    'home renovation energy savings platform',
    'Leveraging on the business operations of consortium partners (4000 integrated building renovations conducted to date), TURNKEY RETROFIT will develop and replicate an integrated home renovation service which will be initially operated in 3 EU countries - France, Ireland and Spain - with an expected 335M€ investment pipeline for home renovation within the first 5 years (approximately 14 700 dwellings renovated, leading to 96,6 GWh/year Primary energy savings triggered) beyond the end of the project. The project will point to further replication across Europe and Internationally in particular via the Green Building Council network.The TURNKEY RETROFIT service will be developed as a home-owner-centric renovation journey, which will transform the complex and fragmented renovation process into a simple, straightforward and attractive process for the home-owner. It will include the initial technical and behavioural diagnosis, technical offer, contract development and agreement, structuring and provision of financial support, as well as the on-site coordination of works and quality assurance. It will be a service-oriented model where the home-owner is offered tailor-made solutions through the whole customer journey.The service will be accessible through a user-friendly digital platform and it will address drivers of building renovation that go beyond a desire to reduce energy bills and increase asset value, such as home improvement, increased comfort, enhanced health & quality of life.',
    'BLAZE aims at developing Low cost, Advanced and Zero Emission first-of-a-kind small-to-medium Biomass CHP. This aim is reached by developing bubbling fluidised bed technology integrating high temperature cleaning & conditioning system (IBFBG, that can convert heterogeneous feedstocks in a syngas with zero particulate matter and ultra-low tar and contaminants content), an integrated high temperature gas cleaning approach for HCl and H2S removal and an innovative key component for thermal and chemical integration of solid oxide fuel cell (efficient gas recirculation of the fuel cell anode exhaust to the gasification process via a steam-driven high speed micro-compressor using gas bearing technology). The technology is developed for a CHP capacity range from small (25-100 kWe) to medium (0.1-5 MWe) scale and is characterised by the widest fuel spectrum applicable (forest, agricultural, industrial and municipal waste also with high moisture, ash and contaminants content), high efficiencies (50% electrical versus the actual 20%), low investment (< 4 k€/kWe) and operation (≈ 0.05 €/kWh) costs as well as almost zero gaseous and PM emissions, projecting electricity production cost below 0.10 €/kWh . Gasification, gas cleaning & conditioning and fuel cells will be tested at lab scale and 25 kWe SOFC will be thermally and chemically integrated in 100 kWth IBFBG demonstrating the achievement of new milestones, increasing competitiveness of European industry, energy system reliability and flexibility and biomass plants social acceptance. Process simulations, computer aided design, tests, performance evaluation, risk and safety analysis as well as a technology assessment part covering techno-economic, environmental and overall impact assessments and market studies will be carried out together with a clear dissemination, exploitation and communication plan, that can count on the involvement of the main gasifier, gas conditioning and SOFC European companies and research centres.',

  identify neural markers of partner action prediction in joint turn-taking tasks	The ability to perform joint (multi-person) actions such as ensemble music performance confers numerous benefits, from generating unique aesthetic experiences to enhancing affiliation with one’s co-actors. Co-actors must be able to accurately predict when one another’s actions will occur so that they can time their own actions accordingly. One question facing the field of social neuroscience is how co-actors learn to make accurate predictions about one another’s actions. The current project, JAL, launches one of the first systematic investigations of joint action learning to address this question on the levels of both brain and behaviour. The project will implement a series of empirical studies in which partners learn novel joint turn-taking tasks while electroencephalography (EEG) is simultaneously measured from both partners: Turn-taking tasks are optimal for measuring prediction processes because partners must be able to accurately predict when one another’s turns will end so that ...
  measure intergalactic magnetic field strength topology with Jansky VLA observations	There is a pressing need to chart the origin, evolution, and impact of magnetic fields over the full 13.7 billion year history of the Universe, with implications for particle physics, cosmology, and astrophysics. Key to this endeavour is a detailed physical understanding of how galaxies have become magnetised and what role intergalactic magnetic fields play in shaping the Universe. To make progress, we need to observationally characterize properties such as the strengths and topologies of galactic and intergalactic magnetic fields. I propose a portfolio of ground-breaking research projects that will capitalise on the recently upgraded Jansky VLA radio telescope to provide new observational measurements of interstellar and intergalactic magnetic fields and elucidate their roles in shaping the Universe. A Marie Skłodowska-Curie Actions Research Fellowship will facilitate movement from my current position as an Assistant Scientist at the National Radio Astronomy Observatory in the USA to ...
  identify mechanisms for building cross-cultural peace in frontier societies after European expansion	This research project investigates the historical roots of cross-cultural peacebuilding. European expansion during the sixteenth century was characterised by a high degree of violence, which was fuelled by cultural differences and religious radicalisms. The meeting of different cultures created new forms of violence, but, at the same time, generated new forms of cross-cultural encounters that were driven to construct a lasting peace. This project explains the transition from the violent conflicts of the first encounters between Europeans and non-European peoples, to their peaceful coexistence. Rather than focusing on cross-cultural diplomacy or treaty-making, this research project explains how peace was constructed “on the ground”. In order to do so, it focuses on three different frontiers of the first global empires. Through a comparative survey that includes cases from the Mediterranean, the Americas and Asia, this project shows that frontier societies resulting from European expansi...
