Postdoctoral position at the Laboratory for Bone Biomechanics, ETH Zurich

Postdoctoral Position in Time-lapsed Imaging and Multiscale Modeling of Human Bone Fracture Healing

The aim of the research is to perform time-lapsed high-resolution CT imaging and multiscale modeling of distal radius bone fractures in patients and to investigate the in vivo healing process employing image processing and analysis. Bone fractures are very common and in 5-10% of the cases do not heal or are delayed. Nevertheless, factors influencing the healing outcome are not yet well understood. The specific aims of this 2-year project will therefore be (1) to perform high-resolution CT imaging in fracture patients and develop image analysis and registration methods to determine in vivo bone resorption and formation sites during fracture healing at the human distal radius, (2) to assess local bone remodeling and comparing the results with clinical biomarker measurements including whole bone strength through multiscale modeling approaches, and (3) to evaluate how bone remodeling during fracture healing affects whole bone strength in healthy, aged and osteoporotic humans.

The position will be based at the Inselspital Bern and at ETH Zurich. Furthermore, this project is embedded in a larger effort funded by the National Science Foundations of Switzerland, Germany, and Austria through a DACH consortium grant consisting of Ulm University (D), the Medical University Innsbruck (A), and the Inselspital Bern and ETH Zurich (CH). The overall goal of the consortium is to investigate local bone remodeling and mechanoregulation of bone fracture healing in healthy, aged, and osteoporotic humans.

The successful candidate holds or will soon receive a doctoral degree in Biomedical, Electrical or Mechanical Engineering, and has preferentially a background in imaging and image processing. It is essential that the candidate is willing and motivated to work at the interface between engineering and clinical research. Additionally, excellent communication skills in English (oral and written) are required and command of the German language is required for the clinical interactions.

We look forward to receiving your online application includinga a motivation letter, CV, university transcripts and names and contact details of two references. Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.

PhD position in FE musculoskeletal modelling at LBMC in Bron, France

PhD Position: Contribution to the improvement of a FE neck model for robust and bio-fidelic simulations

 

Context

The LBMC develops 3D Finite Element (FE) models to study the behaviour of the human body for applications in crash injury risk assessment, ergonomics and clinical orthopaedics. In these last two contexts, LBMC’s ‘Biomechanics and Ergonomics’ and ‘Biomechanics and Orthopaedics’ research teams have been developing subject-specific musculoskeletal models that aim at representing a virtual subject together with its physiological or pathological state. The EC funded DEMU2NECK project resulted in the development of a detailed FE model of the human neck within this framework. Results from this work allowed to identify the potential benefits of modelling 3D muscular actions (as opposed to 1D lines of action as is currently the case) to better account for the complex biomechanical loading that takes place within the cervical spine during tasks of the daily life. This potential may especially concern our ability to better model subject-specific characteristics, including for example a possible degradation of the muscular functional capacity resulting from either pathology or ageing. Benefits may thus be expected within applications regarding the assistance to the design of medical devices such as spinal implants and prostheses, by contributing to foster the development of ‘in-silico’ clinical trials, but also through the transfer towards applications related to ergonomics or virtual testing for the injury risk assessment of the vehicle occupant in poorly defined out-of-position scenarios (e.g. to better account for the driver’s postural behaviour in a pre-crash phase in the case of future autonomous vehicles).

Objectives

In order to support the development of such applications and ultimately of their use within virtual biomechanical or clinical trials, it is necessary to pursue the work already initiated to ensure the robustness of the active muscle model. This work targets both the numerical verification and the model validation as part of a VV&UQ (Verification Validation and Uncertainty Quantification) framework that is currently developed at LBMC trough a formalised multi-team research effort on the topic. This effort is also supported by Ifsttar through the funding of a MSc student industry placement at LBMC.

The PhD Thesis work will thus focus on the following objectives:

– Improve the robustness of the FE neck muscle model. Accounting for the active part of the muscle in a FE model remains a novel and challenging task, and this objective forms the core of the expected exploratory research and dissemination work. It may target several aspects:

  • The evaluation and improvement of the mechanical formulation and implementation of the active muscle model currently implemented in the LSDyna FE code (i.e. a coupled passive 3D matrix/1D active Hill-type elements),
  • The evaluation and estimation of task-related patterns of activation/muscle force distributions through a parallel FE/rigid-body co-simulation calculation loop,
  • The contribution to the gathering of dynamic in-vivo muscle validation data to help better validate the above predicted muscle force distributions. –

– Further pursue the integration of the subject-specific geometric personalizing approaches that have already been developed at LBMC, for use with medical imaging,

– Further improve the validation and bio-fidelity of the model, and apply it to the study of case-studies of pathologies (such as degenerative muscular pathology or cervical dystonia) and to the comparative predictive evaluation of a range of technical or surgical designs used in cervical arthrodesis or arthroplasty.

About InSciTe:

This position is part of the Chemelot Institute for Science & Technology (InSciTe), a public-private institute for developing smart healing biomedical materials for high quality, affordable healthcare. With its physical nucleus at Brightlands Chemelot Campus, it enables entrepreneurship, expertise, experimentation and education in an open innovation network. In this project, the founding partners, MUMC+, TU/e and DSM will work together with other partners to achieve their aim of bringing a new treatment for scoliosis to first-in-man trials.

