The HINA consortium will also address the key doctoral training elements of academic and transferrable skills provision by establishing exciting and attractive academic and transferrable skills modules. In the different Area of Knowledge of the HINA programme, a specific programme of specialisation, tailored on the needs of the chosen research field available at the different partner places, will be proposed to the PhD students and specified in their Personal Career Development Plan. We will ensure co-ordinated provision of these key doctoral training elements that can best leverage on the international capabilities of the consortium, on its unique and complementary skills base reflecting both national and regional strengths and, on the on-going developments of new curriculum in the fields of materials, modelling, devices and systems for new telecommunication, computing, sensing (IoT & IoH) technologies. The academic skill provision will build from the assumption that all the centre skills education programmes will be modular, with specific credit modules and available across the partner centre sites using both traditional (lecture, seminar, summer school, workshop) and now widely developed web-based delivery by most of HINA academic partners and world leading universities. A key topic for 21st century engineers will be technology management including topics such as technology innovation and intellectual asset management. The opportunity for the DCs to explore and acquire these multidisciplinary skills within the international context of HINA will uniquely position them for the future. The rapid race of engineering research and the steady integration of engineered technology in our infrastructure and life, calls for more involvement from engineers, scientists, and technologists in the setting of public policy and in participation in the civic arena. **DC16 (Starting date October 2025): Study of photoelastic and acousto-optic effects in KNTN based devices** At PIEMACS (doctoral school UBFC) Supervisors: P. Muralt (PieMACS), S. Margueron (UMLP) Objectives: (i) To study the acousto-optic coupling efficiency and photo-elastic effects in the embedded waveguides and the impact of piezoelectrically excited deformations on the “transport” conditions, (ii) to demonstrate acoustic wave strong interaction with photons in KNTN materials (acousto-optic performance increased at least by a factor of two with respect to the-state-of-the-art of acousto-optic performance in LNOI). **Prise de fonction**: - 31/10/2025 **Nature du financement**: - Financement de l'Union européenne **Précisions sur le financement**: - MSCA Doctoral Network HINA **Présentation établissement et labo d'accueil**: - MSCA Doctoral Network HINA - Hybrid INtegration of Alkaline niobate - tantalate films for advanced photonic and piezoelectric devices - advanced material - designed device - smart system". The HINA project also seeks to intensify the relationship between academic and private sectors, and to train highly skilled young researchers for new materials and device technologies. Both are essential to provide a strong European lead over the rest of the world in this highly competitive technologies. The HINA consortium partners recognise that engineering graduates face a rapidly changing work environment, with short product development times and life cycles, rapid evolution of knowledge, new methods of working, and, of course, new career paths and opportunities outside those of traditional PhD academia and research. It is therefore essential to prepare them to address both these challenges along with the complex technical, social, commercial and ethical questions raised by emerging engineering technologies (e.g. nanotechnologies, energy, healthcare, environment, raising living standards, new communication & information technologies, data era, etc.) and practices.
