I am fascinated by the extremes. In astrophysics, this means the neutron stars, objects weighing more than the Sun but of the size of a city, composed of the densest matter currently existing in the Universe, and the black holes - manifestations of pure geometry of curved spacetime.

To learn more about these unusual objects, my research interests revolve around the gravitational-wave data analysis methods (and, in general, methods of analysing the difficult, noisy data) and modeling of various astrophysical compact objects using numerical general relativity and dense matter physics. This often requires a lot of coding, the use of high-performance computing (with hardware accelerators like the Graphical Processing Units) and the usage of novel types of machine learning algorithms, like the deep neural networks.

I work at the Nicolaus Copernicus Astronomical Center (CAMK) in Warsaw, Poland as an associate professor. In 2018 I’ve spent a year at the APC in Paris working in the gravitation group on problems related to astrophysics and machine learning.

My published works are accesible online thanks to the arXiv and NASA ADS databases.

Here is my scientific CV.

My group in Warsaw:

  • Magdalena Sieniawska (PhD student),
  • Filip Morawski (PhD student),
  • dr Marek Cieślar (post-doc),
  • dr Jonas P. Pereira (post-doc),
  • dr Paweł Ciecieląg (CAMK staff).