Job description

In earlier work, the partners developed a new strategy for the treatment of scoliosis (an abnormal curvature of the spine) in growing children. With this strategy, ultra-high molecular weight polyethylene fibres are used in combination with metal rods to correct the spinal deformity. The number of levels to be treated, as well as the placement of fixation screw, however, are dependent on the severity of the deformation and other patient-specific factors. In order to optimize the design, a computer model is developed based on the finite element method. This model can represent the spine and the instrumentation and can be made to fit the patent by adjusting a limited number of parameters. The aim of the project is to develop this model into a pre-clinical and a patient-specific pre-operative tool to optimize the treatment. As these suggestions for optimization involve other parts of the project, there will be close interaction with the entire team.

POSITION DESCRIPTION
-Research Project / Research Group Description:

The proposed PhD will involve the Biomechanics and Mechanobiology (BMMB) and the Machine Learning for Personalised Medicine areas of BCN MedTech. BCN MedTech focuses on biomedical integrative research, including mathematical and computational models, algorithms and systems for computer-aided diagnosis and treatment of health problems. It has 60 full time researchers working on computational simulations, image analyses, signal processing, machine learning, and biomedical electronics.

Early cartilage degradation in osteochondral systems is poorly understood. In early osteoarthritis (OA), new theories point out the involvement of subchondral bone structural and mechanical changes [1]. In the IVD, the hyaline cartilage adjacent to the subchondral bone shows the first signs of ageing [2], and numerical explorations by the BMMB team have pointed out that specific subchondral bone structures induce above-average fluid velocities in the adjacent cartilage [3]. Thanks to the coupling of continuum tissue models and cell biology models, the BMMB team has recently demonstrated that early degradation of the IVD osteochondral layer is likely to result in the propagation of degenerative changes in the organ [4].

Accordingly, this project will explore new common paradigms of early OA and IVD degeneration processes through mechanistic modelling of the relationships among tissue interstitial fluid flow, chondrocyte mechanostimulation, inflammation and cartilage extracellular matrix turnover. It will involve finite element poromechanical models, and agent-based models of chondrocyte biological activity in different physical and biochemical environments. Model assessment will be achieved through experimental data on articular cartilage biology and multiphysics in OA patients, though an ongoing collaborative project with the Hospital del Mar, and though collaborations with the Universites of Zaragoza and Liège. Simulation results will be analysed through interpretable machine learning techniques.

-Job position description:

The successful candidate will work in a highly international environment in interaction with biomechanicians, biologists and computer scientists. He/She will be in charge of developing an intracellular network model for the simulation of chondrocyte mechanosensitivity in different inflammatory and nutritional environments, based on generic systems biology Boolean models. He/She will also handle multiphysics poromechanical models of the cartilage tissue matrix available at UPF to simulate the mechanical environment of the chondrocytes, simulated as agents. Sensitivity analyses, model evaluation and result interpretation will involve state-of-the-art techniques for model uncertainty evaluation and parameter/result classifications through in-house interpretable machine learning theories. He/She will actively participate to internal research seminars and international conferences in fields related with biomedical engineering, biomechanics, systems biology and rheumatology.

Candidates are expected to have a bachelor and master degrees in biomedical engineering, physics, applied mathematics or any related fields. They should be able to work in a team environment and have good communication skills. Proficient English is mandatory. For any inquiry, please contact Dr Jerome Noailly: Jerome.noailly@upf.edu

PhD position @ University of Portsmouth: 4D microCT evaluation and digital volume correlation of alloys for bone regeneration

4D microCT evaluation and digital volume correlation (DVC) of Mg-based alloys for bone regeneration

Project Description

Start date: 01 February 2018
Application deadline: 31 December 2017
Interview date: week commencing the 15th January 2018Applications are invited for a fully-funded, three-year PhD studentship at the University of Portsmouth, to commence at the beginning of February, 2018. This PhD is in collaboration with Botiss Biomaterials and the successful applicant will get the opportunity to work as part of a multi-disciplinary team that brings together expertise in biomaterials for bone tissue regeneration, X-ray computed tomography (XCT), in situ mechanical testing and digital volume correlation (DVC). The candidate will benefit from support in Biomechanical Imaging available at the Zeiss Global Centre (ZGC) in the School of Engineering. Professor Gordon Blunn (University of Portsmouth) and Dr Mike Barbeck (Botiss Biomaterials) complete the supervisory team.

Project
Mg-based biomaterlals are able to provide structural support in load-bearing regions and allow bone regeneration to take place over time. However, uncontrolled degradation rate in vivo could result in insufficient mechanical stability during regeneration. Recently, high-resolution microCT imaging combined with in situ mechanical testing (4D evaluation) and digital volume correlation (DVC) allowed a detailed assessment of local microdamage progression, as well as the quantification of 3D deformation in bone-biomaterial systems. However, to date the mechanical competence of Mg-bone integration in vivo is still unknown. The aim of this project is to investigate how the mechanical behaviour of Mg-based implants is influenced by dissolution time and osteoregeneratlon performance. The project will ultimately produce fundamental knowledge aiming at fully establishing Mg-based alloys in the clinical context, through the development of a new generation of products for orthopaedic applications.

Candidate specification
Applications from candidates with a background in biomechanics, biomaterials, X-ray tomography, mechanical testing or related subject areas are welcomed. The successful applicant will receive adequate training and support to develop the necessary skills for a successful completion of the programme. We are seeking to appoint an enthusiastic and committed candidate with excellent interpersonal and organisational skills.

Fees
The fully-funded, full-time three-year studentship provides a stipend that is in line with that offered by Research Councils UK of £14,553 per annum as well as a waiver of tuition fees. The successful candidate will also receive full access to the University’s Graduate School Development Programme, research training, and internal qualifications that enable applications for Associate Fellowship of the Higher Education Academy.
