He completed his astronomical studies at Nicolaus Copernicus University in Toruń, and obtained a PhD in physics from the University of Warsaw. He was a scholar at the University of California, Berkeley, and Los Alamos National Laboratory. He conducted research as a visiting research fellow at Princeton University and the Institute for Advanced Study, and as a visiting scholar at the Department of Astronomy and Astrophysics at the University of Chicago. He also worked at the Centre National de la Recherche Scientifique (CNRS) in Paris, the Yukawa Institute for Theoretical Physics at Kyoto University, the Goddard Space Flight Center, the Center for Theoretical Astrophysics in Copenhagen, and the European Southern Observatory Headquarters in Garching bei München. From 1993 to 1996, he was a member of the COBE satellite team, which first measured the anisotropy of cosmic background radiation. Since October 1997, he has been involved in the Planck satellite mission, for which he and his team were awarded the prestigious Gruber Cosmology Prize in 2018. Currently, he works at the Astronomical Observatory of the University of Warsaw, as well as at NASA's Jet Propulsion Laboratory and the California Institute of Technology (since 2003). He is the recipient of numerous awards and honors, including the NASA Exceptional Achievement Medal (2011), NASA Exceptional Technology Achievement Medal (2019), the Foundation for Polish Science Prize (2020), and the NASA Exceptional Public Service Medal (2023).
