Scientific interest

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 defened 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 modelling 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. The basis of such investigations is the knowledge of different processes which are able to change the spectral line shapes of AGNs. My special interest is to learn more about the gravitational effect that influence spectral line shapes of AGNs . This effect should be strongly visible in X-ray lines (eg. Fe  K line). Since 1999 I have been involved in a project of the Institute for Astrophysics of the Canary Islands (P6/88): 'Relativistic and Theoretical Astrophysics' and I have started to work on the problem of gravitational microlensing influence on spectral line shapes.

Now I am interested in next subjects:

1. Gravitational lensis (Influence of lensing to the QSO spectra)
2. Active Galactic Nuclei (investigation of physical and kinematical properties of AGN center)
3. Stark Broadening (Calculation the collisional parameters in stellar atmospheres)
4. Gamma Ray Burst (Modeling the mechanism for creation of gamma ray bursts)
