Projet SELEs (Horizon 2020, appel à projets 2017)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Mathematics
Statut du projet : CLOSED

The objective of the research proposed in this project is to give a sound mathematical description of the noise-induced Fréedericksz transition in Nematic Liquid Crystal (NLC) with general geometry configurations. To this aim we will: 1) solve some important and difficult open mathematical problems related to the stochastic stochasic Ericksen-Leslie Equations (SELEs) which basically describe the dynamics of liquid crystals with stochastic perturbations, and 2) give a rigorous mathematical proof of the noise-induced Fréedericksz transition in NLC. In particular, we will establish the existence and uniqueness solution of the Ginzburg-Landau (GL) approximation of SELEs. By using Large Deviations Principle (LDP) theory and the de Giorgi Gamma-convergence we will prove that the action functional of the SELEs with small spatially converges to the action functional of the SELEs with spatially white noise. We will rigorously justify the probabilistic interpretation of the results in terms of the asymptotics of the mean exit time from a neighbourhood of an attracting stationary solution, a hint to noise-induced Fréedericksz transition. By using again LDP theory will rigorously show that in the presence of small noise there is a positive probability of transition between the attraction domains of the stationary solutions for the deterministic system; this is a rigorous mathematical proof of the noise-induced Freédricks’s transition. We will also prove the existence and uniqueness of an invariant measure which satisfies a LDP. The latter result confirms that in the long run the noise still induces transition between equilibria. Finally, we aim to prove the existence and uniqueness of solution of the SELEs, and if time permits transfer results obtained for the GL approximation of SELES to the original SELEs.

Projet cSiOnGlass (Horizon 2020, appel à projets 2014)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Information Science and Engineering
Statut du projet : CLOSED

The objective of this project is the development of high quality poly silicon (poly-Si) thin films on glass applying liquid-phase crystallization by line focus laser irradiation. Introducing an adequate interface layer between the glass and the silicon film and applying laser crystallization by scanning over thin amorphous or nano-crystalline silicon thin films on glass has been shown to yield high-quality poly-Si films for solar cells. These films on glass present also high potential for other electronic devices like e.g. flat panel displays. In photovoltaic (PV) application this technology could result in significant silicon material savings and therefore cost reduction of PV modules in the near future. In the electronic industry it could give new possibilities to fabricate highly integrated electronic circuits on large area. In the frame of this project the investigation and optimization of the laser crystallization process and the design of the interface layer either for low cost soda-lime float glass or ultra-thin high temperature glass will be a focus. Solar cells and mini modules will be fabricated with the aim to develop on the one hand a process technology for large area monolithic integrated poly-Si thin film modules and on the other hand low cost wafer equivalents for back contacted solar cells which on the long-term can achieve efficiencies of multi-crystalline wafer cells. For characterization and analysis of the electronic and optical properties of the glass/poly-Si substrates and solar cells injection level dependent photoluminescence and spectral response measurements will be further developed and implemented.

Projet Road Diplomacy (Horizon 2020, appel à projets 2016)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : CLOSED

The objective of this project is to understand where, why, and to what extent roads are being built between China and South Asia and to untangle the inter-related geopolitical and social impacts of infrastructure development at village, national, and international scales. The project will first map road developments throughout the trans-Himalaya and second investigate the geopolitical drivers and social impacts of road construction. By combining innovative methods from geography, anthropology, and international relations, I will produce new empirical data on infrastructure development in 21st century Asia and illustrate the links between macro geopolitical processes and micro local experiences. Datasets will improve interdisciplinary communications for social scientists and between development practitioners, donor agencies, policymakers, and local stakeholders. The research is of relevance to EU citizens because understanding contemporary dynamics between rising powers like China and India provides context on 21st century global politics and will inform decision-making for EU investment and development interventions in Asia.

