Researcher in Biogeochemical modelling

Deadline: 31.05.2023

Norwegian Institute for Water Research

The Norwegian Institute for Water Research (NIVA) is Norway's leading research institute for the aquatic environment, working across a wide range of environmental, climate and resource issues. Our high-quality research is characterised by its relevance, and its holistic and interdisciplinary approach, combining research with monitoring, assessment, problem solving and consulting. The NIVA group has approximately 500 employees and is headquartered in Oslo, with branches in Bergen, Grimstad, Hamar and Copenhagen, together with a marine research station in Drøbak, and subsidiaries in Tromsø, Chile and China.

NIVA is looking for a researcher in the field of process-based modelling of natural systems in the catchment-lake-coast continuum. The candidate will join the section for Catchment biogeochemistry, consisting of 15 researchers focusing on transport and cycling of nutrients, carbon and contaminants in catchments, lakes, rivers and coastal areas. The section develops, maintains and applies NIVA’s state-of-the-art Mobius model development platform. Modelling is a crosscutting theme between several of NIVA’s science groups and the chosen candidate will be included in a strong interdisciplinary team.

The workplace will be NIVA’s main office in Oslo (with possibilities to move to one of the regional offices after 1-2 years).


  • Use process-based physical and biogeochemical models to describe and predict the impacts of changes in climate, land use and land management on catchment processes, riverine element transport, lake biogeochemistry and ecology, and coastal systems
  • Contribute to and develop NIVA’s Mobius modelling platform
  • Spatial analysis, databasing and statistical analyses
  • Participate in national and international research projects and contribute towards project acquisition
  • Reporting of project activity, including written and oral presentations in English and/or Norwegian to a range of audiences


  • MSc and/or PhD in relevant discipline
  • Competence and strong expertise in the use of process-based models of aquatic systems, including catchments, lakes, rivers and/or coastal areas
  • Strong coding skills (e.g. in Python)
  • Well-qualified in English (written and oral)


  • Knowledge and experience in biogeochemistry (carbon, nutrients, contaminants in catchments, lakes, rivers, and/or coast)
  • Interest in mathematical modeling and development of process-based models
  • Experience in statistics and algorithms for conducting model sensitivity and uncertainty analyses
  • Spatial analysis (e.g. geopandas, ArcGIS) and databasing (e.g. SQL)
  • Experience in project management
  • Experience with interdisciplinary working
  • Mastery of a Scandinavian language (written and oral)

Personal abilities

We are looking for an enthusiastic, outgoing and positive colleague that can manage several tasks simultaneously in a structured way. Our new colleague will work in several Norwegian and/or international projects and it is important that you are prepared to work as part of a team. The right candidate will find motivation from working in an interdisciplinary scientific research environment covering a broad spectrum of topics. In addition, creativity in solving problems and innovating new ideas are important skills.

NIVA offers

  • Exciting and stimulating tasks in a leading national water research institute with great societal significance
  • An opportunity for professional and personal development in an organization where responsibility and initiative are highly valued
  • Flexible working hours, good pension, welfare and insurance schemes, and competitive salary
  • To be part of a network of national and international researchers
  • Personal development opportunities
  • A multicultural, social, and creative work environment
  • Holiday cabin in the mountains of Hemsedal

Inclusion and diversity NIVA’s work environment is distinguished by respect and equality. We treat each other equally and do not discriminate based on gender, age, functional ability, religion, ethnic and cultural background, or any other defining aspect of an individual. We wish to attract diversity as different perspectives promote innovation and we encourage all qualified candidates to apply for positions at NIVA regardless of age, gender, functional ability, nationality, or ethnic background.
