In recent years, following the first detection of Gravitational Waves (GWs), we have witnessed the birth of GW Astronomy. So far, there have been more than 50 events recorded, providing us with invaluable information about the nature of the merging binaries. An exceptional case is the event GW170817, a Neutron Star merger, which was observed with both gravitational and electromagnetic (EM) waves. From a single event alone, by combining both ways of observation, we were able to vastly improve our understanding of such cataclysmic events. In the near future, in particular, in the early 2030s, the ESA Laser Interferometer Space Antenna (LISA) is going to be launched. LISA is a space-borne Gravitational-Wave observatory that, in contrast to the present ground-based detectors, is going to be signal-dominated. The LISA data will give us the unique opportunity to observe the merger of supermassive black hole binary systems, which in combination with the EM observations will enable us to push our knowledge boundaries in astronomy, astrophysics, and cosmology. With EMILIA, we aspire to enable multi-messenger astronomy with LISA, by developing a low-latency data analysis pipeline based on Machine Learning techniques. Our proposed methodology will take into account the source confusion problem of LISA, where monochromatic signals and noise artefacts are going to be classified as such and subtracted from the data. We will then apply a fast semi-analytical algorithm on the residual data, in order to swiftly estimate the sky position and time of coalescence of chirping signals. Such a scheme will enable the synergy of LISA and optical observatories on Earth and in space. A prime example is that of the LISA-Athena missions synergy, which would probe the existence of electromagnetic counterpart of massive black hole mergers and extreme mass ratio inspirals, or phenomena like X-ray flares, disk re-brightening, and relativistic jet formations.

Despite the development of novel technologies such as millimeter-wave (mmWave) communications and 5G New Radio, current cellular networks will face difficulties to serve their users in ultra-dense scenarios due to the unprecedented growth of the mobile data traffic from various emerging data services. Unmanned Aerial Vehicles (UAVs) that carry telecommunication equipment are able to enhance the wireless connectivity in such scenarios through an on-demand redistribution of the network resources. However, their progress is still hindered by three significant issues, i.e., the lack of a consistent UAV communication framework, the energy supply, and the efficient orchestration. To that end, the HERMES project proposes a holistic approach to tackle the limitations of aerial networks by employing state-of-the-art tools and a coherent research methodology. More specifically, mmWave, optical wireless, and sub-6 GHz communication technologies along with novel multiple access techniques will be investigated to define a comprehensive communication architecture. Solar-powered charging posts with wireless power transfer capabilities deployed around the serving area will be proposed and studied to encounter the energy supply issue. Also, artificial intelligence-based tools will be leveraged to provide an efficient and profitable orchestration of the UAVs by taking into account weather and user mobility patterns. In the end of the project, a proof-of-concept demonstration and a techno-economic analysis will unravel the intrinsic characteristics of aerial networks to showcase the significant advantages of the HERMES vision that will aid the fellow to network with industry and academia, and to empower him to become a research and development innovator.

This project will develop a new interpretive model to reveal the extent to which multiple socio-political transitions, representing different forms of urbanism, affect human lifeways and deathways, in a diachronic perspective. This is achieved by implementing an interdisciplinary methodology combining archaeological and historical theory, macroscopic bioarchaeological approaches and stable isotopes. The diachronic case of Amphipolis in Northern Greece experiencing many different political models between the Late Archaic/Classical and Roman periods is an ideal case study. Human skeletal remains from 300 inhumation and 100 cremation burials, spanning between the 5th c. B.C. to 1st c. A.D. will be analyzed. Methods will include: 1) studying funerary practices and deathways, 2) investigating health and lifestyle and 3) exploring biodistance and human mobility. I will also initiate an open access collaborative morphological biodistance database to create long term impacts on human mobility studies. By moving to AUTh, I will work closely with Sevi Triantaphyllou, a top-leader in funerary practices and osteoarchaeology. Her expertise, along with resources and specialties of other distinguished staff members of School of History and Archeology provide the perfect environment for the multi-dimensional contextual training, necessary for the project and for my career metamorphosis. A period of secondment is included at BB-LAB (VUB), with Christophe Snoeck, an expert on isotopic geochemistry and a global pioneer on the topic of isotopic study of cremated human remains. My career goal is to be a research leader in Social Bioarchaeology, which this project will enable by developing an integrated method for the combined analysis of mortuary environment with lived experience. Through a multi-faceted training in core skills, along with supervision, teaching and public outreach, I will develop key resources to maximize the impact of my career advancement.
