I am an observational cosmologist. I study the large-scale structure of the Universe and its luminous tracers - galaxies. I am interested in how matter clusters on the largest cosmic scales and how this affects the propagation of light originating both from galaxies and from the earliest epochs of the Universe, visible today as the cosmic microwave background.
I work with many wide-angle galaxy catalogs, and use various computational methods, such as machine learning, both to find galaxies in large datasets and to estimate their distances via photometric redshifts. I use such data, among other things, to study the effects of gravitational lensing on the largest cosmic scales.
At the Center for Theoretical Physics PAS, I co-lead the Computational Cosmology Group. I am also the principal investigator of the project “PACIS: Precision and Accuracy for Cosmological Imaging Surveys” funded by the National Science Center (NCN) within the Sonata Bis scheme.
I participate in many observational projects:
