I am currently a post-doctoral STRUCTURES fellow in Heidelberg, working jointly at the Max-Planck-Institut für Astronomie (MPIA) with Annalisa Pillepich and at the Zentrum für Astronomie (ZAH/ITA) with Ralf Klessen and Simon Glover. Before this, I defended my PhD in 2016 at the Observatoire de Lyon under the supervision of Jérémy Blaizot, and then moved to the Institut d’Astrophysique de Paris, where I worked with Marta Volonteri.

My research interests embrace various aspects of the formation of galaxies at high redshift. I spend most of my time thinking about the Epoch of Reionization: this correspond to the first billion years of the Universe, during which massive stars and active galactic nuclei (AGN) shine and ionize the surrounding Intergalactic Medium (IGM). I focus on the following broad questions:

  • How do early galaxies form their stars, and how are they affected by the subsequent feedback?
  • How do massive black holes at the centre of galaxies grow and power AGN, and how does this impact their host?
  • How much ionizing radiation is produced by these galaxies, and how much of it escapes to reionize the Universe?

I address these questions using cosmological simulations, mostly with the AMR code RAMSES, and its radiation-hydrodynamics RAMSES-RT.

Together with a group of collaborators between the IAP, Lyon, Oxford and Yonsei University, I recently started a large simulation project called Obelisk to model the formation of a protocluster until the peak of cosmic star formation (around z ~ 2). There will be more details soon on a dedicated page…
