The University of Bergen invites applications for a PhD Research Fellow in Applied and Computational Mathematics, hosted by the Department of Mathematics and affiliated with the Center for Sustainable Subsurface Resources (CSSR). This is a 3-year, full-time position, with the possibility of a 4th year dedicated to career development activities such as teaching. The position is funded by the University of Bergen and offers a competitive salary (NOK 568,700 per year), pension, and welfare benefits. The successful candidate will join CSSR, a national research hub funded by the Norwegian Research Council, focused on developing digital solutions to reduce Norway’s offshore emissions. The research project centers on the development, analysis, and implementation of new nonlinear iterative solvers for multi-model analysis and simulation of subsurface operations. The work will involve high-performance computing, reduced-order models, and data-driven (machine-learned) representations, with a particular interest in integrating simpler models into full-physics simulations. The project combines theoretical foundations from numerical and functional analysis with practical applications in fluid mechanics and porous media. Applicants must hold (or be about to complete) a master’s degree in applied and computational mathematics, scientific computing, or a closely related field. Required qualifications include experience with functional analysis or analysis of partial differential equations. Additional experience with preconditioning, non-standard nonlinear solvers, and numerical methods for fluid mechanics or porous media is advantageous. Candidates should demonstrate strong independent and collaborative working skills, as well as proficiency in written and spoken English. Admission to the PhD programme at the Faculty of Science and Technology is required within two months of starting the position. The position offers exciting development opportunities in a strong professional environment, with the possibility of a 4th year for career-promoting work. The University of Bergen is committed to diversity and encourages applications from all qualified candidates, including women, individuals with disabilities, and those with immigrant backgrounds. For further information, contact Professor Jan Martin Nordbotten ([email protected]) or researcher Eirik Keilegavlen ([email protected]). Applications must be submitted online via Jobbnorge, including all required documents and references, by 1 February 2026.

PhD Research Fellow in Applied and Computational Mathematics at the University of Bergen, Department of Mathematics, with a research focus on modeling and simulation for giga-scale CO2 storage. The position is hosted by the Porous Media Group, a research group working on numerical and computational methods for processes in porous materials, with a particular emphasis on geological applications. The project is part of gigaCCS, a Norwegian Research Council-funded center for environmentally friendly energy research and large-scale carbon capture and subsurface storage. The successful candidate will contribute to Work Package 3.1, “Regional storage scale-up,” and will work on the impact of macro dispersion on the efficiency of large-scale storage operations. Research topics may include upscaling, discretization methods, numerical analysis, and the design and implementation of numerical methods in open-source scientific computing software. The methods developed will be tested on setups relevant to storage formations in the North Sea. This makes the position particularly attractive for candidates interested in computational mathematics, porous media flow, numerical modeling, and CO2 storage applications. The appointment is for 3 years, with a possible 4th year depending on the candidate’s qualifications and the department’s teaching needs. If granted, the 4th year includes career-promoting work such as teaching, dissemination, or research infrastructure/services. The position is funded by UiB and offers a salary as a PhD research fellow in the state salary scale, currently NOK 593 700 per year before taxes, plus pension enrollment and welfare benefits. Eligibility highlights: applicants must hold a master’s degree or equivalent in applied and computational mathematics, scientific computing, computational physics, or computational geoscience. Master students may apply if they will complete the final exam before 1 March 2027. Required experience includes partial differential equations and related discretization methods, as well as mathematics of flow in porous media. Good English skills, independence, structured working style, and collaboration skills are expected. Experience with computational science software development is advantageous. Application requirements are extensive and include a short account of research interests and motivation, a detailed qualification statement addressing each requirement and listed advantage, names and contact information for two referees, CV, transcripts and diplomas, English proficiency documentation if required, thesis or thesis draft, and a list of scientific works/publications. Applications and certified translations must be uploaded via Jobbnorge by 5 November 2026.
