Run away, sidestep, duck-and-cover, watch: when under threat, humans immediately choreograph a large repertoire of defensive actions. Understanding action-selection under threat is important for anybody wanting to explain why anxiety disorders imply some of these behaviours in harmless situations. Current concepts of human defensive behaviour are largely derived from rodent research and focus on a small number of broad, cross-species, action tendencies. This is likely to underestimate the complexity of the underlying action-selection mechanisms. This research programme will take decisive steps to understand these psychological mechanisms and elucidate their neural implementation. To elicit threat-related action in the laboratory, I will use virtual reality computer games with full body motion, and track actions with motion-capture technology. Based on a cognitive-computational framework, I will systematically characterise the space of actions under threat, investigate the psychological mechanisms by which actions are selected in different scenarios, and describe them with computational algorithms that allow quantitative predictions. To independently verify their neural implementation, I will use wearable magnetoencephalography (MEG) in freely moving subjects. This proposal fills a lacuna between defence system concepts based on rodent research, emotion psychology, and clinical accounts of anxiety disorders. By combining a stringent experimental approach with the formalism of cognitive-computational psychology, it furnishes a unique opportunity to understand the mechanisms of action-selection under threat, and how these are distinct from more general-purpose action-selection systems. Beyond its immediate scope, the proposal has a potential to lead to a better understanding of anxiety disorders, and to pave the way towards improved diagnostics and therapies.

Carbon dioxide capture and storage is a technology to mitigate climate change by removing CO2 from flue gas streams or the atmosphere and storing it in geological formations. While CO2 removal from natural gas by amine scrubbing is implemented on the large scale, the cost of such process is currently prohibitively expensive. Inexpensive alkali earth metal oxides (MgO and CaO) feature high theoretical CO2 uptakes, but suffer from poor cyclic stability and slow kinetics. Yet, the key objective of recent research on alkali earth metal oxide based CO2 sorbents has been the processing of inexpensive, naturally occurring CO2 sorbents, notably limestone and dolomite, to stabilize their modest CO2 uptake and to establish re-activation methods through engineering approaches. While this research demonstrated a landmark Megawatt (MW) scale viability of the process, our fundamental understanding of the underlying CO2 capture, regeneration and deactivation pathways did not improve. The latter knowledge is, however, vital for the rational design of improved, yet practical CaO and MgO sorbents. Hence this proposal is concerned with obtaining an understanding of the underlying mechanisms that control the ability of an alkali metal oxide to capture a large quantity of CO2 with a high rate, to regenerate and to operate with high cyclic stability. Achieving these aims relies on the ability to fabricate model structures and to characterize in great detail their surface chemistry, morphology, chemical composition and changes therein under reactive conditions. This makes the development of operando and in situ characterization tools an essential prerequisite. Advances in these areas shall allow achieving the overall goal of this project, viz. to formulate a roadmap to fabricate improved CO2 sorbents through their precisely engineered structure, composition and morphology.

Since the invention of the spinning frame, automation has been one of the drivers of economic growth. Yet, workers, economist or the general public have been concerned that automation may destroy jobs or create inequality. This concern is particularly prevalent today with the sustained rise in economic inequality and fast technological progress in IT, robotics or self-driving cars. The empirical literature has showed the impact of automation on income distribution. Yet, the level of wages itself should also affect the incentives to undertake automation innovations. Understanding this feedback is key to assess the long-term effect of policies. My project aims to provide the first quantitative account of the two-way relationship between automation and the income distribution. It is articulated around three parts. First, I will use patent data to study empirically the causal effect of wages on automation innovations. To do so, I will build firm-level variation in the wages of the customers of innovating firms by exploiting variations in firms’ exposure to international markets. Second, I will study empirically the causal effect of automation innovations on wages. There, I will focus on local labour market and use the patent data to build exogenous variations in local knowledge. Third, I will calibrate an endogenous growth model with firm dynamics and automation using Danish firm-level data. The model will replicate stylized facts on the labour share distribution across firms. It will be used to compute the contribution of automation to economic growth or the decline of the labour share. Moreover, as a whole, the project will use two different methods (regression analysis and calibrated model) and two different types of data, to answer questions of crucial policy importance such as: Taking into account the response of automation, what are the long-term effects on wages of an increase in the minimum wage, a reduction in labour costs, or a robot tax?

