPs), which are highly immunogenic, non‑infectious structures that effectively activate immune cells to recognize and eliminate cancer cells. These vaccines can be tailored as personalized formulations targeting patient‑specific mutations or designed as universal vaccines applicable across tumor types. VLP‑based vaccination has the potential to induce strong and durable anti‑tumor immunity, offering a promising strategy within cancer immunotherapy.
The aim of this project is to develop novel therapeutic VLP‑based cancer vaccines using AI‑driven design approaches. The work will rely on both in vivo and in vitro experimentation, with a strong focus on evaluating immune responses, particularly B‑cell activation and complement involvement, in transgenic mouse models.
Essential technical skills:
* VLP‑based vaccine design, production and purification via ultracentrifugation (ÄKTA)
* Approved in vivo animal license (LTK) in Switzerland
* Experience with murine cancer models (subcutaneous and orthotopic)
* Expertise in platforms such as flow cytometry (Aurora), image mass cytometry, and single‑cell RNA sequencing
* AI‑based software for VLP design
Opportunities for scientific collaboration and exchange with research groups at the University of Bern as well as leading universities in China will be offered. The candidate will benefit from access to well‑equipped laboratories and state‑of‑the‑art core facilities.
Requirements
We are looking for a highly motivated candidate with a Master’s degree in life sciences or biomedical sciences and a strong background in immunology and cellular biology.
