Who?
I am an astroparticle physicist with a background in theoretical computer science. My research focuses on very-high-energy gamma-ray astronomy, with a particular emphasis on gamma-ray cosmology, which uses distant gamma-ray sources as probes to study the electromagnetic content and structure of the Universe. I am an active member of the Cherenkov Telescope Array Observatory (CTAO) Consortium and the Large-Sized Telescope (LST) Collaboration.
You can find my CV here. My Ph.D thesis, titled Gamma-ray cosmology – Conclusions from three decades of extragalactic gamma-ray astronomy and perspectives for CTAO, can be found here. My pronouns are he/him.
