In Europe today disabled people comprise some 65 million (10%). Yet they are marginalized in society and research, and little is known on how disabilities become liveable. This project challenges this bias by proposing to investigate ‘liveable disabilities’ as a function of disability and opportunity structures across time. It analyses four life course dimensions: disabled people’s (1) health and well-being; (2) involvement in education and work; (3) in a partner relationship and family; and (4) in leisure structures. Through this I identify liveable disabilities before, during and after the Swedish welfare state. The results are of significant cross-national interest as they form a useful baseline for what constitutes liveable disabilities, which helps governing bodies maximize opportunity structures for disabled people to participate fully in society. This proposal is unique in employing mixed-methods life course research across time. First, it involves quantitative analysis of Sweden’s long-term digitized population databases, which reflect how disability impacts on people’s educational, occupational, marital and survival chances. The statistical outcome is novel in demonstrating how different impairments intersect with human characteristics relative to society’s structures of the past 200 years. Second, qualitative analyses uncover how disabled people today experience and talk about the above dimensions (1-4) themselves, and how mass media depict them. Third, I make innovative studies of leisure structures, which may promote liveable disabilities. The proposal aims to establish me at the forefront of disability research. It benefits from my scholarship in history and demography and from three excellent centres at Umeå University I am connected to, funded by the Swedish Research Council. One centre researches populations, another gender. The third provides expertise in disability studies and ready access to stakeholders outside academia.

Filoviruses are amongst the most dangerous human pathogens. They pose a great health concern, due to a growing number of emerging species, that vary in tropism and pathogenicity. In my work, I aim at establishing a correlation between filoviruses pathogenicity, the characteristics of their interaction with the cell membrane and their entry and egress potential. In this context, I hypothesize that viral carbohydrates are key in modulating these processes. For this study, I have selected a number of filovirus species, distinct in their pathogenicity for humans. I will use a transcription and replication competent virus like particle system (trVLP) as a BSL-2 virus model, and will produce particles presenting the glycoproteins (GP) from the different filovirus species of interest. GP is the sole glycoprotein found on the virus surface and is crucial for filovirus attachment and entry. Using an interdisciplinary approach combining virology, biophysics and glycobiology, I will first carry out infection assays, to characterize the entry and egress potential of the different particles. I will further investigate the role of two key attachment molecules, heparan sulfate and DC-SIGN in modulating those processes. This will be achieved first on the cellular level, and then on the molecular level, using single molecule force spectroscopy to look at the characteristics of individual ligand-receptor bonds. Extensive glycomic analysis, amongst other via mass spectrometry, will further address the hypothesis that the GPs glycan profile plays a key role in determining the behaviour of the different filoviruses. Taken together, I will provide a comprehensive description of the influence of the different GPs in viral entry and egress, on the molecular, functional, and biological levels. Such insights will without doubt be key to the development of efficient and broad-spectrum antivirals.

Artificial illumination is fundamental and ubiquitous in modern society, and the cuArtificial illumination is fundamental and ubiquitous in modern society, and the current large-scale commercialization of more efficient and practical technologies, in the form of LEDs and OLEDs, is therefore important. This development is not only resulting in improved luminaires and displays, but also paving the way for a wide range of applications in, e.g., medtech, security, and communication. However, a growing concern is related to that the fabrication of LEDs and OLEDs consumes large amounts of critical raw materials (CRMs) and energy, and that their recycling is poorly developed and difficult. A novel illumination technology, the light-emitting electrochemical cell (LEC), is in this context interesting, and we and others have recently developed concepts for its material- and energy-efficient and CRM-free printing fabrication and its delivery of efficient emission (although not yet on par with LED/OLED). These combined achievements now pave the way for a timely and important challenge: can the LEC become the first emissive technology that is truly sustainable through its entire lifecycle? We boldly argue that this vision can turn true if we can take control of the defining LEC feature, viz. the dynamic formation of a p-n junction by electrochemical doping. It was recently shown that current LECs suffer from severe quenching of the excitons (the photon precursors formed in the p-n junction) by too-nearby dopants, and we here introduce new insights and methodologies that address this setback through rational design and careful development of new materials. A key task is to tune the mobility of the electronic charge carriers and excitons, through guidelines established by modeling, for the attainment of a sharp p-n junction boundary. We emphasize that our proposed path to high-efficiency LECs does not depend on energy-intense processes or the use of toxic or CRM-based materials.

Sustainable, recyclable, and low-cost light-emitting technologies are projected to revolutionize the lighting market by introducing new applications in disease treatment, packaging, architecture, and fashion. The light-emitting electrochemical cell (LEC) may become such a disruptive lighting technology. It can be fabricated from biodegradable materials using cost-efficient printing or coating and offers soft areal emission from flexible and thin luminaires. In contrast to established (organic) LEDs, an LEC comprises only one active layer in which an organic semiconductor is blended with an electrolyte. Under operating voltage, the mobile ions redistribute and form self-organized charge-injection and transport regions. While being a promising concept for versatile, next-generation lighting, LECs currently suffer from inadequate operating lifetime and efficiency. Recent data suggest that the same ion redistribution that enables single-layer functionality also induces severe exciton-polaron quenching. This causes a reduction in light emission by about a factor of two and fast material degradation. Building on this new insight, I want to combine the expertise of OPEG, a leading group in LEC research, with my knowledge in optoelectronic characterization and modeling to develop a better understanding and control of the ion redistribution process in LECs. The associated suppression of ion-induced exciton-polaron quenching has the potential to enhance the LEC efficiency and lifetime towards industrial relevance, rendering it a promising next-generation light source.

Previous research has investigated the relationship between unemployment and health from a perspective of an isolated individual. HEALFAM takes a novel approach and examines how transition to unemployment triggers diffusion of ill mental and physical health within families. It investigates how becoming unemployed affects health outcomes of partners, children and elderly parents of the unemployed and whether the magnitudes of these influences differ across families and societies. Thus, instead of viewing the unemployed as functioning in isolation, HEALFAM assesses the consequences of unemployment for family members taking a multi-actor perspective and international comparative approach. Guided by the life course theoretical framework, which views health and well-being as a process rather than a state and calls for considering interrelatedness of individuals, HEALFAM employs longitudinal data that provide information about multiple members of families. In order to analyse these datasets, HEALFAM uses longitudinal dyadic data analysis techniques as well as multilevel models for longitudinal data. HEALFAM aims to open a new frontline of research on health and wellbeing from a life course perspective. It benefits from my knowledge on three interrelated social phenomena: (1) the role of labour market career and experiences of unemployment (2) family structure and intra-family resources (3) social antecedents of health and wellbeing among family members. It draws on high quality register and panel survey data as well as the expertise at the interdisciplinary research centres that I am connected to at Umeå University. Through international collaborations, it brings together experts in multiple disciplines carrying out research taking a life course perspective.
