Job description


The MathKOA research project
Osteoarthritis (OA) is one of the leading causes of disability worldwide1 with pain and reduced function as hallmark symptoms. OA can currently not be cured, and the available treatments are focused on improving symptoms. OA is a multi-scale and multi-factorial degenerative joint disease with knee OA (KOA) being the most frequent. Biomechanical factors play an important role in maintaining joint homeostasis and several early KOA interventions are aimed at altering the body-level biomechanics to reduce joint degeneration that occurs largely due to changes at the cell level. However, the relationship between levels, i.e. body, joint, tissue and cell, and its relationship to pain response, is currently poorly understood.

To tackle this challenge, we are bringing together mathematical modeling experts, whose combined expertise cover multi-scale modelling, including mechanobiology and experimental tissue characterization of bone, cartilage and tendons, with the world’s leading scientist in pain mechanisms in KOA to establish the first comprehensive predictive model of KOA, capturing also the interaction between loading and pain. In addition to a fundamental understanding, the mathematical model also enables personalized treatments based on the prediction of expected outcome.

Initially, we will develop in vivo measurement techniques and perform in vitro and ex vivo experiments to obtain model inputs. Hereafter, mathematical models of the body, joint, tissue and cell levels are researched and coupled to a pain response model to enable investigations of the relationship between KOA interventions and the multi-scale response. Rigorous validation is performed to evaluate the accuracy of the sub-level models as well as the predictive capabilities of the multi-scale model in a cohort study initiated during the project. Finally, the predictive capabilities of the model are applied to design novel, personalized KOA interventions with the ultimate goal to improve patient care.

MathKOA is a multi-national research project comprising partners from Aalborg University, University of Eastern Finland and Lund University and additional collaborators from Aalborg University Hospital and Massachusetts Institute of Technology that has received 50 mio DKK in funding from the Novo Nordisk foundation. The success applicant(s) will, therefore, have a unique opportunity to join a large and highly ambitious project within Mathematical modeling of KOA.

The PhD project(s)
Within the general scope of the MathKOA project as outlined above one or more PhD scholarships are available at Aalborg University. Four overall research topics are available, for which the applicants must indicate which (could be one or more topics) they want to be considered for. This must be included in the project description that the applicants must upload as part of the application. For all four overall topics the following required qualifications apply:

 Required qualifications

Research topic 2: Modeling of cartilage and meniscus properties from novel Medical Resonance Imaging (MRI)-based measurements

The purpose of this research topic is to create patient-specific knee models, capturing the mechanical properties of cartilage and meniscus in vivo. To this end, the research will also include development of a MRI-compatible loading device to obtain loaded and unloaded MRI images from which to identify the cartilage and meniscus strain under the specific load. This information is subsequently converted to a patient-specific computational model of the knee and used to identify differences in healthy and KOA cartilage and meniscus properties.

Required qualifications

Research topic 3: Template-based MRI segmentation for multi-scale modeling

The purpose of this research topic is create novel MRI segmentation algorithms to extract bone, cartilage and ligament information from MRI images of healthy and KOA patients to be applied for patient-specific computational modeling. This research will explore template-based approaches to reduce (or ideally fully remove) time consuming, manual tasks when segmenting medical images with a focus on creating seamless interfaces to patient-specific computational models of the lower extremity.

 Required qualifications

  • Software programming experiences (e.g. C, C++, Python and/or Matlab).

Desired qualifications

  • You have experience with manual and/or (semi) automatic segmentation of medical images.

Thereby, as an employee at the Department you will become a part of an international research environment, where focus is on innovation, knowledge sharing/building and interdisciplinary collaborations.

Job description

This PhD position is supported financially by the Department of Materials and Production, Center of Industrial Production (CIP). CIP are comprising of 12 senior researchers and 15 PhD students. Its objective, among other things, is to study Operations Management in the industrial and services industries. A new and growing research area is Healthcare Operations which is also supported through a collaboration with Aalborg University Hospital.

This research focuses, among others, on establishing data fundaments (through exploiting the existing and identifying new data sources) and analytics as a basis for surgery planning and control of resources and capacities. A cross organizational perspective is expected (e.g. through the involvement of related departments/functions/staff, such as bio-chemical laboratory, radiology, anaesteciology, secretarial and surgical staff and patients). The ultimate goal is improvement of the operational performance  along with reduction of waiting times in the patient flow. Several aspects contribute to underutilization of surgery capacity:  Scheduling done based on accumulated tacit knowledge and, sometimes, incomplete information, uncertain estimates of surgery durations, hospital policies, poor data quality in management information systems. Literature introduces various models for surgery duration modelling and estimation, and for surgery planning and scheduling. The goal of the PhD project is to contribute to operational performance and positive employee and patient outcomes by combining or developing new analytics approaches, taking into account the numerous data sources that exist in a modern healthcare setting. The project will be conducted in collaboration with Aalborg University Hospital.

The application for the position should contain a project proposal specifying research idea and motivation, brief outline of relevant theoretical background, and suggestions for scientific methodology, considering the application of Artificial Intelligence techniques such as Deep Learning and Machine Learning, but also thoughts on collection and validation of data and challenges, and how to implement new models to the benefit of the hospital.

The ideal candidate has demonstrated:

  • Application of mixed methods combining qualitative and quantitative methods.
  • Prior experience with application of data science, operations research or operations management concepts in a health care setting.
  • Ability to work in a multi-disciplinary environment as an independent researcher.
