For centuries, the so-called Viking Age (c.750-1050 CE) has been subject to political misappropriation and projected, monochrome stereotype – making it all the more urgent to emphasise that the people of the time were individuals as varied and complicated, in every way, as ourselves. This spotlight on diversity, in all senses of the term, lies at the heart of the WIVA Centre: our objective is to recover a Viking Age that does not care what we think of it, a pluralistic past as it was (hard though that can be to access), not as anyone might wish it to have been. The notion of a Norse diaspora has now become commonplace in studies of the period, but also requires deconstruction. Our focus is the world in the Viking Age, an arena of mutual interactions, contacts and cultural feedback, subtly different from the more familiar ‘Viking world’. Moving past the Eurocentric notions of a ‘western’ and ‘eastern’ Viking Age, it is possible to perceive the finer grain of Scandinavian cultural encounters. We aim to explore the full span of the extended, Afro-Eurasian world of the Norse, looking primarily south and east along the so-called Silk Roads, tracing their activities in networks of early globalisation that connected the Baltic to the Mediterranean, the Indian Ocean, Asia, and the eastern seas – places where the Scandinavians were as often in a minority, but also at a disadvantage.

We are now seeking to appoint two postdoctoral Early Career Researchers to full-time positions, fixed-term for two years. Duties include up to 20% teaching and supervision, alongside 80% dedicated to personal research on themes related to the Centre.

In parallel with these postdoc positions, we are also seeking a number of International Visiting Researchers (advertised separately), and more posts of both kinds will be added over time. A new interdisciplinary, two-year MA degree programme will also be launched, again addressing the same theme of the world in the Viking Age. All these activities will be supplemented by seminars, workshops, informal contact events, and public outreach. Finally, WIVA is an invitation, not a fixed entity. The Centre is not a research project, but rather a home and a hub for them, as well as a base for teaching. We will populate WIVA with projects, programmes, and people, and we hope that others will wish to join us on this exciting journey.

Most rivers are heavily influenced by humans. In many places, rivers are therefore being restored to promote water quality and biological diversity. Construction of wetlands and dam removal are two common measures, and both lead to an increased abundance of macrophytes, i.e. plants in or near water. Macrophytes can emit significant amounts of greenhouse gases, but at the same time also bind carbon and thus constitute a carbon sink. The CLIMIPHY project aims to create new knowledge about the climate footprint of macrophytes that gives river restoration professionals the opportunity to restore watercourses in a way that favors biodiversity and water quality, with as little climate footprint as possible.

The postdoctoral researcher will work in an exciting sub-project that uses new drone technology to perform field measurements the emission of greenhouse gases from river restoration areas. The work takes place in close collaboration with other project team members, and under joint supervision together with meteorologists at the Department of Earth Sciences: https://www.uu.se/en/department/earth-sciences/research/air-water-and-landscape-science/meteorology

Are you an expert in experimental techniques using fast neutrons? Do you want to work with the support of competent and friendly colleagues in an international environment? Are you looking for an employer that invests in sustainable employeeship and offers safe, favourable working conditions? We welcome you to apply for a postdoc position at Uppsala University.  

The position is located within the Department of Physics and Astronomy, Division of Applied Nuclear Physics. Here we conduct research in the field of nuclear science and connect fundamental nuclear physics research with applications in nuclear technology. Examples of our research areas are experimental studies of nuclear fission, neutron spectrometry for plasma diagnostics in fusion, nuclear data evaluation methodology, and technical aspects of nuclear safeguards and disarmament.  

We are looking for a postdoctoral fellow to be stationed at the SuperADAM instrument at ILL, Grenoble. SuperADAM is the only fully Swedish owned and operated neutron instrument. It is a high-resolution polarized neutron reflectometer suited for magnetic, hard condensed matter and soft matter, as well as life science investigations. The duties of the successful candidate include the support of users on the instrument, to conduct his/her own research, as well as to work with the continued development and upgrade of the instrument. Besides functioning as a beam line scientist, the postdoctoral fellow is expected to develop his/her research, within the areas soft matter, magnetism or similar, which will be performed both at ILL and the three partner universities (Uppsala, Lund and Linköping). The research direction is mostly determined by the expertise and interests of the candidates, but experience of neutron scattering of interest for Swedish users of SuperADAM is presupposed. This research should ideally build on and expand existing collaborations between the ILL and the three partner Universities, and thereby exploit capabilities in Grenoble, (e.g. the partnership for soft condensed matter ( http://www.epn-campus.eu/users/partnership-for-soft-condensed-matter-pscm/) and/or in Sweden, (e.g. thin film deposition and x-ray reflectivity characterization). An interest in the use of magnetic reference layers, as well as off-specular scattering, are examples of possible strength areas that utilize the capacity of the instrument.