Projet SUMAC (Horizon 2020, appel à projets 2018)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : CLOSED

The origin of high-temperature (high-T) superconductivity (SC) is one of the greatest unsolved problems in physics. The solution could potentially lead to room temperature SC with immense technological benefits. There is ample evidence that microscopic magnetic correlations and dynamics are coupled to high-T SC, but a true understanding remains. The proposed research focusses on the effect of dopants on magnetic and SC properties of La2-xSrxCuO4 (LSCO) cuprates. The main research question is: does the SC mechanism has its origin in the magnetic properties of the material? This will be tackled in three ways: 1) The applicant will determine if the new theoretical prediction of the SC transition temperature increase with very small impurity content is justified for LSCO. This whole new effect will strengthen the case for magnetism-induced SC. 2) The applicant will study the low-temperature magnetic phase of LSCO when SC is fully suppressed by doping and field to provide new insights into the nature of intrinsic magnetic tendencies of LSCO. 3) The applicant will synthesize single crystals of completely new cuprates by replacing Sr by Sn, Zr and Ga to study how the ionic radii affect the magnetism-SC interplay. The project involves crystal synthesis, XRD, VSM and transport measurements and has a strong focus on elastic and inelastic neutron scattering experiments and data analysis. The applicant’s physics background and PhD in materials chemistry provide a strong basis for the experiments. The interdisciplinary nature of UCPH creates the ideal environment: the main supervisor Prof. Lefmann is an expert in neutron scattering with decades of experience, has all necessary physical characterization equipment and is a well-appreciated academic teacher. All relevant chemistry infrastructure and knowledge can be found within UCPH and close collaborators. In return, the applicant’s expertise in materials and crystallography will be a great addition to the Lefmann group.

Projet STABRT (Horizon 2020, appel à projets 2019)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Mathematics
Statut du projet : SIGNED

The overall aim of this project is to establish a new connection between representation theory and algebraic geometry. In recent years, great progress has been done in the understanding of stability conditions over module categories, notably in the description of the wall and chamber structure of finite-dimensional algebras via tau-tilting theory. During this fellowship I will undertake research that will lead to a deeper understanding of these stability conditions and I will apply these tools to the Homological Mirror Symmetry Program and the study of toric varieties. It is known that most of the information of wall-crossing phenomena of cluster algebras is encoded in the so-called cluster scattering diagram, recently introduced by Gross-Hacking-Keel-Kontsevich. In a seminal paper, Bridgeland showed that these scattering diagrams are intimately related with the wall and chamber structure of certain jacobian algebras. The wall and chamber structure of an algebra has a rich combinatorial structure. In particular, it has the structure of what is known as a fan in toric geometry. Each fan determines uniquely a toric variety. In this project, I will study tau-tilting theory and stability conditions in four different ways. From the more representation theoretic to the more geometric, these are the following: I will attack problems on tau-tilting theory related with the finitistic dimension conjecture; I will show how the wall and chamber structure of two algebras encode the homological relation between them; I will use the knowledge about wall and chamber structures for finite-dimensional algebra to study wall-crossing phenomena beyond the realm of cluster algebras; I will establish the relation between certain homological properties of finite-dimensional algebras with the homological properties of their associated toric varieties.

Projet METAGE (Horizon 2020, appel à projets 2017)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Life Sciences
Statut du projet : CLOSED

The overall aim of this proposal is to understand how early-life stress can affect later ageing biomarkers (oxidative stress, telomere shortening, and telomerase activity) in species with complex life-cycles, and in particular to test the completely new hypothesis that amphibian metamorphosis may act to rejuvenate tissues previously exposed to stress. The research objectives are: 1) to determine whether levels of ageing biomarkers vary across larval and metamorphic stages, 2) to investigate whether damage accumulated by larvae due to early-stress is reduced by metamorphosis and whether this differ between remodelled and newly formed tissues/structures, and 3) to examine whether early-stress influences cellular responses stressors to ageing biomarkers later in life. I will be trained by the host to adopt an empirical approach to measuring early-life stress and ageing (e.g. oxidative stress, telomere length, and telomerase activity) in species with complex life-cycles (using as a model Xenopus laevis individuals), and will learn new skills in several areas of animal physiology and molecular biology, which are needed to successfully complete the research objectives. This training will increase my experience in different biological domains and will help me to develop my independent research group in the EU.

