Simula Research Laboratory

Oslo

We are pleased to announce a new PhD Research Fellowship in the Department of Numerical Analysis and Scientific Computing at Simula Research Laboratory, in connection with the research project DigiCells: Next-generation digital twins for biological cell environments.
Simula is a leading Norwegian research institute known for its excellence in cutting-edge ICT with a strong track record of top evaluations, active international collaborations, and success in significant funding initiatives, including European and National RCN grants. Simula is committed to supporting talent through a variety of PhD and postdoctoral programs and provides valuable research infrastructure, such as the national HPC facility, eX3. In a recent evaluation by the Research Council of Norway, the Scientific Computing section at Simula was described as “clearly close to world leading in computational neuroscience and cardiology,” and was ranked among the top three research groups in Norway out of 248 evaluated.
Job description
We are looking for a PhD candidate to join our team to work on topics related to computational modelling, simulation and learning of excitable tissue dynamics.
Recent advances in imaging and computing have together revolutionized our ability to study the structure and function of living systems. The DigiCells ambition is to establish algorithmic and technological foundations for next-generation modelling and analysis of biological cell environments that integrate geometric structure, biophysical dynamics, and high-resolution cell imaging data. The project is multidisciplinary bridging between and across scientific computing, machine learning, computational mathematics, bioimaging, stem cell research, cardiology and neuroscience
The PhD candidate is expected to conduct research within the following areas:
<ul><li>
scalable algorithms for the numerical solution of partial differential equations
</li><li>
scientific machine learning for algorithm acceleration and modelling
</li><li>
application of such methods and tools in the computational neurosciences
</li></ul>
At Simula, the candidate will work in a vibrant, excellence-oriented, and collaborative research environment led by Marie E. Rognes. In addition to the candidate, the DigiCells team will include several research scientists, research engineers, national and international partners. The PhD candidate is expected to be enrolled in the PhD program at the Faculty of Mathematics and Natural Sciences at the University of Oslo, a premier European research environment that combines a rich academic heritage with a forward-looking perspective.
Candidate Profile
We will consider candidates who have completed (or will have completed by August 1 2026) a Master’s degree (or equivalent) in mathematics, computer science, physics, or other relevant disciplines. We are in particular looking for candidates with a strong computational mathematics or scientific machine learning background. Proficiency in a high-level programming language (e.g., Python, Julia, C++) is essential. Experience in neuroscience is not required, but interest in the application of computational methods in the life sciences is considered an advantage. Previous experience with multilevel methods such as multigrid is relevant.
The purpose of this 3-year fellowship is research training leading to the successful completion of a PhD degree. Please read the PhD program information and the specific grade and language admission requirements.
