Postdoctoral Position in Orthopaedic Engineering

The Faculty of Engineering at the University of Southern Denmark (SDU) invites applications for one three-year postdoctoral fellow position in development of technology for orthopaedic surgery. This role combines medical imaging (ultrasound and MRI) computer-assisted surgical technologies and the study of how bones and joints move. The targeted starting date is March 1 2026 or as soon as possible.

The application deadline isJanuary 15 2026at 11.59 PM/23.59 (CET/CEST)

The successful candidate will work on a multi-stage project that aims to develop simple and cost-effective methods of measuring joint motion relevant to the planning of hip and knee surgery. This includes developing methods to reconstruct 3D anatomy from imaging measuring how joints move and creating planning tools that surgeons can use before and during an operation. The work brings together ultrasound MRI and optical tracking to guide the surgeon for example identifying the location where a cam deformity is causing impingement and how much bone to remove in hip arthroscopy or revealing how implant positioning affects patellofemoral tracking in knee arthroplasty.

The position is with the Biomedical Engineering Centre (BEC) Department of Technology and Innovation. The postdoc will join a growing interdisciplinary team working on practical solutions that improve surgical precision and clinical outcomes.

Job description and responsibilities

We are looking for a researcher who is excited about building practical technology that can help surgeons make more accurate patient-specific decisions during orthopaedic surgery. The role will involve working with tools that analyse how bones move during functional tasks but with a focus on improving the quality of the motion data itself. Although detailed joint models already exist in the literature these models are typically driven by motion captured from skin-mounted markers which introduce errors from soft-tissue artefact. By integrating ultrasound with MRI and high-precision tracking this project aims to capture much more accurate joint motion in individual patients allowing us to identify where bones impinge how joint clearance changes with movement and how different surgical decisions such as resection depth or implant rotation affect joint mechanics with greater precision than is currently possible.

The BEC is dedicated to fostering a diverse welcoming and inclusive research environment. We value people from all backgrounds and experiences and we actively support a culture where everyone can thrive. This post will be an important part of our friendly collaborative and energetic research group. The successful candidate will work closely with students academic colleagues and potential industrial partners contributing to a positive open and supportive research culture.

Responsibilities

Specific Duties

• Combine ultrasound MRI and optical tracking data to build accurate 3D models of bones and joints.
• Measure how bones move when a person moves and/or loads their joints (hip & knee) using imaging and tracking.
• Align (register) ultrasound images to MRI scans so the two sets of information match in 3D space.
• Create simple software tools that show surgeons where bones touch or impinge and how different surgical choices will change joint movement.
• Run accuracy tests using plastic models motion rigs and cadaver joints to check how well the system measures bone shape and motion.
• Prepare ethics applications and help recruit volunteers for studies.
• Set up and run demonstrations of the system for surgeons and other users and gather feedback on how it fits into real surgical workflows.
• Work with an external company to organise the customisation of ultrasound probes.

Additional Duties

• Manage your own research and contribute to coordinating project activities.
• Adapt existing methods and develop new protocols for imaging tracking and reconstruction.
• Analyse data from multiple sources and refine working hypotheses.
• Contribute ideas for new research directions and funding proposals.
• Help prepare scientific papers reports and presentations.
• Use specialist imaging and tracking equipment in laboratory settings.
• Advise colleagues on scientific and experimental techniques.
• Represent the research group at meetings workshops and conferences.
• Contribute to collaborative projects across SDU and partner institutions.
• Participate in teaching and supervision where appropriate.
• Assisting with other reasonable practical and administrative duties as required.

Selection criteria
