Degree Awarding Institution: University of Graz
You will take part in a joint project between Sano Science Institute, University of Graz and University of Sheffield and will be guided by a world class team from these institutions. Your PhD degree will be awarded by the University of Graz.
Ideally a candidate should possess a 1st Class undergraduate Honours degree or a Master’s degree (completed or near completion) in a relevant discipline, such as computational mathematics(preferred), physics, biophysics, biomedical physics, or biomedical engineering with a strong mathematics background.
Supervisors:
The primary question to be addressed in this project is whether electrophysiological heterogeneity at both structural and functional levels can be incorporated in digital cohort/twin models of the whole human heart. If so, how are we to approach this in Digital Twin models considering two particular examples of inhomogeneous conductance:
- i) that due to the arrangement of myocardial fibres;
- ii) that due to the Purkinje network.
The aim is to investigate the degree to which structural and functional heterogeneity of conductance at the tissue level affects organ (system) level cardiac dynamics. To this end, methodologies should be devised with the purpose of implementing such heterogeneity using realistic parameterized models and investigating the resultant system dynamics. The phase space of system behaviour is to be discerned and quantified, including specific sensitivity to key parameters in order to provide guidelines on how to incorporate heterogeneity at tissue level in the preparation of patient specific Digital Twin Hearts.
Automatic generation methods and software tools drawing on data available from atlases, ex vivo scanning data and possible imaging techniques anticipated to be available in the near future must be prepared. This is particularly important for identifying the parameters and parameter ranges capturing most controllability/sensitivity in the system, and is thus deemed absolutely essential for the success of the personalized Digital Twin Hearts.
