17 Postdoctoral Fellowship at Stockholm University, Sweden

The position will be associated with the project Black Holes from Core-Collapse Supernovae. This project aims at the development and execution of state-of-the-art (and next generation) computational tools for simulating core-collapse supernovae, with a particular focus on black hole formation and the multi-messenger signals produced from these extreme environments.

The research project is entitled, “Breaking the Inequality-Crime Cycle: Biases in Police Decisions, ‘What Works’ in Prison, and Firm Demand for Workers with Criminal Records”. The project is funded by the European Research Council with Prof. Randi Hjalmarsson (Gothenburg University) as the PI and Prof. Matthew Lindquist as the local research coordinataor at SOFI, Stockholm University.
 
Economic inequality and segregation imply vastly unequal opportunities in many dimensions – the labor market, healthcare, informal networks, exposure to police – that can impact the chances of ending up in trouble with the law. Once caught in the justice system, it can be hard to break free, especially if a criminal record increases the barriers to employment. This cycle of crime and economic inequality can even be perpetuated across generations, if the impacts of a criminal record spill-over to an offender’s family members. 

The postdoctoral fellows will conduct original research on time-domain astronomy, with an emphasis on our upcoming involvement in the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST). One position, with Ragnhild Lunnan, is funded by an ERC starting grant; the other two positions, with Jesper Sollerman, is funded by a Wallenberg Foundation research grant and will also involve participating in transient classification with the Nordic Optical Telescope as part of Stockholm University’s in-kind contributions to the LSST project.

The successful candidates will be part of the Oskar Klein Centre (OKC; www.okc.albanova.se) in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics. The OKC hosts a vibrant research program on dark matter, dark energy, transient and multimessenger astrophysics, galaxy evolution, structure formation, and related particle physics questions. Postdoctoral fellows are also welcome to participate in Scientific Programs at the Nordic Institute for Theoretical Physics, Nordita.

The positions are an exciting opportunity to be part of a team leveraging Earth system science for transformative change towards sustainability. They will be associated with the project “Capturing and measuring multiple and systemic environmental impacts of companies and investments: a new tool that accounts for climate, water and biodiversity and their interactions” funded by the Swedish Research Council Formas. This project has two overarching goals: (a) to advance assessment of interactions between the planetary boundaries (see e.g. doi.org/10.1038/s41893-019-0454-4) and (b) to use this knowledge to refine and implement an “Earth system impact score” (doi.org/10.1088/1748-9326/ac2db1) for companies and investors. The project involves a large team (10+ people) of collaborators at Stockholm Resilience Centre at Stockholm University, the Royal Swedish Academy of Sciences, the Australian National University and the University of New South Wales. The position may also involve opportunities to interact with other international networks such as the Earth Commission.

The project “Baltic Fish” is funded by the Axel F and Vilna Lindmarkers’ Foundation for two researchers specializing in fish and fisheries issues in the Baltic Sea for five years. The project aims to promote and support the development of current fisheries management in a more sustainable direction, with increased focus on rebuilding and long-term sustainable management of Baltic Sea fish stocks. Through various communicative efforts, the aim is to increase public awareness of fishing issues and meet the needs of fisheries management and policy for sound and scientifically substantiated knowledge on various issues related to fishing and the status of fish stocks in the Baltic Sea.

The selected researchers will collaborate with other researchers at the BSC and leverage their complementary skills. The researchers will also, together with environmental analysts and communicators, and in collaboration with a broad network of other marine researchers, participate in communication efforts to improve society’s ability to address environmental problems in the Baltic Sea. 

The IceCube Neutrino Observatory at the South Pole, Antarctica, is the world’s largest neutrino telescope, operated by an international collaboration of about 350 scientists in 14 countries. IceCube pursues a broad array of science objectives from particle physics to astronomy. Chief among these is using the weakly-interacting neutrino particle to explore extreme astrophysical environments, complementing observations made with photons. Having first discovered the high-energy astrophysical neutrino flux in 2013, IceCube has now started to associate some of these neutrinos with supermassive black holes in nearby active galaxies, and has made the first observations of the Milky Way galaxy using neutrinos, rather than light. These breakthroughs, together with the first detection of gravitational waves by the LIGO-Virgo detectors, signal that we are entering the era Multi-Messenger Astronomy.

