DC 1 – Generation of a virtual twin for the human brain accounting for region- and age-dependent properties

1. Overview of the research programme:

InSilicoHealth is an innovative Doctoral Network (DN) with the ambition to train a new generation of outstanding
Doctoral Candidates (DC) that will become effective translators of the rapidly evolving digital technology to tackle
existing and future challenges related with healthy ageing in Europe. The research focus of this DN lies in three
key domains: the brain, heart, and musculoskeletal (MSK) systems. In the realm of digital technology, InSilicoHealth
specifically focuses on virtual human twin (VHT) technology to enhance our understanding of the age-related adaptive
changes of the complex human body through predictive multi-scale simulations. The research methodology employs
knowledge-driven models enhanced by advanced data-driven inference techniques to optimize the health potential of
older individuals.

3. PhD project description:

This PhD project will focus on generating a full-scale human brain finite element model that accounts for regional
and age-related changes in the mechanical properties of brain tissue. The objectives are: 1) Examine the regional
and age-related variations in the tissue structural parameters; 2) Assess the changes in the brain tissue mechanical
properties due to ageing and disease; 3) Develop age-dependent material models for the different regions of the
brain integrating previously generated data (mechanical data, microstructural data from histological images, and in
vivo structural data from magnetic resonance and diffusion tensor imaging); 4) Implement the material models into
full-scale brain models; 5) Perform benchmark simulations of brain atrophy related to healthy ageing and diseases.
A successful project can result in an improved understanding of the changes in the mechanical properties of the
brain tissue due to ageing and potentially neurodegenerative diseases (e.g., Alzheimer and Parkinson), novel Finite
Element models of the ageing brain incorporating human data, and curated dataset for healthy ageing studies.

4. Planned secondments:

  • KTH Neuronic Engineering: Aims to gain knowledge in the generation of person-specific finite element models of
    the ageing brain.
  • Siemens Healthineers: Opportunity for the DC to gain knowledge on the integration of in silico technologies in
    an industry setting.

5. Essential requirements:

  • You have completed a master’s degree in Mechanical/Civil Engineering, Computational Engineering, Biomedical
    Engineering, or possess corresponding qualifications that could provide a basis for successfully completing a
    doctorate.

    (Germany) for more than 12 months in the three years before 1st of January 2025.
  • You are ambitious, well organized, a team player, and have excellent communication skills.
  • You can work independently and have a critical mindset.
  • You are a pro-active and motivated person, eager to participate in network-wide training events, international
    mobility, and public dissemination activities.
  • Previous experience in Finite viscoelastic constitutive modelling, Finite growth modelling, nonlinear finite
    element modelling, and/or hybrid modelling as well as coding experience in C++ and Python is not required but
    considered a plus.