Projet TECNO (Horizon 2020, appel à projets 2019)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Physics
Statut du projet : CLOSED

The overall goal of TECNO is to become an enabling technology for InSb-based devices on Si, which has numerous and wide-ranging applications, such as IR sensing, Majorana zero mode devices, and high-performance cryogenic amplifiers. For this purpose, I propose an innovative approach to template-assisted selective deposition. In the currently implemented integration technology at IBM, I will replace the semiconductor deposition process (MOCVD) by electrochemical methods. This will enable entirely new possibilities of integrating III-V semiconductors on silicon for sensing and quantum computing. TECNO will result in an solution-based technology for the preparation of high-quality multicomponent semiconductor materials and validate the proposed path by demonstrating functional electronic devices on silicon. The aim of the project is also to significantly expand my knowledge base and therefore amplify the impact of my research as well as my career prospects. TECNO ideally demonstrates the mutual overlap of typically quite separate fields, i.e. chemistry with solid state physics and device engineering. My deep expertise in electrochemistry perfectly matches the requirements of IBMs semiconductor interests and their integration technology. It is truly beneficial for both parties involved. IBM will benefit from my electrochemical solution expertise, while I will learn how to push my work to another level of maturity and impact in an industrial environment.

Projet SOCIENTITY_PR (Horizon 2020, appel à projets 2019)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Economic Sciences
Statut du projet : SIGNED

The overall goal of the action is to understand and uncover the role of social identity on the formation of preferences for redistribution. The fellowship will be carried out at the University of California, Los Angeles for 24 months and at the University of Cyprus for 12 months. The research objectives of the proposed research are twofold: (1) Investigate the effect of social identity on preferences for redistribution and (2) Investigate the existence of multiple regimes and parameter heterogeneity on preferences for redistribution. To achieve Objective 1 the fellow will employ social interaction models using innovative parametric and nonparametric techniques allowing for endogeneity in order to capture the high-dimensionality of social identity, aiming to identify the social factors that determine preferences for redistribution and a broader range of socioeconomic attitudes and beliefs. To reach Objective 2 the fellow will use novel econometric methodologies such as threshold regression models that account for social factors and account for the endogeneity of the threshold variable, aiming to identify a set of threshold variables that classify preferences for redistribution into various regimes based on individual, belief, and social heterogeneity. The fellowship will result in high quality research as well as targeted policy papers aimed at eliminating several negative social phenomena, impacting the academic community, the Cypriot and European policy makers and the general public. The fellowship will have a multidimensional impact on the fellow’s current and future academic career. It will advance his research knowledge and skills, improve his teaching abilities, build a network for future collaborations, novel ideas and high quality research, become more independent in his work, and gain critical project management skills.

Projet DrugSearchTool (Horizon 2020, appel à projets 2016)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Chemistry
Statut du projet : CLOSED

The overall goal of this project is to develop a universal FRET-based toolkit for screening of drugs targeting microRNA (miRNA). Specific outcome will be a high-throughput assay for finding drugs targeting miRNA-96, a tumor-suppressing miRNA in pancreatic cancer cells. FRET is the technique of choice and recently, Prof. Marcus Wilhelmsson, Chalmers University of Technology (CHALMERS; project main supervisor) pioneered the development and photophysical characterization of fluorescent base analogues (FBAs) optimized for high-resolution FRET analysis of nucleic acid systems. There is an urgent need in pharmaceutical industry for an in vitro, cell-free, pre-miRNA-small molecule interaction high-throughput assay and also to increase the understanding of the nature of miRNAs. In this project, the unique FRET FBAs will be utilized to develop such assays and to provide new knowledge regarding miRNA structure, dynamics and interactions with other biological molecules or drugs. Apart from taking on the new research field stated above and developing my professional skills, I will bring in new competences to CHALMERS in RNA biochemistry (from the University of Warsaw and Max Planck Institute in Göttingen). Moreover, as part of my training, I will carry out research at AstraZeneca (AZ) and Gothenburg University (UGOT) through secondments. CHALMERS/AZ/UGOT have an established collaboration and I will take full advantage of their R&T capacities in order to gain interdisciplinary and intersectoral expertise as well as to master my skills in scientific communication, scientific writing, coordinating research projects, results exploitation, critical assessment, mentoring, supervision, presentation and networking with other researchers across the globe. This MSCA Postdoctoral Fellowship will help me reaching a position of professional maturity invaluable for starting up my own research group or taking leading roles in industrial R&D organizations.

