Umeå University is one of Sweden’s largest higher education institutions with over 37 000 students and about 4 700 employees. The University offers a diversity of high-quality education and world-leading research in several fields. And the groundbreaking discovery of the CRISPR-Cas9 gene-editing tool, which was awarded the Nobel Prize in Chemistry, was made here. At Umeå University, everything is close. Our cohesive campuses make it easy to meet, work together and exchange knowledge, which promotes a dynamic and open culture.
The ongoing societal transformation and large green investments in northern Sweden create enormous opportunities and complex challenges. For Umeå University, conducting research about – and in the middle of – a society in transition is what it is all about. But also about delivering education to enable regions to expand quickly and sustainably. This is simply where the future is built.

The Department of Ecology and Environmental Science at Umeå University, Sweden, seeks a postdoctoral researcher who will work with evaluating landform restoration in mining waste rock in a paraglacial environment. The employment is full-time for three years with a start date of 1 August 2023 or by agreement. Application deadline is 9 June 2023.
Morphometry of landforms and channel networks in paraglacial landscapes are largely poorly understood, which can have implications for landform restoration. Successful restoration requires a full understanding of the natural landscape to obtain appropriate reference areas regarding channel dynamics and sediment transport. Currently, newly rehabilitated landscapes lack detailed monitoring programs to evaluate geomorphic processes in paraglacial landscapes. The extractive industry in Sweden currently has ~177 km2 of mining disturbed land, composed largely of waste rock (WR) storage. The currently accepted industry solution for WR storage prioritizes efficient deposition over environmental goals, but such storage facilities, due to hillslope and fluvial processes, may erode and become unstable. In this project, we will evaluate another approach, using a geomorphic design approach to create long-term, stable landforms in dynamic equilibrium, by routing water through a designed natural channel network. Achieving a long-term stable landform provides the foundation for ecological recovery including high biodiversity and a landscape usable for future generations. These objectives will be achieved through understanding morphology and dynamics of hillslopes and stream networks in paraglacial landforms in northern Sweden. The postdoctoral project is within a larger project ‘Waste2Place’, composed of a multi-disciplinary team of geomorphologists, ecologists, landscape architects, and representatives from four mining companies. The postdoctor will be involved in two work packages: WP2- Landscape assessment, aiming to quantify the geomorphology of paraglacial landscapes in northern Sweden, with a focus on stream channel network organization and related hillslopes using a combination of remote sensing techniques and field work; and WP5- Landscape performance monitoring, examining landform and channel evolution over the project period using high-resolution digital elevation data and sediment flux data. The goal through these WPs, together with other WPs focused on ecological recovery, is to develop a Swedish-centric geomorphic reclamation toolkit.
Project advances: We anticipate that the postdoctoral fellow will make key advances in understanding paraglacial landforms and channel network patterns in northern Sweden, including consideration of climate change impacts on WR storage facilities by; 1) determining the effect of surficial geology in paraglacial environments on channel morphology and network patterns, 2) quantifying characteristics of paraglacial landforms and drainage networks in boreal Fennoscandia, and 3) evaluating effects of climate change on hydrological drivers affecting landforms and drainage networks. The postdoctor will also make key advances in understanding how geomorphic-rehabilitated landscapes function in terms of erosion, sediment transport, and stability in such settings by 1) evaluating morphologic changes in a geomorphically-designed landscape in waste rock and 2) comparing its results with those obtained in a conventional restoration and a natural reference site, using multitemporal topographic surveys and hydrological and sedimentary stations.
The postdoctoral Fellow will be placed in the Department of Ecology and Environmental Science at Umeå University, and will be advised by Dr. Lina Polvi Sjöberg and co-supervised by Dr. Ignacio Zapico Alonso and Professor José Francisco Martín Duque (Universidad Complutense of Madrid). The candidate will be expected to collaborate with a multidisciplinary team composed of consulting companies and mining companies, including Vast, Ecogain, Boliden, and LKAB.
To qualify as a postdoctoral fellow, the candidate is required to have completed a doctoral degree or a foreign degree deemed equivalent to a doctoral degree. This qualification requirement must be fulfilled no later than at the time of the decision about the position.
Priority should be given to candidates who completed their doctoral degree, according to what is stipulated in the paragraph above, no later than three years prior. If there are special reasons, candidates who completed their doctoral degree prior to that may also be eligible. Special reasons include absence due to illness, parental leave, appointments of trust in trade union organizations, military service, or similar circumstances, as well as clinical practice or other forms of appointment/assignment relevant to the subject area.
The doctoral degree should be in one of the following fields: earth science, geology, geomorphology, physical geography, or equivalent.
Essential criteria are:
- Strong skills in surveying, processing and analysing high-resolution topographic data (SfM-LiDAR)
- Strong skills in various GIS tools and analyses
