Personal Statement

My research interests are focused on the synthesis of radiation mitigators that selectively
compartmentalize in the mitochondria of non-malignant cells and the mechanisms of S-(de)nitrosation of proteins. 


1986    Faculty of Chemistry, Sofia University, Sofia, Bulgaria, EU-   M.S. degree in organic and in analytical chemistry.

1991    Bulgarian Academy of Sciences, Sofia, Bulgaria, EU- Ph.D. in biochemistry.
