Projet DIRACFEC (Horizon Europe, appel à projets 2022)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : SIGNED

In our modernized era, beyond-5G and 6G wireless systems will be key to satisfying crucial society demands. The new challenging 6G KPI, the renewed need for sustainable and green networks, and the introduction of AI and sensing, evinces the necessity of incorporating new technologies and of designing novel solutions. In that sense, cell-free massive MIMO, reconfigurable intelligent surfaces (RISs), and edge intelligence are anticipated to be key technologies in the 6G era. DIRACFEC is a 24-months research project that thus concentrates on the Design of Intelligent RIS-Aided Cell-Free networks for Energy-efficient Coexistence between evolved eMBB (eMBB+) and evolved mMTC (mMTC+). More specifically, considering user-centric architectures and distributed multiple antenna deployments, we will present a set of multiple access schemes, edge intelligence techniques, and transmission strategies that optimize the energy efficiency in a heterogeneous service environment, aiming at the coexistence of eMBB+ and mMTC+ services. We will conceive mathematical frameworks to model dense networks where several RISs are controlled by multiple antenna access points. Then, to boost the ultimate performance, we will design the aforementioned approaches for different types of data traffic under the assumption of imperfect channel knowledge. These solutions will be evaluated using numerical and industry level system-level simulations in practical setups.  The project will be carried out by the researcher at the University of Cassino and Lazio Meridionale (Italy), under the supervision of Prof. Stefano Buzzi. Furthermore, Nokia Bell Labs (France) will host the researcher for a six-months secondment aimed at validation of the developed solutions on industry level system simulators. The applying researcher is Dr. Sergi Liesegang, a fresh PhD graduate from the Politechnic University of Barcelona (Spain).

Projet LETITIA (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : TERMINATED

The acquisition of turn-taking is pivotal to a child's pragmatic development; learning how and when to contribute and align with your interlocutor is a critical skill that enables smooth conversation. Despite extensive research on the development of turn-taking in spoken languages, we know little about how this unfolds in sign languages. Differences are likely as deaf children usually lack rich language models (ecology), and the visual-spatial nature of sign languages poses different challenges to manage visual attention (modality). To address this gap, this project investigates turn-taking development in an exceptional context: a Balinese village characterized by high incidence of deafness and widespread use of the local sign language, Kata Kolok. Here, children acquire Kata Kolok surrounded by a village of signing adults, providing an unparalleled opportunity to study how signing-rich ecologies shape turn-taking development in the visuo-spatial modality. I conduct two complementary studies: First, I follow the developmental trajectory of turn-taking of deaf children across 1-4 years, comparing their practices to turn-taking practices used by the adult signers in their community. For this, I draw on a unique interactive corpus of longitudinal naturalistic recordings of children who acquire Kata Kolok from their deaf caregivers from birth (KKCSC) and use a micro-level analysis of spontaneous conversations. Second, I use an experimental spot-the-difference task to further tease apart how conversational setting affects turn-taking, examining whether age of conversation partners (child vs adult) and number of interlocutors (two vs three or more) affect turn-taking behaviour among adult and child Kata Kolok signers. Merging threads from social interaction, sign language linguistics and language acquisition, the LETITIA project represents a paradigm shift in the study of sign language acquisition, grounding linguistic observations and analyses in real-world language use.

Projet CryArctic (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Environment and Geosciences
Statut du projet : SIGNED

The rapid climate warming in Arctic leads to formation of extensive offshore groundwater reserves through submarine permafrost and subglacial melt water drainage. There is increasing evidence that cryosphere driven submarine groundwater discharge (SGD) is prevalent in continental shelf and slope regions of Arctic Ocean, but controls of elemental fluxes through SGD remains uncertain. The CryArctic project closely investigates how cryosphere driven groundwater flow, occuring in timescales from days to millennium, interacts with the permeable sediments (silicates and carbonates) in coastal aquifers and seafloor. The solute delivery and associated source/sinks of submarine groundwater flow remains unknown and are gaps in our current understanding of Earth’s cryosphere and biogeochemical cycling. The project aims to provide elemental and isotopic composition of submarine groundwater endmember through extensive analysis of marine porewater from six locations pan-Arctic where SGD is documented. Through state-of-the-art silicon (Si) and strontium (Sr) isotopic measurements of marine porewater, terrestrial endmembers and other leached fractions we will be able to decipher dominant biogeochemical process occuring within the subterranean mixing zones. We supplement the high resolution isotopic measurements with scanning electron microscopy and X-ray diffraction to identify major authigenic and detrital phases in sediments. The project will be the first to couple Si and Sr isotopes in marine porewater and results will have implications for solute delivery through SGD and silicate alteration pathways in marine sediments. Through MSCA fellowship, candidate aim to acquire skills for long term research planning, advanced instrumental training, form international collaborative networks, and most importantly gather the attention of scientific community as well as public towards the magnitude and relevance of Arctic SGD.

