I started my research work in the Laboratory for spectroscopy at
of Physics in Belgrade. The problem of stark broadening of Zn II lines
in conditions of laboratory plasma was my first topic and I defined my
MSc in this field.
Since 1992 I have been working at the Astronomical Observatory
in Belgrade on atomic processes in stellar atmospheres. Especially, I
investigated the stark broadening effect in stellar atmospheres and
has been also the subject of my PhD thesis.
In 1994 I started to investigate spectral lines of Active
Nuclei (AGNs). I am interested in spectral line shape investigation of
AGNs and in modeling the central parts of AGNs by using emission
i.e. describing the kinematics and structure of their central parts by
using the shapes and variability of emission lines of AGNs. Also, I am interested in
gravitational lensing effect (see e.g.
here), super-massive binary systems
(super-massive binary black holes, see here ) and violent processes in the Universe as
Gamma Ray Bursts - GBRs (see e.g.here and here ) .
Recently I started to work in spectro-polarimetry, especially in the determination
of the physical properties of the broad line region in AGNs. Additionally, we
give a new method for AGN black hole measurements (see e.g.
