The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people.


For the Laboratory for Waste Management – Transport Mechanics group and within the scope of a research project funded by SwissNuclear we are looking for a


Postdoctoral Fellow in AI-enhanced modelling of boiling multiphase flows


Your tasks

  • • Develop and extend the in-house GPU-accelerated multiphase Lattice Boltzmann (LBM) code for DNS-grade boiling multiphase flow related to nuclear reactor operation, including bubble dynamics and wall interaction phenomena
  • • Implement AI/ML models and multiscale coupling procedures to bridge the lattice Boltzmann codes with a two-fluid Eulerian macroscopic code
  • • Co-development of codes, including benchmarking and validation
  • • Publication of results in journals and conferences

Skills/Qualifications

Your profile

We are looking for a team player able to work independently with

  • • PhD degree in Mechanical or Nuclear Engineering / Natural Sciences / Environmental Sciences
  • • Experience in modelling fluid dynamics and multiphase flows (ideally with lattice Boltzmann method)
  • • Strong experience in programming (C/Cuda/Python). Familirarity with AI/ML methods for scientific computing and openness to explore different approaches
  • • Very good command of English is required (spoken and written)

Benefits

  • • Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
  • • Employment contract is initially limited to 2 years, with possible extension depending on the performance and future project availability.

Additional comments

  • • For further information, please contact Dr Nikolaos Prasianakis, phone +41 56 310 24 15.
  • • Please submit your application online by 6 March 2026 (including list of publications and addresses of referees) for the position as a Postdoctoral Fellow (Index-Nr. 4403-26147).
