PhD Research Fellow in Applied and Computational Mathematics - VISTA Center

for Modeling of Coupled Subsurface Dynamics

The Department of Mathematics has a vacancy for a PhD position in scientific computing with start date between 1. April and 1. November 2022. The position is for a fixed-term period of 3 years with the possibility of a 4th year with compulsory other work (e.g. teaching duties at the Department).The position is part of the recently established Center for Modeling of Coupled Subsurface Dynamics (VISTA CSD, https: // www. uib.no/en/vista-csd). VISTA is a basic research programme financed by the Equinor and executed in close cooperation with The Norwegian Academy of Science and Letters. The center involves approximately 40 people, including faculty, researchers, postdocs and PhD and master students.

About the project/work tasks:

Production of hydrocarbons and geothermal energy, extraction of groundwater, subsurface energy storage, CO2 sequestration and wastewater disposal all involve massive subsurface extraction and/or injection of fluids. This affects the thermal, hydraulic, mechanical and chemical (THMC) state at depth, resulting in strongly coupled THMC processes. In recent years, the surface manifestations fluid injection and production have become increasingly apparent.

To improve engineering operations and avoid unacceptable environmental impact, there is a need to understand how fluid injection and extraction effects the mechanics of the geological formation to cause deformation of porous rocks as well as slip, opening and propagation of fractures and faults. These processes can be studied by a combination of data analysis and mathematical modeling and simulation.

VISTA CSD's primary objective is to develop fundamental knowledge and educate next generation researchers to understand how subsurface fluid injection and extraction results in deformation, fault reactivation and fracturing. The center thus targets critical and fundamental research questions through mathematical and numerical modeling and data analysis.

The present position considers solvers for linear and non-linear problems arising from the discretization of multiphysics problems in fractured porous media, as provided by the simulation software PorePy (https: // github.com/pmgbergen/porepy/). The project goal is to develop methods for automatized selection of robust and efficient solvers for such multiphysics problems. This will involve defining solver strategies, including splitting, stabilization, preconditioning and acceleration, based on characteristics of the problem at hand. To this end, a combination of mathematical analysis and on-the-fly learning will be applied. An important project goal is to develop an open-source software.

Qualifications and personal qualities:
  • Applicants must hold a master's degree or equivalent education in applied and computational mathematics, scientific computing or computer science. Master students can apply provided they complete their final master exam before 31 October 2022. It is a condition of employment that the master's degree has been awarded.
  • Education at master's level and strong expertise in scientific computing, solvers for linear and / or non-linear problems is a requirement.
  • Excellent programming skills are a requirement.
  • Experience with numerical methods for partial differential equations is an advantage.
  • Experience in algorithms for parallel computing is an advantage.
  • Applicants must be able to work independently and in a structured manner and demonstrate good collaborative skills.
  • Applicants must be proficient in both written and oral English.
  • In the assessment of relevant candidates, a holistic assessment of both quality and breadth in the candidates' background will be carried out. Personal and relational qualities will be emphasized.

    About the PhD position (applies to university PhD positions):

    The fellowship will be for a period of 3 years, with the possibility for a 4th year, consisting of 25 % compulsory work (e.g. teaching responsibilities at the department) distributed over the employment period. The 4th year is contingent on the qualifications of the candidate and the teaching needs of the department and will be decided by the head of department upon appointment.

    The employment period may be reduced if you have previously been employed in a qualifying post (e.g. research fellow, research assistant).

    About the research training

    As a PhD Research Fellow, you must participate in an approved educational programme for a PhD degree within a period of 3 years. The deadline for applying for admission to the PhD programme at The Faculty of Mathematics and Natural Sciences is 2 months after you start your position or after the start of the research project that will lead to the PhD degree. It is a condition that you satisfy the enrolment requirements for the PhD programme at the University of Bergen.

    We can offer:
  • a good and professionally stimulating working environment
  • salary at pay grade 54 (Code 1017/Pay range 20, alternative 10) in the state salary scale. This constitutes a gross annual salary of NOK 491 200. Further promotions are made according to length of service in the position.
  • enrolment in the Norwegian Public Service Pension Fund
  • good welfare benefits
  • Your application must include:
  • a brief account of the applicant's research interests and motivation for applying for the position
  • the names and contact information for two referees. One of these should be the main advisor for the master's thesis or equivalent thesis
  • CV
  • transcripts and diplomas showing completion of the bachelor's and master's degrees. If you have not yet completed your master's degree, please submit a statement from your institution confirming the expected date of award of your master's degree. Your master's degree must be documented with transcripts and/or diploma, alternatively a confirmation from your institution on completed degree and your grade, by 31. October 2022. relevant certificates/references
  • approved documentation of proficiency in English (if required, cf. English language requirements for PhD admission)
  • a list of any works of a scientific nature (publication list)
  • any publications in your name
  • The application and appendices with certified translations into English or a Scandinavian language must be uploaded at Jobbnorge.

    General information:

    For further details about the position, please contact Senior Researcher Eirik Keilegavlen, e-mail: Eirik.Keilegavlen@uib.no.

    The state labour force shall reflect the diversity of Norwegian society to the greatest extent possible. Age and gender balance among employees is therefore a goal. It is also a goal to recruit people with immigrant backgrounds. People with immigrant backgrounds and people with disabilities are encouraged to apply for the position.

    We encourage women to apply. If multiple applicants have approximately equivalent qualifications, the rules pertaining to moderate gender quotas shall apply.

    The University of Bergen applies the principle of public access to information when recruiting staff for academic positions.

    Information about applicants may be made public even if the applicant has asked not to be named on the list of persons who have applied. The applicant must be notified if the request to be omitted is not met.

    Further information about the employment process can be found here.
