Projet SORTIR (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : CLOSED

In recent years, spintronics has seen a substantial increase on application in data storage devices, targeting low-energy cost and non-volatility. Indeed, the magnetic random access memory (MRAM) is the only non-volatile memory capable of high-density, high-endurance and fast-write operation and is considered as the best candidate for embedded non-volatile applications. In this technology, the information is stored by the direction of the magnetization of ferromagnets. The most scalable and efficient way to control the magnetization is the use of spin currents, which exert a torque on it and can fully reverse its direction. The most common spin-sources investigated for spin-orbit-torque MRAM (SOT-MRAM) are heavy metals such as Pt, W or Ta, which convert an electrical current in a spin current by means of, for example, the spin Hall effect arising from their strong spin-orbit coupling. The reported SOT efficiencies indeed allow current-induced magnetization switching, however, the current densities required are still too large for practical implementations.  Steady progress in two-dimensional materials (2DMs) offers new perspectives for downscaling and improving MRAM performance. Their 2D nature and weak van-der-Waals interaction between layers enables to create atomically thin stacks with sharp interfaces, circumventing roughness and inter-diffusion, which significantly degrade the spin properties of conventional materials. Among them, topological insulators and transition metal dichalcogenides are expected to be very efficient spin-sources that could significantly enhance the SOTs in comparison to conventional bulk materials. The SORTIR project therefore aims at using the unique properties of 2DMs to unleash their potential for high SOT efficiencies, targeting both low-consumption and high density for data storage.

Projet ECTOGLOB (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Environment and Geosciences
Statut du projet : SIGNED

General background – Global change is at the centre of the alarming declines of many tetrapod species, especially ectotherms (amphibians and reptiles). To date, however, the demographic processes underlying the global declines of tetrapods as a whole, and ectotherms especially, remain poorly understood, limiting our ability to quantify, predict, and manage extinction risks. Gaps and challenges – Global change factors (climate, habitat degradation) are likely to have major deleterious effects on vital rates such as adult survival, a key parameter in population dynamics and a strong predictor of species extinction risk in endotherms. Yet, our understanding of these processes across tetrapods remains limited, mainly because demographic data on ectotherms have long remained scarce and disparate. Aims of the project – In ECTOGLOB, I will (1) develop the ECTOLIFE web platform, an open-access tool for storing, preserving, and promoting the use of demographic data on amphibians and reptiles; (2) assess how adult survival predicts demographic resilience and extinction risks of tetrapods in general, and ectotherms more specifically; and (3) analyse how the thermoregulatory mode mediates the influence of climate and human footprint on adult survival, expecting more severe impacts in ectotherms. Methods – The project builds on my past research, relying on the ECTOLIFE database that I have developed over the last 8 years. ECTOLIFE compiles longitudinal and transversal data from 1,555 populations of 527 species of amphibians and reptiles worldwide. Using adult survival estimates from ECTOLIFE data and those of endotherms from published studies, I will conduct large-scale comparative analyses, taking advantage of key methods developed by my host and secondment. Projected impacts – ECTOGLOB will shed light on major mortality processes involved in tetrapod biological crises, and will facilitate the development of further international research projects via the ECTOLIFE platform.

Projet TOPOMAX (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : SIGNED

Last year’s discovery of states hosting the fractional quantum Hall effect at zero magnetic field in a lattice system – zero-field fractional Chern insulators (FCIs) – has caused tremendous excitement within the condensed matter community. These zero-field FCIs were first observed – by a team including the applicant – using both optics and transport in a molybdenum ditelluride (MoTe2) moiré superlattice. These states, analogs of the Jain sequence FQH states, host Abelian anyon excitations. However, for certain twist angles, moiré MoTe2 is also predicted to host states with non-Abelian anyons - the main requirement for achieving scalable topologically protected quantum computation. These non-Abelian states have yet to be observed. Perhaps the largest difficulty in moiré systems is sample quality and twist angle control. Contact resistance, strain, twist angle inhomogeneity, bubbles, and polymer residue can preclude the formation and observation of delicate non-Abelian FCIs. The main goal of TOPOMAX is to investigate, using optical and transport measurements, the existence of non-Abelian states at zero magnetic field in ultra-high quality twisted MoTe2 heterostructures. To achieve this, we will implement cutting-edge fabrication techniques that enable unprecedented twist angle control and homogeneity while allowing for devices compatible with optical and transport measurements. In particular, the bent bilayer nanomanipulator technique will enable systematic investigation of zero-field FCIs as a continuous function of twist angle. Determining whether the moiré MoTe2 system hosts non-Abelian states would lay the groundwork for study of zero-field non-Abelian anyons – and perhaps, one day, topologically protected qubits.

