The Copernican Revolution — the heliocentric model of the Universe introduced by Nicolaus Copernicus — is considered as one of the most significant achievements in the history of science. And yet, it luckily happened despite many obstacles and even then it could have become unnoticed and forgotten. The year 2023 marked the 550th anniversary of the birth of Nicolaus Copernicus which gave us additional motivation to have a closer look at his highly extraordinary life and achievement.

Professor Roszkowski works in the fields of elementary particle physics, particle astrophysics and particle cosmology. In particle physics he is mainly interested in models of "new physics" beyond the Standard Model, like supersymmetry, especially the recently discovered Higgs boson and new yet unseen particles whose traces are searched for at the LHC and in other collider experiments. In particle astrophysics he is mainly interested in the puzzle of the identity of dark matter and in elementary particle models of new physics providing its solution. In particle cosmology he works on implications of new physics for the properties and evolution of the early Universe.
