Applications range from mathematics to physics, from engineering to life sciences, from chemistry to climate science, and even to health and medicine.
Educational Objectives
The central aim of the HPSC PhD programme is to provide highly specialised theoretical and practical training in high-performance computing technologies. The programme supports doctoral candidates on a comprehensive learning journey that includes:
- The design and optimisation of scalable algorithms;
- The development of advanced software for supercomputers and parallel architectures;
- The application of Machine Learning and Artificial Intelligence techniques to the analysis of large-scale data;
- The integration of computational tools in strategic scientific and technological contexts, such as climate modelling, biomedical research, computational engineering, and materials science.
Through personalised teaching and a modular training structure, the programme enables PhD candidates to address any disciplinary gaps and to build a strong, forward-thinking professional profile.
Interdisciplinary Research and Industrial Collaboration
A defining feature of the HPSC Ph.D. programme is its strong integration between academic research and the industrial sector. Each doctoral project is designed to foster collaboration across multiple departments and to directly involve industrial partners and research centres, thereby promoting technology transfer and the adoption of HPC solutions in real-world applications.
PhD candidates will have the opportunity to undertake research placements at the premises of the participating companies and research centres, engaging in real projects and contributing to the development of new technologies. For projects in collaboration with S.I.T., in particular, candidates will have access to radiofrequency, vacuum, and ionising radiation dosimetry laboratories, as well as participate in experimental activities related to Flash radiotherapy, one of the company’s key areas of focus.
These experiences will allow Ph.D. students not only to deepen their understanding of cutting-edge scientific and technological challenges, but also to gain insight into industrial processes and the requirements for translating research into practical solutions.