Projet QuMaHHARIS (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Chemistry
Statut du projet : SIGNED

This is a multidisciplinary project that combines original organic and inorganic chemical synthesis with advanced electronic resonance spectroscopy to produce the next generation of multifunctional molecular quantum processor prototypes. Quantum technologies will embody the second quantum revolution, bound to change dramatically the landscape of information processing, communications and nanotechnology, thereby bringing profound changes to society. This could be realized through the coherent manipulation of the electronic or nuclear spin degrees of freedom. In this context, the growing importance of spin-bearing molecules as the potential physical platform to realize quantum technologies demands the design and precise characterization of the required molecular components with the appropriate functions. The objective of this proposal is to generate molecular qubits bearing functional components for their implementation. These components will be, a) single ion magnets (SIMs) to engender a local magnetic field for individual qubit operation, b) spin crossover (SCO) centers to provide a mechanism for tuning the qubit quantum coherence using light, c) molecular units exhibiting magnetocaloric effect (MCE) to generate a local mechanism for qubit refrigeration, or d) ancillary qubits to realize multiqubit quantum gates within molecules. A first period at Windsor University (Canada) will be dedicated to the synthesis of hybrid main group radical/coordination chemistry compounds. A six-month secondment at the National High Magnetic Laboratory in Florida (USA) will allow deep characterization of the compounds prepared and quality training in pulsed EPR. The final part at the University of Barcelona (Spain) will consist in incorporating the radical systems produced at Windsor as components of supramolecular assemblies. The last part will allow also advanced characterization with the local pulsed EPR infrastructurQuantum Materials: Harnessing Helicates and Radicals in Synergy

Projet IMPACTRANS (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

This Fellowship will enable me to establish myself as a leading female researcher in indirect translation in modern Japan with expertise in Digital Humanities, and to develop my career by undertaking advanced training, knowledge exchange, dissemination, deepening my expertise. Research training is implemented through the proposed project and in a collaboration with two leading experts. The project investigates the relationship between translators? social statuses and their approaches to producing indirect translations (i.e. translations of translations) in Japan during the Meiji period (1868-1912). The aim of this interdisciplinary project is to lay the ground for a larger collaborative project which I will undertake following this Fellowship. I will spend the preparatory (M1-M3) and return stages (M24-M36) at the School of Languages, Literature and Cultural Studies, Trinity College Dublin (TCD), under the supervision of Dr James Hadley, an expert in Digital Humanities and Japanese Translation. At TCD, I will develop specialist skills in Digital Humanities, mentoring and networking through training, teaching, organising a conference and public engagement which enable me to share my knowledge. During the outgoing stage (M4-M23) I will be hosted by the School of Culture, Media and Society, Waseda University (WUD) Japan, under the supervision of Prof Hirokazu Toeda, a highly established specialist in Modern Japanese Literature. At WUD, I will have full access to extensive archival materials and expert knowledge in Modern Japanese Literary Culture and Gender, which are crucial for this project. I will also collaborate with WUD?s experts in these areas and develop my professional network which I will share at TCD. These facilities and opportunities will greatly assist the development of this project, benefit my personal development as an independent researcher as well as generate collaborative opportunities for future projects for myself and the host institutions.

Projet ARCHIVWAR (Horizon Europe, appel à projets 2021)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

Wartime Syria questions conventional understandings of the archive as a physical repository of documents and set of institutional practices. While Syrian state archives have fallen victim to destruction and plundering, Syrians in the diaspora have been saving and retrieving copies of mundane legal documents originally stored in state repositories as these documents are official proof of legal identities, education and relations to kin. These papers are fundamental in any migratory project since they are needed for numerous procedures, such as getting married. These documents are also central in preserving a connection to family members in Syria and in the diaspora. ARCHIVWAR examines these papers’ ubiquity, so far undetected in the study of the Syrian predicament, and the dislocation of state archives in private repositories to rethink the concept of the archive as a form of care. By examining family archives within the Syrian diaspora in Berlin, the action first aims to capture the modes of care and the relations to affective and physical presences and absences stored in these documents. Second, the project aims to make accessible a collective history-in-the-making about the Syrian predicament in Europe. Built upon the skills and experiences I have acquired along my research path, the action combines ethnographic methods with oral history research while employing an innovative format of engaged public scholarship. The project blends open science practices with immersive collaboration with the research participants to consolidate European society’s scientific literacy on wartime Syria and its long-lasting effects in Europe. ARCHIVWAR aims to contribute to the study of war and migration as well as of the archive and alternative forms of knowledge production, but as well widen my knowledge and skills in the field of Social Anthropology, Migration Studies, curatorship and and open access practices to complete my maturation as an engaged social scientist.

Panel : Chemistry
Statut du projet : SIGNED

This project addresses the pressing need for sustainable and durable concrete infrastructure by investigating the degradation mechanisms of cement paste (the binder phase of concrete) materials at the atomic level. Leveraging advanced atomistic simulations, we will focus on the chemo-poro-mechanical properties of cement paste to provide a fundamental understanding of how environmental factors and material composition influence material degradation processes including freeze-thaw, carbonation, alkali-silica reaction, and accelerated decalcification in saline solution, based on which effective mitigation strategies such as compositional optimisation, molecular structure design, and surface modification will be developed to enhance the long-term durability of cementitious infrastructure, contributing to a reduction in the carbon footprint of the construction industry. The project will employ a multidisciplinary approach combining computational modelling, experimental validation, and material development. The project outcomes will directly contribute to the Work Programme's objectives by: 1. Advancing global scientific knowledge in the field of sustainable construction materials. 2. Developing innovative solutions for enhancing the lifespan of cement-based infrastructure and reducing the environmental impact of the construction industry. 3. Fostering collaboration between academia and industry to accelerate the adoption of sustainable construction practices.  This project will contribute to a more sustainable and resilient built environment by providing the scientific basis for the development of next-generation concrete technologies.

