We are seeking a highly motivated PhD student to join the Translational Pediatric Oncology Research Group of Prof. Dr. Christian Braun at the Department of Pediatrics (Director: Prof. Jan-Henning Klusmann), University Hospital Frankfurt.

Our group investigates how dysregulated gene-expression programs contribute to the development and progression of pediatric cancers, with the overarching goal of identifying new therapeutic vulnerabilities. We combine advanced CRISPR-based screening approaches with transcriptomic and proteomic profiling and employ patient-derived cancer models to uncover the molecular mechanisms that drive high-risk tumors.

The successful candidate will become part of an interdisciplinary and collaborative team committed to translating molecular insights into new precision-oncology strategies for children with cancer.

The position is initially limited to one year, with the possibility of extension.

Your Role:

• Design and perform CRISPR-based genetic perturbation screens in patient-derived and engineered cancer models
• Analyze and interpret epigenetic, transcriptomic, and proteomic datasets using state-of-the-art statistical and computational approaches
• Functionally validate candidate genes, pathways, and molecular mechanisms in cellular model systems
• Contribute to the development and preclinical evaluation of targeted therapeutic strategies for high-risk pediatric tumors
• Present results within the research group and at scientific meetings, and contribute to publications
• Collaborate closely with clinicians, molecular biologists, and computational scientists within an interdisciplinary environment

• Master’s degree in Life Sciences or a closely related field with an excellent academic record
• Strong interest in uncovering novel therapeutic strategies and in understanding epigenetic and transcriptional mechanisms of gene regulation
• Practical experience with standard molecular biology techniques (e.g., cloning, PCR, flow cytometry)
• Basic proficiency in bioinformatics and experience analyzing high-throughput datasets (e.g., RNA-seq, proteomics)
• Motivation to work independently as well as collaboratively within an interdisciplinary research team
• Excellent communication skills and proficiency in written and spoken English
• Due to legal regulations, valid proof of measles immunity / measles vaccination is required

• In addition to an attractive salary based on a collective agreement (TV-G-U, E13) with an annual special payment, you benefit from long-term security through company pension schemes
• The position is part time 26h/week, initially limited to one year, with the possibility of extension.
• Internal and external training for your professional development
• Benefit from our attractive health offers. We offer regular online and face-to-face courses on nutrition, relaxation, sports and exercise
• Part-time employment is possible, we offer childcare in our daycare center (if you have any questions, please contact UKF-Familienservice), child care during holidays
• Free public transport in all Hessen (Free State Ticket Hessen)
• Uniklinik-Campus, Mensa, Cafés
• Insights: Instagram, YouTube, LinkedIn
• FAQ´s for new employees
