Curriculum Vitae (version of October 2020)


Przemysław Figura (Postdoc)

He joined our team in 2021. Przemysław Figura graduated from Astronomy Department of the Warsaw University, and completed PhD thesis in 2018, at the Center for Space Research of the PAS, in Warsaw. After that, he worked within the VIRGO collaboration, on position financed from the Foundation for Polish Science, TEAM project held at Astronomical Observatory, University of Warsaw. In the project he was responsible for developing the time series and spectral data analysis methods. In our team, Przemek specializes in modeling of stellar evolutionary models of massive stars, which will eventually collapse to black oles and become progenitors of long gamma ray bursts.

Fatemeh Hossein-Nouri (Postdoc)


Fatemeh Hossein-Nouri was a former postdoctoral researcher at Inter-University Centre for Astronomy and Astrophysics (IUCAA) in India, and a current member of the SXS collaboration in the US. She has received B.Sc. in physics from K.N.T. University of Technology in Iran, and M.Sc. and PhD degrees in physics and astronomy from Washington State University in the US. Her PhD thesis was focused on GRMHD code development in Spectral Einstein Code (SpEC), and numerical simulations of magnetized accretion disks around spinning black holes. In her recent research at IUCAA, she studied hydro instabilities in neutron star binary systems as a result of nonlinear coupling between star’s oscillation modes and tidal fields. Her research interests are numerical relativity, astrophysical hydrodynamics, physics of the compact objects and high energy astrophysics.
