Main Research Fields

My main research interests lie in the study of active galactic nuclei (AGN) and the co-evolution of supermassive black holes and their host galaxies. I use multi-wavelength observations to investigate how black holes accrete matter from their surroundings and return energy to their host galaxies and larger-scale environments through winds, outflows, and relativistic jets.

Using large statistical samples of AGN, I study the physical mechanisms governing black-hole accretion and feedback, with a particular focus on questions such as:

• How does the accretion mode influence the power and properties of relativistic jets and outflows?

• How do accretion and jet-launching mechanisms scale with black-hole mass, and to what extent are these processes mass-invariant?

• What is the global impact of AGN feedback on galaxy evolution across cosmic time?

More recently, I have become interested in identifying and characterising AGN in low-mass and dwarf galaxies. Nearby dwarf galaxies may provide valuable analogues of some of the physical conditions present in the first galaxies, and therefore offer an important window onto black-hole growth in the early Universe. Follow-up studies, particularly, with ESA’s XMM-Newton, will provide crucial insight into the accretion and feedback properties of AGN in the largely uncharted regime of low-mass galaxies.
