We offer a fantastic range of benefits including a highly competitive annual leave entitlement (with the ability to purchase more), a generous pensions scheme, flexible working opportunities, a commitment to your development and wellbeing, a wide range of retail discounts, and much more. Find out more about our benefits (opens in a new window) and join us to become part of something special.

Overview

This highly interdisciplinary position will focus on the modelling of paediatric bone across a wide age range (0-16 years) through the creation of digital twins based on paired CT and MRI scans. This novel work will significantly advance our understanding of bone strength and associated fracture risk during development. The position is funded as part of an EPSRC project that aims to develop and validate paediatric bone models through a combined computational and experimental approach, in collaboration with clinical partners at the Sheffield Children’s Hospital. 

The ideal candidate will have an excellent PhD in biomechanics (or a related discipline), possess a solid knowledge of non-linear finite element modelling, have a strong experience in developing and validating patient-specific biomechanical computational model, and have some experience in scientific programming such as Python. You will join the group of Dr Xinshan Li, Professors Damien Lacroix and Enrico Dall’Ara, as part of the Integrated Musculoskeletal Biomechanics (IMSB) group within the INSIGNEO Institute, which has an international and interdisciplinary profile and a strong commitment in clinical translation. You will actively participant in the IMSB group and INSIGNEO activities. You will also sustain and strengthen collaboration within relevant INSIGNEO research groups and beyond; and will commit to INSIGNEO’s mission to produce high quality cutting-edge research. 

Main duties and responsibilities

●      Lead the development of subject-specific finite element models of paediatric femora bone and rib samples to evaluate bone strength.

●      Lead the development of approaches to model both the mineralised and non-mineralised materials in developing bones.

●      Effectively work with colleagues for the segmentation of paediatric femora bone and rib samples from paired MRI and CT images.

●      Effectively work with colleagues for the registration of mineralised and non-mineralised bone materials to develop subject-specific finite element models.

●      Work collaboratively with other colleagues for the validation of the finite element models of rib samples based on in situ mechanical testing data.

●      Lead the model uncertainty quantification for femora and rib samples.

●      Effectively work with colleagues for the identification of in vivo and ex vivo biomarkers for low bone strength associated with lower levels of vitamin D.

●      Follow best practices for quality assurance of research software and effective management of research data.

●      Participate in patient and public involvement and engagement activities.

●    Self-organise time to ensure the achievement of the objectives agreed with the line manager and to continue to develop own knowledge in the domain of research.

●      Maintain up-to-date knowledge of the relevant literature.

●      Effectively collaborate with colleagues, clinicians, partners, etc. to achieve the agreed objectives.

●      Proactively seek to develop further collaboration opportunities arising from own work.

●      Be actively engaged and participate to all meetings and activities in the IMSB group and at the INSIGNEO Institute.

●      Mentor junior colleagues and PhD students and supervise MEng/MSc dissertation research.

●      Interact with other researchers within the School, the INSIGNEO Institute, the rest of the University and the collaborating NHS hospitals.

●      Write papers that are published in internationally peer-reviewed journals.

●      Present work at national and international conferences.

●      Write technical reports both for internal monitoring and for reporting to external funding agencies.

●      Make ethical decisions in your role, embedding the University sustainability strategy into your working activities wherever possible.

●      Carry out other duties, commensurate with the grade and remit of the post.