Projet ACSol (Horizon 2020, appel à projets 2019)
Action : Postdoctoral Fellowships - European Fellowships
Panel : Social Sciences and Humanities
Statut du projet : SIGNED

The overall objective of my research programme is to develop an account of anti-colonial solidarity grounded in the global history of political thought, and to work out anti-colonial solidarity’s contribution to contemporary political theory. I take my cue from the recent emphasis on the practical dimensions of solidarity in analytic political theory. On this account, solidarity is best understood as a particular mode of action, through which agents attempt collectively to redress the effects of injustice or to contest the structures that produce and sustain it. But my project is motivated by the following hypothesis: that the history of anti-colonial solidarity is best able to clarify solidarity’s practical and global dimensions. The first theories of solidarity were primarily concerned with nation building in modern France. But against and alongside these classical accounts, the central figures of my research project developed alternative models of solidarity in anti-colonial movements explicitly oriented transnationally and globally. Cuban revolutionary José Martí, Haitian statesman Anténor Firmin, and American Pan-Africanist W.E.B. Du Bois used solidarity to link local struggles against colonial domination around the world. By investigating these anti-colonial writers, and their understanding of the relation between local, transnational, and global political struggles, my research: (i) contributes to and expands on recent developments in analytic political theory by identifying anti-colonial solidarity as a distinct type of solidarity. In doing so, I (ii) develop a new perspective on solidarity that exceeds the ‘top-down’ models of cosmopolitanism that have long dominated political theory. I also (iii) excavate a crucial but neglected chapter in the global history of this contested political value.

Projet Robust OTFT sensors (Horizon 2020, appel à projets 2016)
Action : Postdoctoral Fellowships - Global Fellowships
Panel : Physics
Statut du projet : CLOSED

The overall objective of “Robust OTFT sensors” is to apply Dr. Nikolka’s expertise in material science and organic electronics to the field of organic sensors. The aim of the specific project is to explore the use of state-of the art conjugated polymers as a platform for flexible, low-cost lactic acid sensors and biosensors. Dr. Nikolka will therefore spend time in Prof. Zhenan Bao’s group (Stanford University), which is world leading in the areas of electronic-human interfaces, e-skin and biological sensing technologies. In Prof. Bao’s group, he will learn the experimental techniques required for work on (bio-) sensors including microfluidics, flow-cell setups or the functionalization of surfaces. To ensure a successful project outcome, Dr. Nikolka will build on his previous work and achievements, such as the discovery of high performance, disorder free polymers (Venkateshvaran*, Nikolka* et al., Nature, 2014) or the demonstration of high operational and environmental stability of high-mobility conjugated polymer through the use of molecular additives (Nikolka et al., Nature Materials, in 2nd stage review). The project is aimed at providing Dr. Nikolka with the techniques and tools to grow as an independent researcher which he will be able to demonstrate during the return phase by combining novel sensors designs with printing techniques pioneered at Cambridge University. “Robust OTFT sensors” will furthermore enable Dr. Nikolka to profit from training and educational programs and allow him to gain essential skills in project management, leadership and financial independency. Finally, it is the goal of the project to create a strong international collaboration between the outgoing and return host laboratories and connect expertise in sensing (Stanford) with the expertise in printed organic semiconductors (Cambridge). This work could lead towards various low-cost sensors for biomedical or lab-on-a-chip applications having a direct and profound impact on society.
