PhD position - Predicting the stress field in atherosclerotic plaque of arteries using scientific machine learning within the HDS-LEE graduate school

We are looking for a PhD student to develop learning-based surrogate models for predicting stress fields in patient-specific arteries. Especially high stresses in plaque can lead to rupture, which is one cause of a stroke and thus the prediction of plaque rupture is very relevant. The steps in the development of surrogate models are building data-driven models from medical imaging, extending them with physics-based approaches, and adapting existing physics-integrated neural network approaches for stress prediction in arterial walls and plaque. Another part of the project is exploring the use of large language models to support neural network design and data preprocessing. The position involves close collaboration with experts in cardiovascular simulation and Scientific Machine Learning. Your tasks:

• Development and comparison of data driven models for the prediction of stresses in arterial walls and plaque
• Enhancing the models with physics, i.e., using different physics-aware machine learning models from the field of scientific machine learning
• Exploiting large language models to support neural network design and data preprocessing
• Participation in conferences in Germany and abroad (incl. presenting your research results)
• Preparing scientific publications and project reports, We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We offer ideal conditions for you to complete your doctoral degree:
• Outstanding scientific and technical infrastructure
• Highly motivated groups as well as an international and interdisciplinary working environment at one of Europe's largest research establishments
• Continuous scientific mentoring by your scientific advisors
• Chance of participating in (international) conferences
• Unique HDS-LEE graduate school program (including data science courses, soft skill courses and annual retreats) https://www.hds-lee.de/about/
• A qualification that is highly welcome in industry
• 30 days of annual leave and flexible working arrangements, including partial remote work
• Further development of your personal strengths, e.g. via a comprehensive training program; a structured program of continuing education and networking opportunities specifically for doctoral researchers via JuDocS, the Jülich Center for Doctoral Researchers and Supervisors: https://www.fz-juelich.de/judocs
• Targeted services for international employees, e.g. through our International Advisory Service

The contract will be with Forschungszentrum Jülich, but the daily place of work will be at University of Cologne in the group of Prof. Dr. Axel Klawonn, with temporary periods at Forschungszentrum Jülich in the group of Dr. Andreas Herten.

The position is limited to three years, with a possible one-year extension. Pay is in line with 75% of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund) and additionally 60 % of a monthly salary as special payment ("Christmas bonus"). The monthly salaries in euro can be found on the BMI website: https://go.fzj.de/bmi.tvoed.entgelt
