PhD student in Theoretical Physics at the Rudolf Peierls Centre, University of Oxford

Clarendon Scholar

I am supervised by Professor Michael Barnes and work on plasma turbulence in stellarators. The idea of my project is to understand how turbulence carries heat out of a magnetically confined plasma, and how this depends on the three-dimensional shape of the magnetic field.

Rome

2002 — 2021

I was born in Rome in 2002. My interest in mathematics and physics began in my final year of middle school. From then on, I enjoyed taking part in Olympiads—even when the results were mixed.

I attended Liceo Scientifico Augusto Righi, where I met my first community of future mathematicians and physicists. Many of them are still close friends.

Pisa

2021 — 2026

I moved to Pisa for university, studying physics at the University of Pisa and the Scuola Normale Superiore. There, I could finally devote myself full-time to the subjects I enjoyed most.

Oxford

2025 — today

I first moved to Oxford for six months in October 2025. I worked with Alex Schekochihin and Plamen Ivanov on my master’s thesis, studying coherent structures in plasma turbulence (the PDF is in the University of Pisa archive , under embargo until 2029).

Among the options available to me for the PhD, I chose to stay in Oxford. Since October 2026, I have been working with Michael Barnes, Daniel Kennedy and Richard Nies on plasma turbulence in stellarators. My PhD is supported by a Clarendon Scholarship and by the Max Planck Institute for Plasma Physics in Greifswald.

Magnetic confinement in stellarators

Magnetic surfaces

A plasma is a gas of electrons and ions. In a magnetic field, these particles gyrate around field lines and can move along them. In the core of a stellarator, the field lines wind around nested magnetic surfaces. This geometry forms the basis of magnetic confinement.

Coils and vacuum vessel

External coils produce this three-dimensional field. In Wendelstein 7-X, 50 non-planar and 20 planar coils allow its geometry to be controlled. The vacuum vessel encloses the plasma and separates it from the surrounding atmosphere; the cutaway shows how its shape follows that of the confined volume.

Plasma cross-section and transport

The cross-section shows the nested magnetic surfaces. The field restricts transport across these surfaces, but does not eliminate it. Collisions and turbulence can carry particles and energy outwards. Understanding these losses is essential to assessing how effectively the plasma retains heat.
