About Me

I am a docent at Faculty of mathematics and physics, University of Ljubljana. My research interests are observational astrophysics, stellar spectroscopy, spectroscopyc surveys, interstellar medium, diffuse interstellar bands, galactic archeaology, open clusters, chemical tagging, computational methods, data reduction, and data mining.
