The Gran Sasso Science Institute (GSSI) is a public international doctoral school in L'Aquila, Abruzzo, created by national law in 2012 after the 2009 earthquake to help relaunch the area. It began teaching in 2013/14 as a centre of INFN, Italy's national institute for nuclear physics, close to its Gran Sasso National Laboratories, and became an autonomous special-statute university school in 2016. It offers PhD programmes only, not bachelor's or master's degrees.
Yes, the Gran Sasso Science Institute is an international PhD school, and its doctoral programmes are run in English. It works in four areas: physics, with a focus on astroparticle physics; mathematics for natural, life and social sciences; computer science; and social sciences, with a focus on regional science and economic geography. There are no bachelor's or master's degrees, so if you are still at that stage, GSSI is a future goal rather than your next application.
The Gran Sasso Science Institute admits PhD students through an open, competitive international call, so you apply with a master's-level degree, or one you will complete in time, as the call specifies. Selection weighs your academic record, research potential and fit with the programme, and each call sets out its own selection stages. Competition is strong: in 2017 GSSI received more than 1,400 applications, the highest number of international applications of any Italian institute.
Applying to the Gran Sasso Science Institute starts with its yearly PhD call, published on gssi.it with the positions, requirements and deadline for each programme. Read it closely, because each programme sets its own documents and selection stages. Non-EU applicants who win a position still need a type D study visa, so leave time between the result and the start date. GSSI alone decides admission, and no adviser can influence the outcome.
A PhD at the Gran Sasso Science Institute is designed to be funded: selected doctoral candidates receive fellowships, and GSSI has also offered free accommodation at its facilities and use of a canteen. That model is very different from a standard Italian degree, where tuition follows family income (ISEE). Fellowship amounts, the number of funded positions and any fees are set in each year's call, so rely on the current call rather than older figures quoted online.
Gran Sasso Science Institute PhD students live in L'Aquila, where GSSI has provided housing for its doctoral students: a residence in the former Grand Hotel e del Parco from 2017 and, since 2020, the Collegio Ferrante d'Aragona, a college spread across buildings in the historic centre. Housing arrangements can change between cohorts, so confirm what your call offers. Living in the centre puts you close to GSSI's buildings and to the city's rebuilt old town.
The Gran Sasso Science Institute does not appear in the THE World University Rankings 2026 or ShanghaiRanking's ARWU 2026, which mostly assess large universities that teach at every level. That says little about a small PhD school. For a doctorate, the research group, your supervisor, recent publications and the international network behind your programme matter far more than any overall table. Look at recent GSSI papers and at where its PhD graduates went next.
Life at the Gran Sasso Science Institute means living in L'Aquila, the capital of Abruzzo, a mountain city that has been rebuilding its historic centre since the 2009 earthquake. GSSI was founded partly to support that recovery, and its offices and classrooms are in the city. The Gran Sasso massif and INFN's Gran Sasso National Laboratories are nearby, which matters for physics students. Expect a quieter pace than Rome or Naples and a close-knit international research community.
The Gran Sasso Science Institute is a PhD-only school, while the University of L'Aquila, in the same city, is a full public university with bachelor's, master's and PhD programmes. L'Aquila is 13th among Italy's medium-sized public universities in Censis 2026/27 and in the 601 to 800 band of THE 2026. GSSI belongs to Italy's small group of special-statute schools, alongside SISSA in Trieste and the Scuola Normale Superiore in Pisa, which focus on advanced study and research.
The Gran Sasso Science Institute suits you if you hold, or will soon hold, a strong master's in physics, mathematics, computer science or regional science and economics, and want a funded, research-intensive PhD in an international group. It suits you less if you want a taught bachelor's or master's, a big-city lifestyle or a subject outside its four areas. If you are at master's level now, an English-taught master's at an Italian public university can be the stepping stone.
ApplyAZ builds shortlists of 20 to 30 English-taught degree programmes at Italian public universities, and a PhD at the Gran Sasso Science Institute is a different route: strong researchers usually apply directly through its call. If you are still at bachelor's or master's level, we can plan the degree that prepares you for a PhD, write your CV and SOPs, and handle applications, DSU and visa, with a named person owning each stage and no university commissions.
