AstroCeNT — the ultra-modern Particle Astrophysics Science and Technology Centre of the Polish Academy of Sciences — was established in Warsaw in 2018. Currently, under the leadership of Prof. Leszek Roszkowski the Centre implements its research program, attracting scientists from all over the world. Dr. Marcin Kuźniak joined the team in 2019 as the leader of the group that is working on the improvement of silicon photomultipliers — technology extremely important for both science and industry. Marcin told us about his path to astrophysics, 10-years’ experience in Canada and return to Poland, as well as about the projects developed by AstroCeNT.
