PhD Position (100%): Design Optimisation of Orthopaedic Implants in Zürich

ETH Zurich is one of the world’s leading universities specialising in science and technology. It is renowned for its excellent education, its cutting-edge fundamental research and its efforts to put new knowledge and innovations directly into practice. Three collaborative PhD positions are available at the Institute for Biomechanics (Department of Health Sciences and Technology).

The available position is funded under the EU MSCA Innovative Training Network program "NuSpine". The overall aims of the research program are to develop and characterise new biomaterials (i.e. silicon nitride) for use in spinal implants in order to improve mechanical load-bearing capacity, decrease the rate of implant wear and increase the stability of osseointegration. Through material and design optimisation, we aim to extend the functional longevity of spinal implants in an increasingly active patient population.

The focus of this research sub-project is the optimal design of implants, with the following objectives: (1) Implementation of semi-automated topology optimisation in a public-domain, voxel-based finite element solver (ParFE), including the specific pre- and post-yield properties of silicon nitride materials. (2) Application of topology optimisation to develop novel forms of intervertebral fusion implants, targeting maximum implant porosity, homogeneous loading of the host bone and accelerated cell proliferation rate.

We look forward to receiving your online application including a specific statement of motivation for the project, your CV and a copy of your university transcripts as PDFs. Please address your application to Dr. Benedikt Helgason. Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