Projet CaveMum (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Life Sciences
Statut du projet : SIGNED

Animal development is initially directed by maternal products deposited in the egg, entirely controlling early embryogenesis, including key patterning events, before the maternal-to-zygotic transition (MZT) and zygotic genome activation. Despite differences in maternal programmes between species, the role of maternal factors in morphological evolution remains largely unexplored.  This project aims to address this question using Astyanax mexicanus – a fish species with sighted river-dwelling (SF) and blind cave-adapted (CF) morphs that have rapidly and extensively diverged in morphology, physiology and behaviour. CF and SF egg transcriptomes display strong maternal signatures linked to differences in gastrulation and cavefish sensory phenotypes. The host laboratory discovered that divergence between maternal programmes primarily involves genes with metabolism-related functions. Thus, variation in embryonic metabolism and processes it influences may constitute an important mechanism of developmental evolution. To address this hypothesis, I propose to first characterise the aspects of metabolism under divergent maternal control to identify candidate genes for functional analysis. Second, I will employ transcriptome editing and chemical treatments to examine the function of the candidate genes in cavefish embryogenesis, and the phenotypic outcomes will be characterised to link metabolic and phenotypic variation. Finally, I will test the hypothesis that morph-specific aspects of embryonic metabolism may influence the timing, dynamics and extent of the essential transcriptome reprogramming event during embryo development – MZT. Altogether, this innovative, timely and highly integrative study will shed new light on the functional importance and mechanisms of maternal control and embryonic metabolism in the phenotypic evolution of cavefish and, more broadly, vertebrates.

Projet HeatSIM (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Environment and Geosciences
Statut du projet : SIGNED

Fractured reservoirs are targets for enhanced geothermal systems (EGS), because a network of fractures in an otherwise solid rock is an optimal pathway for circulating the working fluid while efficiently extracting heat. The main ambition of HeatSIM (Heat Transport - Simulation, Inversion, Measurements) is to increase our comprehension of coupled thermal-hydraulic processes and the resulting heat transfer in fractured rocks over different scales, by experimental imaging, numerical simulation and inverse modeling of lab data. The first work package (WP1) will measure heat transfer in laboratory experiments, focusing on the influence of fracture wall topographies and local fracture apertures, dead-end fractures, fracture network topology, and fracture intersections. To this aim, a novel optical thermometry measurement technique, based on the temperature-dependent fluorescence of phosphor colloids, will provide the evolving temperature field within the fluid domain and solid matrix with high spatial and temporal resolutions. A sensitivity analysis will allow quantifying the influence of the various geometric parameters on the outflow temperature. HeatSIM’s WP2 will then propose conceptual simplifications to the experimental geometries, coupled to numerical simulation to predict outflow temperatures. Different such models will be implemented, and their hydraulic and thermal properties will be calibrated from the experimental thermal breakthrough curves. Their outflow temperature prediction capabilities will also be compared. Thanks to the applicant’s strong background in EGS, numerics and inverse modeling, and the host team’s expertise in fractured media, subsurface heat transport and lab experiments, HeatSIM will thus decipher the impact of fractured media’s geometry on heat transfer efficiency, and provide new insights into the prediction of geothermal sites’ efficiency and the optimization of geothermal energy energy extraction.

Projet CryoYeTi (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

Cryo-Electron Tomography (Cryo-ET) is a powerful technique that allows observing the 3D structure of biological molecules in their native cellular environment, and as such, has a unique promise to transform our understanding of biology at the mesoscopic level. Currently, its full impact is constrained by the difficulties associated with interpreting the 3D tomograms in terms of the molecular reality they represent (the so-called assignment problem), which mainly happens due to low resolution and noise inherent to the method.  Our research goal is to develop innovative and highly efficient computational tools that will help to overcome the existing challenges and help to address the assignment problem. We shall achieve this goal by building invariant representations of 3D volumetric data that will allow us to significantly speed up the processing of tomograms and expand the scale and accuracy of the analysis that can be performed. This mathematical foundation will allow us to strengthen both template-based and template-free approaches to the assignment problem, addressing the critical weaknesses of the current state of the art, specifically, the high computational costs of the former and dependence on scarce training data of the latter. To demonstrate the whole capacity of our approach, we shall apply it to novel tomograms of highly important whole-cell biological samples obtained by our experimental collaborators.  This highly multidisciplinary project (math+computation+biology) rests on the unique theoretical/computational competencies brought by the supervisor and the candidate, and involves a key experimental collaboration, bolstering the exchange of scientific knowledge. The planned training of the candidate in mathematical/algorithmic methods, the peculiarities of the Cryo-ET data, and key transversal skills will strengthen his profile as a specialist in integrative molecular modeling and ensure a successful transition to the next career stage.
