Tanja obtained her PhD in Physics at the University of Stockholm. Her research interests lie in the field of observational astrophysics and cosmology, in particular astrophysical transients such as supernovae and luminous flares from centres of galaxies. She is part of the LensWatch collaboration that aims to study strongly lensed supernovae and the ePESSTO+ collaboration, a Public ESO Spectroscopic Survey for Transient Objects, where she is active in the Tidal Disruption Events group. She is also a member of the Vera. C. Rubin Dark Energy Science Collaboration and the Strong Lensing Collaboration. Her scientific achievements were recognized with a Slovenian Presidential award in 2019. She led a National postdoc grant from 2019 to 2022.