Projet PON-SXT (Horizon Europe, appel à projets 2023)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Environment and Geosciences
Statut du projet : SIGNED

Dr. Sara Santiago Malagón will conduct a fellowship focused on developing a Lab-on-a-Chip (LOC) colorimetric paper-based device for point-of-need (PON) detection of saxitoxin, a toxin produced by cyanobacteria and certain microalgae. The primary objective of this project is to mitigate cyanobacteria contamination in stagnant water and harmful algae bloom (HAB) occurrences in seawater, which can lead to the death of marine species and the poisoning of animals and humans. We aim to validate an accessible, eco-friendly, cost-effective, and user-friendly technology that can be extended to detect and quantify various biotoxins relevant to public health and the environment. The driving force behind this project is the current gap in the development of portable sensor systems for environmental applications in marine ecosystems, freshwater, and seafood quality control, all without the need for specialized equipment.  In addition to the research that will help control and prevent damage to the ecosystem and preserve species diversity, the methodology and materials presented are sustainable and environmentally friendly, aligning with the project's environmental commitment. Furthermore, the materials used (silk) will facilitate the stabilization of biomacromolecules required for the detection and quantification of saxitoxin, enabling the creation of long-span sensors. Ultimately, the end goal is to validate that the colorimetric device, designed as a toolless system, can be operated by minimally trained volunteers (end users) through a user-friendly mobile application interface, even if they do not possess specialized knowledge or skills. These individuals play a crucial role in environmental preservation and prevention efforts.  This grant would offer the applicant the opportunity to lead an international project, fostering collaborations with esteemed institutions and researchers for future global initiatives.

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

Sustainable groundwater management is one of the defining societal challenges under rapid global change. But in many Small Island Developing States (SIDS), effective resource management is complicated by a lack of comprehensive groundwater assessments and an inherent susceptibility to natural and anthropogenic pressures on water quantity and quality. The limited understanding of present-day groundwater dynamics in SIDS is only matched by our insufficient knowledge of past global change in oceanic regions. These combined challenges preclude confident climate predictions and mitigation measures.  To address critical knowledge gaps relevant to local resource managers, and extend the sparse South Pacific palaeoclimate record beyond the instrumental period, my project GROTTOS ('GROundwater and climate Through Time – modern Observations and Stalagmite-based recharge estimates on a raised coral atoll') seeks to refine the quantitative understanding of groundwater recharge and its climate drivers on the South Pacific carbonate island of Niue (ca. 19°03′14″S, 169°55′12″W). Taking advantage of the tropical karst geology, GROTTOS firstly aims to provide a holistic assessment of Niue’s present-day recharge dynamics by the novel integration of conventional groundwater monitoring with observations from soil and caves in the unsaturated zone. Aligned with local priorities, groundwater will further be analysed against international quality standards and for the first time tested for major synthetic pollutants. Finally, we aim to apply a newly developed quantitative geochemical proxy for past cave drip rates to several Holocene Niuean stalagmites. With insights from modern observations, this will shed new light on South Pacific climate variability and its effect on groundwater recharge through time.

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

Dandelions (Taraxacum agg.) are one of the most important plants for insects, providing up to 80% of early spring pollen production in meadows. This high pollen production is surprising and unfavourable from the plant’s perspective as most dandelions reproduce asexually (apomixis). Decreased selection on nutritious pollen is therefore expected and would lead to lower production and degenerate (poor) pollen, or even complete male sterility, in the absence of sex. This would have potentially disastrous consequences for the dependent insects, especially in areas of higher latitude (e.g. Sweden) where sexual dandelions are absent. Little is known, however, about the evolutionary effects of asexuality on pollen production, particularly from a genomic point-of-view. We aim to understand how pollen degenerates under asexuality through a combination of phenotypic and genotypic characterisations in sexual and asexual dandelions, including male sterile plants: 1) microscopy and flow cytometry will reveal the effect of asexuality on pollen number, morphology and viability; 2) comparative transcriptomics in pollen, petals, bracts and leaves will reveal pollen-specific genes and if they are down-regulated under asexuality; 3) comparative transcriptomics in anthers will reveal genes necessary for healthy pollen production; 4) comparative genomics using full gene sequences will reveal the rate of deleterious mutation accumulation in pollen-specific genes, for which museum specimens will be unlocked using a customised Hyb-Seq approach. The fellow will fill significant skill gaps in their career through training in gene expression studies, whilst establishing themselves in plant reproductive biology. NoSexPoorPollen will be the first study to compare pollen gene expression in sexual and asexual plants. By combining phenotypic and genomic studies on pollen under asexuality, we provide an impactful and clear indication of the amount of insect food lost in the absence of dandelion sex.

