The laboratory of Prof. Dr. Daniela Duarte Campos at the Center for Molecular Biology (ZMBH) is seeking a

 PhD student – Xolographic biofabrication of in vitro vascularized tissue models (f/m/d)

For a collaborative project within the Cluster of Excellence 3D Materials Made to Order (3DMM2O). Our cluster combines the competencies of two Universities of Excellence, Heidelberg University and Karlsruhe Institute of Technology, to advance 3D Additive Manufacturing to the next level. 

Xolography offers a powerful new approach for fabricating in vitro vascularized tissue models. Unlike traditional layer-by-layer bioprinting, xolographic biofabrication enables true volumetric printing by intersecting light fields to generate entire 3D constructs within seconds. This rapid, contact-free process minimizes mechanical stress on encapsulated cells and allows the creation of intricate, perfusable vascular networks with high spatial resolution. Developing reliable vascularized tissue models is essential for advancing tissue engineering, disease modelling, and drug testing, as vascularization is key to maintaining cell viability and mimicking physiological function.

The Duarte Campos Lab investigates biofabrication technologies and biomaterials to engineer tissues and organs, and to understand their effects on the structure and function of living systems.

Your tasks will be to develop and characterize a vascularized in vitro tissue model. The work will involve a variety of techniques including but not limited to:

• natural and synthetic bioink preparation and handling; 
• 2D and 3D cell culture of primary human cells and cell lines 
• Xolographic fabrication of in vitro tissue models, including refining of printing parameters 
• Tune bioink stiffness and measure it with a nanoindenter 
• histological and immunofluorescence staining, two-photon imaging, qPCR 

Your profile:

• Master degree in Biomedical Engineering, Materials Science, Chemistry, Bioengineering or related disciplines

• Previous experience in hydrogel handling, 3D (bio)printing, microscopy, cell culture, and/or microfluidic systems are preferred

• Excellent achievements and English skills

• Motivation to work in an international environment as part of a team

 We offer an international and attractive work environment within the Duarte Campos Lab at the ZMBH and, as member of the 3DMM2O, you will have full access to modern state of-the-art infrastructure both at Heidelberg University and Karlsruhe Institute of Technology. The salary is based on TV-L scale (E13). The position is to be filled with 29,625 hours/week (75%) for two years, with the possibility of extension. The position is available to start in April 2026.

Applications should be sent to Prof. Daniela Duarte Campos (dcampos@uni-heidelberg.de) in one  single PDF-file that includes a letter of motivation, CV, copy of transcripts and name of 2-3 referees. We ask for your understanding that application documents received by post will not be returned.

Closing date for applications: November 28, 2025

Heidelberg University stands for equal opportunities and diversity. Qualified female candidates are especially invited to apply. Disabled persons will be given preference if they are equally qualified. Information on the application process and the collection of personal data is available at www.uni-heidelberg.de/stellenmarkt.
