I finished my PhD in astrophysics at the University of Ljubljana under the supervision of prof. dr. Tomaž Zwitter. My current research interest is peculiar emission-type stars, classification of stellar spectra, and double lined spectroscopic binaries. I conduct my research as a member of one of the working groups in each Gaia-ESO and Galah spectroscopic surveys.

Other interests: binary and multiple systems, stellar evolution, stellar ages, stellar classification, peculiar stars, Galactic archaeology, stellar spectroscopy


2012: M.Sc. in physics, University of Ljubljana: Pregled kinematičnih in kemičnih lastnosti zvezd projekta RAVE z metodo LLE (Overview of kinematical and chemical properties of RAVE stars using LLE), supervisor Tomaž Zwitter
2013: PhD student of astrophysics at the University of Ljubljana, supervisor Tomaž Zwitter.
