I am a PostDoctoral researcher at Brera Astronomical Observatory, INAF, Merate, Italy. Currently, I am working on the Galactic Center with Gabriele Ponti. I did my Ph.D. at Nicolaus Copernicus Astronomical Center, Warsaw, Poland. During my Ph.D., I worked on ultraluminous X-ray sources, a particular class of accreting compact objects that defies the Eddington limit for accretion. More or less, my research is focused on accreting close objects visible in X-rays. I use data from NASA and ESA space satellites for my research like Chandra, XMM-Newton, NuSTAR, etc.
