I am mostly interested in Magnetohydrodynamics and Plasma Physics, as frameworks for describing the behaviour of ionized matter under the influence of magnetic fields.
Astrophysical conditions can hardly be experimentally obtained on Earth. Thus, applying these frameworks to such situations allows not only the understanding of the relevant dynamical mechanisms but also the refinement of our own knowledge on those theories. As such, astrophysics can be seen as an ideal field for testing our representations of reality.

My research activity concerns the physics of magnetized Keplerian accretion discs driving jets and their connexion with their local environment. This includes:

• Jet formation:
• What are the various mechanisms for self-confined steady-state jet formation?
• What are the physical conditions required to steadily launch jets from accretion discs?
• What type of jets (terminal velocity, degree of collimation) can be produced?
• Asymptotic behaviour of jets
• Jet structure and stability
• Jet propagation and interaction with the interstellar medium
• Magnetic star-disc interaction
• Dynamics of 2D and 3D accretion funnel flows
• Rotational evolution of a protostar
• Time-dependent ejection events
• Magnetic instabilities and the source of anomalous transport coefficients in discs;
• Modelisation of observational signatures of magnetized jets from discs;
• Environment of black holes
• Advection/diffusion of magnetic flux
• General relativistic effects on MHD
• Long term evolution of accretion-ejection systems

Most of these themes find their applications in Active Galactic Nuclei or Galactic Radio Sources (where the central object is supposed to be a black hole) and Young Stellar Objects (where the central object is a protostar).
