Fully Funded PhD Studentship in Mechanics-Informed Design of Reinforced Interventional Catheters
About the Project
Applications are invited for a fully funded PhD position in the area of reinforced flexible interventional catheter design and digital manufacturing at School of Mechanical and Materials Engineering, University College Dublin (UCD), Ireland.
Project Overview
Flexible interventional catheters are widely used in cardiovascular, neurovascular, and peripheral vascular interventions. Their key functional properties, including pushability, torque transmission, flexibility, and kink resistance, are largely determined by the design of their internal reinforcement structures.
This PhD project focuses on the design theory and manufacturing technologies of coil-reinforced and braided-reinforced catheter structures. By integrating finite element modelling, experimental characterisation, and data-driven optimisation, the project aims to establish quantitative relationships between structural parameters and mechanical performance, enabling predictive design and digital engineering of next-generation interventional catheters.
The successful candidate will work at the intersection of mechanics, advanced manufacturing, medical device engineering, and computational design.
Funding and Research Environment
This project is jointly supported by:
- I-Form, the Research Ireland Centre for Advanced Manufacturing
- MNMT-Dublin, the UCD Centre of Micro/Nano Manufacturing Technology
- An Irish medical device company
The student will benefit from close collaboration between academia and industry and will gain exposure to both fundamental research and real-world medical device development.
Upon successful completion of the PhD, opportunities may be available to apply for competitive Irish and European research fellowships or pursue a career within the collaborating medical device industry.
Supervisory Team
The academic supervisor, Prof Jufan Zhang, is a Principal Investigator at the MNMT-Dublin Centre, and a funded investigator at the I-Form and CURAM (Research Ireland Centre for Medical Devices).
The supervisory team has a strong track record of mentoring researchers who have subsequently secured prestigious European and Irish fellowships, including Marie Skłodowska-Curie Fellowships, Research Ireland Industry Fellowship, or taking leadership positions in high-technology companies.
The industrial supervisor will be the CTO of the collaborating medical device company.