Stockholm University has played a leading role in neutrino astronomy beginning thirty years ago with the AMANDA neutrino telescope at the South Pole. Today the IceCube group is also part of the Oskar Klein Centre for Cosmoparticle Physics, a rich scientific environment that comprises over a hundred researchers working in theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the KTH Royal Institute for Technology.

The position is within the Wallenberg Launch Pad (WALP) Proof-of-Concept (PoC) project TREECURE. The project is funded by the Knut and Alice Wallenberg Foundation. The main goal is to develop 100% bio-based adhesives, completely free from formaldehyde and phenol. Specific objectives include development lignin-based wood adhesive formulations that meet stringent criteria outlined in the industrial standards. Additionally, we aim to create recyclable wood particle-lignin adhesive formulations for extrusion processing and three-dimensional manufacturing.

We are seeking a post-doctoral fellow for 2 years with a broad vision and passion to  develop novel and sustainable  routes to  develop colloidal formulations  based on 2D building blocks and cellulose nanofibers  and assemble the components to control the thermal conductivity in prescribed directions. Scalability of the process will be a priority and processing techniques including coating or 3D printing will be explored. The heat transport flexibility, mechanical properties and robustness in water and organic solvents will be used for performance evaluation. The selected candidate will work in the group of Prof Aji Mathew at MMK.

The Postdoctoral Fellow position is within “Circular lignin materials from well-defined functional building blocks” (CIRCULIG) project. The project is funded by the European Research Council (ERC) and focuses on developing functional materials that are designed for reuse, repurposing, and recycling. The Postdoctoral Fellow will be a key member of the project team, focusing on the development of lignin-based materials based on reversible chemistries. These materials will be designed to possess both functionality and circularity, finding applications in catalysis, electrochemistry, adhesives, and structural materials.

Despite that borosilicate glasses (BS) are exploited in numerous applications from everyday products to nuclear waste encapsulation and biomedical implants, the understanding of their sub-nanometer structure remains limited. In particular, some “exotic” structural motifs, such as directly interlinked BO₄ groups (B^[4]-O-B^[4] linkages) and non-bridging O (NBO) species at BO₄ groups (B^[4]-NBO bonds) are either considered absent or remains largely ignored in current BS glass-structure models. Yet, we have recently shown that B^[4]-O-B^[4] linkages are both inherent and abundant structrual motifs in BS glasses [1,3]. The present postdoctoral project is an extension of our recent research on structure and properties of BS glasses [1-3], where magic-angle-spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy will be utilized for unravelling the borosilicate glass structure across a sub-nanometer scale. Those results will then be analysed in conjunction with measured mechanical and elastic properties of the glasses to establish composition-structure-property relationships. One part of the project also involves the development of new NMR experimental techniques for an improved probing of ¹¹B-¹⁷O connectivities in borate-based glasses.

This project is connected to the group endeavour to develop biodegradable organic bioelectronic devices. The Postdoctoral Fellow will play a central role in the project team, by synthesizing and characterizing organic polymers that combine performance and sustainable design. The new materials will have direct application within the bioelectronic devices developed in the group. Advanced characterization techniques will be used to understand their structure, properties, and performance.

This recruitment is connected to the Wallenberg Initiative Materials Science for Sustainability (WISE, wise-materials.org). WISE, funded by the Knut and Alice Wallenberg Foundation, is the largest-ever investment in materials science in Sweden and will encompass major efforts at Sweden’s foremost universities over the course of 10 years. The vision is a sustainable future through materials science. Read more: https://wise-materials.org

Aerosol particles affect Earth’s climate directly by scattering and absorbing radiation and indirectly by affecting cloud microphysical processes. Currently, rapid changes in anthropogenic aerosol emissions are taking place all over the world, which may influence the micro- and macro-scale characteristics of thunderstorms and extreme rain events in highly uncertain ways. This project aims to improve our understanding of aerosol effects on deep convective storm systems by performing convection-resolving model simulations and comparing the simulations with novel in-situ and remote sensing data.  

The position will be part of the new Horizon Europe project CleanCloud, which aims to understand interactions between clouds and aerosols in various geographic and climatic regions and to improve their representation in numerical climate and weather models to quantify their impact on climate, weather, and society. As a part of CleanCloud, the successful candidate will join a broad international research community consisting of 14 international research teams at the forefront of global climate research.
