Scientific interest

1. Active Galactic Nuclei (investigation of physical and kinematical properties of AGN center- see e.g.Fe II in AGNs )
2. Gravitational lenses (Influence of lensing to the QSO spectra) MLE
3. Stark Broadening (Calculation the collisional parameters in stellar atmospheres, see e.g. Nd II in stellar atmospheres)
4. Gamma Ray Burst (Modeling the mechanism for creation of gamma ray bursts)

I started my research work in the Laboratory for spectroscopy at the Faculty 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 have investigated the stark broadening effect in stellar atmospheres and this has been also the subject of my PhD thesis.
In 1994 I started to investigate spectral lines of Active Galactic Nuclei (AGNs). I am interested in spectral line shape investigation of AGNs and in modeling the central parts of AGNs by using emission lines, 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 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. here )