What makes for a valuable and good life is a question that many people in the contemporary world ask themselves, yet it is one that social science research has seldom addressed. Only recently have scholars started undertaking inductive comparative research on different notions of the ‘good life’, highlighting socio-cultural variations and calling for a better understanding of the different imaginaries, aspirations and values that guide people in their quest for better living conditions. Research is still lacking, however, on how people themselves evaluate, compare, and put into perspective different visions of good living and their socio-cultural anchorage. This project addresses such questions from an anthropological perspective, proposing an innovative study of how ideals of the good life are articulated, (re)assessed, and related to specific places and contexts as a result of the experience of crisis and migration. The case studies chosen to operationalize these lines of enquiry focus on the phenomenon of return migration, and consist in an analysis of the imaginaries and experience of return by Ecuadorian and Cuban men and women who migrated to Spain, are dissatisfied with their life there, and envisage/carry out the project of going back to their countries of origin (Ecuador and Cuba respectively). The project’s ambition is to bring together and contribute to three main scholarly areas of enquiry: 1) the study of morality, ethics and what counts as ‘good life’, 2) the study of the field of economic practice, its definition, value regimes, and ‘crises’, and 3) the study of migratory aspirations, projects, and trajectories. A multi-sited endeavour, the research is designed in three subprojects carried out in Spain (PhD student), Ecuador (Post-Doc), and Cuba (PI), in which ethnographic methods will be used to provide the first empirically grounded study of the links between notions and experiences of crisis, return migration, and the (re)assessment of good living.

This interdisciplinary proposal has the objective to greatly enhance our understanding of fundamental biomineralization processes involved in the formation of calcium carbonates by marine organisms, such as corals, foraminifera and bivalves, in order to better understand vital effects. This is essential to the application of these carbonates as proxies for global (paleo-) environmental change. The core of the proposal is an experimental capability that I have pioneered during 2008: Dynamic stable isotopic labeling during formation of carbonate skeletons, tests, and shells, combined with NanoSIMS imaging. The NanoSIMS ion microprobe is a state-of-the-art analytical technology that allows precise elemental and isotopic imaging with a spatial resolution of ~100 nanometers. NanoSIMS imaging of the isotopic label(s) in the resulting biocarbonates and in associated cell-structures will be used to uncover cellular-level transport processes, timescales of formation of different biocarbonate components, as well as trace-elemental and isotopic fractionations. This will uncover the origin of vital effects. With this proposal, I establish a new scientific frontier and guarantee European leadership. The technical and scientific developments resulting from this work are broadly applicable and will radically change scientific ideas about marine carbonate biomineralization and compositional vital effects.

"Atmospheric aerosol particles have been shown to impact the earth's climate because they scatter and absorb solar radiation (direct effect) and because they can modify the microphysical properties of clouds by acting as cloud condensation nuclei or ice nuclei (indirect effects). Radiative forcing by anthropogenic aerosols remains poorly quantified, thus leading to considerable uncertainty in our understanding of the earth’s climate response to the radiative forcing by greenhouse gases. Black carbon (BC), mostly emitted by anthropogenic combustion processes and biomass burning, is an important component of atmospheric aerosols. Estimates show that BC may be the second strongest contributor (after CO2) to global warming. Adverse health effects due to particulate air pollution have also been associated with traffic-related BC particles. These climate and health effects brought BC emission reductions into the political focus of possible mitigation strategies with immediate and multiple benefits for human well-being. Laboratory experiments aim at the physical and chemical characterisation of BC emissions from diesel engines and biomass burning under controlled conditions. A mobile laboratory equipped with state-of-the-art aerosol sensors will be used to determine the contribution of different BC sources to atmospheric BC loadings, and to investigate the evolution of the relevant BC properties with atmospheric aging during transport from sources to remote areas. The interactions of BC particles with clouds as a function of BC properties will be investigated with in-situ measurements by operating quantitative single particle instruments behind a novel sampling inlet, which makes selective sampling of interstitial, cloud droplet residual or ice crystal residual particles possible. Above experimental studies aim at improving our understanding of BC’s atmospheric life cycle and will be used in model simulations for quantitatively assessing the atmospheric impacts of BC."

