Postdoctoral fellowship available in Scientific Computing at Simula Research Laboratory

Simula Research Laboratory AS is a publicly owned research laboratory located in Oslo, Norway. Simula’s mission is to solve important and fundamental problems of science and engineering, with the main goal of benefiting and advancing society. Simula conducts Information and Communication Technology (ICT) research in the fields of scientific computing, software engineering, communication systems, machine learning and cybersecurity. Job description: In the Department for Scientific Computing and Numerical Analysis at Simula, we now have an opening for 1 Postdoctoral fellow to join our research project: aCleanBrain - BRAIN FLUIDS - TRANSPORT AND CLEARANCE. The successful candidate will join the aCleanBrain core research team consisting of several other PhD candidates, Postdoctoral fellows, senior researchers as well as national and international collaborators, and become an integral part of the large, vibrant and open research environment within scientific computing, applied mathematics and computational physiology at Simula. The aCleanBrain research project is all about developing new mathematics, algorithms, and software tools in order to better understand the process of brain clearance, in particular during sleep. This project is a highly interdisciplinary project involving collaborations with medical experts, scientific software development, the use of both traditional simulation methods such as finite element methods as well as machine learning in order to answer deep questions of basic brain functions. The research questions require deep mathematics in terms of novel numerical analysis, advanced scientific software development, and new models of the physics of brain fluids. While a Postdoctoral fellow does not need deep competence in all aspects, such a modeling challenge can only by a team with members of different expertise. Scientific breakthroughs in neuroscience attempt to explain the need for sleep and the develop- ment of neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases in terms of fluid dynamics: the waste created during the day is cleared away as we sleep or it accumulates. However, a decade of research after the original theory was posed has revealed that the underlying physical mechanisms are still not understood and that advanced mathematical tools are needed. In this project we propose a research program addressing: new fluid dynamics mechanisms novel numerical analysis for advanced multi-physics brain simulations a framework for patient-specific simulations. We will exploit reduced order and machine learning methods in addition to finite element solutions. With successful delivery, aCleanBrain will establish the main drivers of brain fluid dynamics, provide a foundation for accurate, efficient and robust algorithms for multi-physics problems and develop a software framework for advanced biomechanical brain simulations. We are looking for candidates with a solid track record contributing to one (or more) of these aims. The aCleanBrain project is funded by the ERC advanced grant funding scheme. Keywords: Postdoctoral fellow, scientific computing, simulation, HPC, neuroscience, Simula Candidate profile: We are looking for candidates for a 2-year Postdoctoral fellowship. Candidates should have a solid background in applied mathematics, scientific computing, computational science, bioengineering or related fields, and an interest in contributing to neuroscience. Candidates must have successfully completed their PhD degree by no more than 6 months after the starting date. Successful candidates should have the following qualifications: A theoretical and/or computational background in applied mathematics, scientific computing, computational life science or bioengineering with knowledge of numerical methods for differential equations; A strong track record (commensurable by career level) including excellent academic results; Strong programming skills as well as experience with high-level languages (such as Python, Matlab or Julia). Documented knowledge of brain physiology or an interest in studying, learning and discussing this subject. We expect a solid track record of research including high quality scientific publications. Simula offers: An excellent environment and outstanding opportunities for performing high quality research as part of a highly competent, motivated and enthusiastic team of researchers and engineers. An informal and inclusive international working environment Modern office facilities located in the heart of Oslo with an extensive public transport network within a few minutes walk and a vibrant city life right outside the office door steps. A competitive salary, with a starting range of 595.000 NOK for Postdoctoral fellows. Generous support for travel and opportunities to build international networks, through established collaborations with industry, exchange programs and research visits with other universities, and funding to attend conferences.