We are looking for a postdoctoral fellow with a strong background in software development, or software developer with a strong interest in science. You will join a new project, within which applied statistics and information theory is used to quantify the information content of neutron reflectivity datasets. Using this, we are able to optimize the design of experiments and to make previously impossible experiments possible, as well as to run existing experiments faster and better.

In a facility where a typical experiment lasts few days, costs tens of thousands of pounds/Euros and takes 6+ months to apply for, any improvements to the experiment are of large value. The effort will be based on an existing code-base we have developed to design optimal thin film structures for a given purpose. These structures will be fabricated by other members of the collaboration and measured using a variety of methods including neutron reflectivity experiments. Participation and collaboration with all other parts of the project is strongly encouraged and if the candidate chooses, they can participate in the large-scale facility experiments.

The code-base is released as an open-source project, with an emphasis on sustainable software engineering (https://github.com/jfkcooper/HOGBEN) and has two journal articles published.  Significant development of the capabilities of the code-base is required. These will include improvements to the experimental design code, as well as improving the data analysis, applying Bayesian methods for extracting parameter uncertainties and model selection. The developments will allow the entire collaboration to move forward, suggesting optimal materials systems to be investigated and designing experiments for the other nodes of the project.

The position is based in Sweden but involves shorter as well as extended stays in the UK and France, working at ISIS and ILL. Visits to ESS are also assumed. There will be the opportunity for overseas travel to meet international collaborators, and to present the work at workshops/conferences.

Participate in the design and construction of superconducting magnets. Hands-on preparation of cold tests of magnets and cavities. Plan and monitor measurements, troubleshoot experiment setups, and operate the cryogenic and vacuum infrastructure. Report on and document the activities.

In addition to the magnet-related activities, the candidate will assist in the overall development and evaluation of instrumentation and experiments at the FREIA Laboratory. Active contribution to outreach activities and to the supervision of students is expected. The work will involve domestic and international travel.

Campus Gotland is an international campus in the UNESCO World Heritage city of Visby on the island of Gotland in the middle of the Baltic Sea.

The postdoc position is part of the new Horizon Europe project, “BioEcoOcean – Co-Creating Transformative Pathways to Biological and Ecosystem Ocean Observations (Grant agreement 101136748). Dr. Nordlund coordinates this four-year project, which aims to improve coordination and collaboration in ocean observations, with a special emphasis on biology and ecosystems. The project engages stakeholders from across Europe and globally to create a Blueprint for Integrated Ocean Science, designed to promote workflows that align with FAIR Data Principles, ensuring more effective and consistent biology and ecosystem ocean observation.

BioEcoOcean advocates a transformative approach to biology and ecosystem ocean observation to deepen our scientific understanding, improve management practices, and promote the sustainable use and development of the ocean. It utilises “living labs,” collaborative workspaces dedicated to co-creation and innovation. Each lab has a different focus area, and the research is expected to integrate existing resources, observations, and models while creating new pathways to achieve project goals. Collaboration is a core element, with a diverse range of partners including researchers, civil society, administrators, industry, other EU projects, the Global Ocean Observation System IOC-UNESCO, among others.

On Gotland, there will be two co-creation living labs. The living lab most relevant for this position is the Blueprint living lab. The research will be particularly solutions oriented, identifying pathways for more interoperable and collaborative approaches in biology and ecosystem ocean observations. The Blueprint living lab is leading the work on creating the Blueprint for Integrated Ocean Science that aims to connect all components of the ocean observing value chain, from planning to policy and beyond. The research will require engaging stakeholders globally.

Collaboration within the BioEcoOcean consortium will be of utmost importance, and especially collaboration on the iterative process on developing the Blueprint. Several workshops, webinars, surveys will be conducted during the project. On Gotland, also as part of the BioEcoOcean project there will be a Baltic Sea living lab, where another postdoc will be hired. Close collaboration between the postdocs is expected. 

The postdoctoral fellow will be involved in designing, planning and executing workshops, surveys, data collection as well as data analyses. The postdoctoral fellow is expected to produce high-quality scientific articles suitable for scientific publication in high-profile journals and for presentation at national and international conferences. The research results are also expected to contribute to the BioEcoOcean project”s broader goals and deliverables. Teaching may also be included in up to 20% of the duties in employment as a postdoctoral fellow.

The project is focused on the thermal and radiological characteristics of spent nuclear fuel (SNF), which are crucial for its safe and secure storage. This research will delve into the source term, which is pivotal in determining essential fuel parameters such as decay heat, criticality, and dose rates. The outcomes are vital for ensuring safety, security, and cost-effective engineering design of disposal facilities.

The source term of SNF from small modular reactors (SMRs) may differ from that of traditional nuclear reactors. Addressing these differences is imperative for the integration of SMRs into the current reactor fleet.

This research project aims to develop advanced methods for better characterizing the SNF from both current reactors and SMRs, with a special emphasis on criticality issues. Building on previous work , the project will tackle new challenges associated with SMRs, contributing significantly to the safe and secure management of SNF from these innovative reactors.