While the crisis of the territorial nation-state in the Middle East has once again been brought to a head by the wars in Iraq and Syria, it cannot be simply understood as the logical consequence of an imported political construction. Based on two epistemological notions – borderlands as histoire-problème (history-as-problem) and the co-production of borders between state and society – this research project proposes to rethink the classical historical narrative about the emergence of the post-Ottoman Middle East. Taking its cue from trans-border phenomena and thus paying attention to the circulation of people, goods and ideas as well as to everyday encounters between local actors and state representatives, the project will be guided by four principle objectives to offer: • A socio-historical analysis of state violence in the borderlands of the Middle East; • An examination of the capacity of border populations to create the history of the borderlands, nation-states, and the region as a whole; • A study of the frontier effects based around the notions of subjectivity, space and time, and involving various levels of observation (macro, meso and micro) in order to identify the ruptures and continuities evoked by the delineation of new borderlines; and • A historical lens through which to make sense of current events in Syria and Iraq, and possibly orient conflict-resolution practitioners. Through the exploitation of a wide range of sources (diplomatic, administrative and military records, missionary documents, newspapers) and by looking at the social construction of international frontiers at the borderlands located between Turkey, Iraq and Syria in the interwar era, the research project will provide a much more holistic yet finely-grained understanding of the formation of the territorial state in the region in the aftermath of the First World War as well as a historical perspective on the on-going armed conflicts.

The demand for donated organs vastly outnumbers the supply, leading each year to the death of thousands of people and the suffering of millions more. Engineered tissues and organs following Tissue Engineering approaches are a possible solution to this problem. However, a prevascularization solution to irrigate complex engineered tissues and assure their survival after transplantation is currently elusive. In the human body, complex organs and tissues irrigation is achieved by a network of blood vessels termed capillary bed which suggests such a structure is needed in engineered tissues. Previous approaches to engineer capillary beds reached different levels of success but none yielded a fully functional one due to the inability in simultaneously addressing key elements such as correct angiogenic cell populations, a suitable matrix and dynamic conditions that mimic blood flow. CapBed aims at proposing a new technology to fabricate in vitro capillary beds that include a vascular axis that can be anastomosed with a patient circulation. Such capillary beds could be used as prime tools to prevascularize in vitro engineered tissues and provide fast perfusion of those after transplantation to a patient. Cutting edge techniques will be for the first time integrated in a disruptive approach to address the requirements listed above. Angiogenic cell sheets of human Adipose-derived Stromal Vascular fraction cells will provide the cell populations that integrate the capillaries and manage its intricate formation, as well as the collagen required to build the matrix that will hold the capillary beds. Innovative fabrication technologies such as 3D printing and laser photoablation will be used for the fabrication of the micropatterned matrix that will allow fluid flow through microfluidics. The resulting functional capillary beds can be used with virtually every tissue engineering strategy rendering the proposed strategy with massive economical, scientific and medical potential

The possibility of having a unique device that converts thermal and photonics energy into electrical energy and simultaneously stores it, is something dreamed by the PI since the beginning of her research career. To achieve that goal, this project aims to gather, in a single substrate, solar cells with up-conversion nanoparticles, thermoelectrics and graphene super-capacitor, all made of thin films. These three main components will be developed separately and integrated sequentially. The innovation proposed is not limited to the integration of components, but rely in ground-breaking concepts: 1) thermoelectric elements based on thin film (TE-TF) oxides; 2) plasmonic nanoparticles for up conversion of near infrared radiation to visible emission in solar cells; 3) graphene super-capacitors; 4) integration and optimization of all components in a single CapTherPV device. This ambitious project will bring new insights at large area, low cost and flexible energy harvesting and comes from an old idea of combining energy conversion and storage that has been pursued by the PI. She started her career in amorphous silicon thin film solar cells, later she started the development of thin film batteries and more recently started a research line in thermoelectric films. If approved, this project will give financial support to consolidate the research being carried out and will give independence to the PI in terms of resources and creative think. More importantly, will facilitate the concretization of the dream that has been pursued with hard work.
