Curriculum vitae

Studied in Kyiv National Taras Shevchenko University at physics department (1994-99) and as PhD student at experimental physics division (1999-2002).
From 2002 till 2003 worked as leading engineer at Institute of Molecular Biology and Genetics of NAS of Ukraine; from 2003- as engineer in Kyiv National Taras Shevchenko University.
In 2005 has defended PhD theses “Spectral manifestation of interaction of cyanine dyes in water solutions and at the DNA surface". 
From 2006 – junior researcher, from 2007 – researcher of experimental physics division at physics department of Kyiv National Taras Shevchenko University. Works also as assistant lecturer at the division of experimental physics and scientific collaboration in Institute of Molecular Biology and genetics of NASU.
Main directions of scientific investigations: investigation of fluorescent properties of dye molecules, photo-physical processes in this molecules, interaction of dyes with biological molecules (nuclear acids, proteins), electron excitation energy transfer in system DNA-dye, and the processes of dye molecules aggregation in solution and at the surface of biological molecules. 
Main achieved results: determination of H-aggregation nature of long-wave fluorescence of some cyanine dyes in water solutions and in the presence of DNA; determination of the structure of electron energy levels and electron transitions of J-aggregate with Davydov splitting of absorption, selectively formed at AT-sequences of DNA; determination of the mechanism of linkage of the series of dye molecules with DNA.
Has 43 papers (total number of publications – over 100).