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

The rising CO2 emission has underscored the need for innovative approaches toward CO2 management. Li-CO2 batteries provide a promising strategy for direct CO2 fixation in energy storage devices with a high theoretical specific energy of 1876 Wh/kg, highlighting in effective CO2 management. A key challenge in Li-CO2 batteries is that the sluggish CO2 conversion including CO2 reduction reaction (CRR) and evolution reaction (CER) in cathode seriously deteriorates battery performance. In this project, we propose an integrated cathode design with combined pre-activator molecules and bidirectional atomic catalytic materials in cathode for improving CO2 conversion efficiency. Poly(ionic liquid)s (PILs) with high CO2 affinity, good compatibility to lithium salt and wide electrochemical window, are designed with amine groups as pre-activators in cathode for achieving CO2 activation before electroreduction on catalysts. The diatomic catalysts (DACs) with highly active dual metal centres and theoretical 100% atom utilization, are screened out as bidirectional catalysts for improving CRR/CER simultaneously. Such PILs-modified DACs will be 3D printed into self-supporting integrated cathode with designed open channels and interconnected conductive skeleton, to grant enough solid products support and effective transportation of CO2, Li ion and electron in cathode. Consequently, Li-CO2 batteries with long cycle life (over 1000 cycles) and high energy density (500 Wh/kg or above) will be targeted. In combination with in situ electrochemical characterizations and DFT calculations, mechanism of CO2 conversion in designed cathode will be clarified in this project. Results from this project will inspire cathode design of Li-CO2 batteries on pre-activator and catalytic conversion beyond direct electroreduction on catalysts. It will broaden the perspective on atomically dispersed catalysts and promote the development of energy storage devices accompanied by CO2 utilization.

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

Anthropogenic disturbances in aquatic environments are causing carbon cycle imbalance and eutrophication. Bacteria perform crucial roles in the seasonal succession of aquatic communities and play a key role in the transfer of dissolved organic carbon to the upper trophic levels through the microbial loop. Aerobic anoxygenic phototrophic (AAP) bacteria harvest energy from light through bacteriochlorophyll reaction centers to supply their heterotrophic metabolism. AAP bacteria undergo large seasonal oscillations in abundance and community composition and are linked to phytoplankton bloom in freshwaters, reaching up to 20-30% of total bacterial community during their peaks. AAP use dissolved organic matter released by phytoplankton bloom, and since they have larger size and are under higher grazing pressure, critically participate in the microbial loop. AAP community is driven by the availability of carbon and phosphorus, elements that condition the lake’s trophic status. The aim of this project is to study how eutrophication is changing the fluxes of carbon that AAP bacteria drive in the environment through respiration and carbon assimilation. Environmental dark and infrared (IR) microbial respiration measurements will decipher the impact that photoheterotrophy has on microbial respiration in different trophic status lakes. Additionally, a novel combination of IR-epifluorescence microscopy with NanoSIMS analysis is proposed to quantify the phytoplankton derived carbon assimilation rates by AAP bacteria in different trophic status lakes. Finally, a unique monthly, 12-years long metagenomic and environmental survey from 4 different trophic status lakes (oligotrophic to eutrophic) will decipher the how the eutrophication is changing the AAP community composition and their genetic repertoire, aiding in the adequate management and restoration of eutrophic environments by providing information about the microbial community changes driven by eutrophication.

Projet SyedArcGen (Horizon Europe, appel à projets 2024)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

The transition from Roman to Byzantine rule in Anatolia brought significant sociopolitical and cultural transformations, particularly in coastal cities such as Syedra, located on the southern coast of modern-day Turkiye. Syedra prospered as a thriving urban centre during the Roman era and retained its importance under Byzantine rule. However, despite extensive archaeological research, the impact of this transition on the Syedra community hitherto has not been explored through archaeogenomics.  To address this gap, I aim to conduct an archaeogenomic study of human remains from Syedra, spanning the Roman and Byzantine periods. By generating and analysing ancient genomic data, I will investigate the impact of this transition on the population dynamics, health status, and social structure of the Syedra community.  By integrating archaeogenomic methods with interdisciplinary datasets and leveraging an international network of collaborations, this research will offer a comprehensive understanding of the Syedra community during the Roman-Byzantine transition. As the first study to focus on an Anatolian coastal community during this pivotal period, it will be of great importance and will also provide novel insights into the broader eastern Mediterranean.  Combining my solid track record in ancient human genomics, and the host institution’s expertise in ancient DNA and metagenomics, this fellowship will enable me to develop the key skills to establish myself as a research leader in archaeogenomics and make significant contributions to the field.
