Bulgarian Academy of Sciences appointed her in the Institute of Physics in 1968. She worked there until her death.

    She founded a new laboratory for biocompatible materials in 2006 and leaded it up to 2015.

Award

Institute of Solid State Physics honoured her with "G. Nadjakov" medal on a ribbon.
