This fully funded interdisciplinary PhD studentship invites an ambitious researcher to contribute to the development of next‑generation bone tissue engineering solutions using advanced 3D biofabrication techniques. The project focuses on the Freeform Reversible Embedding of Suspended Hydrogel (FRESH) additive manufacturing approach, an innovative bioprinting technique that enables the creation of mechanically robust and structurally precise constructs by printing bioinks into a sacrificial support bath that preserves shape fidelity throughout the process.

You will design and synthesise novel bioinks based on polyphosphate gels produced via sol‑gel chemistry and coacervation, which are formulated to possess regenerative, antibacterial and anti‑inflammatory properties suitable for promoting bone repair. These bioactive scaffolds are intended to mimic the porous architecture of trabecular bone, encouraging formation of hydroxyapatite in physiological environments and supporting osteoblast attachment and proliferation.

The research integrates a comprehensive array of characterisation techniques — including electron microscopy (SEM and TEM), thermal analysis, gas physisorption, X‑ray diffraction and synchrotron‑based X‑ray absorption spectroscopy — to assess structural and morphological properties of materials. You will also evaluate cytocompatibility through cell culture testing with osteoblasts. Throughout this project, you will gain hands‑on experience in advanced fabrication methods such as 3D printing and electrospinning, alongside high‑end material analysis and cell biology techniques. The multidisciplinary nature of the work bridges materials science, chemistry, biology and medicine, offering broad training and a strong foundation for a career in biomaterials research and regenerative medicine.

Eligibility Criteria
Candidates must hold, or expect to obtain, a first‑class or upper second‑class honours degree (2:1) or equivalent in a relevant scientific discipline such as biomaterials science, chemistry, physics, chemical engineering or materials science. A strong interest in bio‑/nanomaterials and interdisciplinary research is essential.

Required Expertise, Skills
The ideal candidate will demonstrate solid foundational knowledge in materials science or related disciplines, enthusiasm for experimental research, and a willingness to develop skills in 3D biofabrication, biomaterials characterisation and cell culture. Experience in laboratory work and familiarity with analytical techniques will be beneficial.

Salary Details 
This studentship provides full coverage of home and international university fees, additional funding for research training and travel, and a UKRI standard maintenance stipend of £20,780 per year for the 2025/26 academic year. Funding is provided for a period of 3.5 years through an EPSRC studentship.

Application Deadline 
The deadline for applications is 20 March 2026.
