Тема кандидатської дисертації: 

Hydrophobically modified reagent systems for fluorescence determination of organic compounds of ionic nature

Scientific interests: 

Investigation of factors influencing the analytical signal of ionic surfactants in organic reagent - surfactant systems in solutions, identification of supramolecular matching effects in the association of reagents with surfactants and development of practical recommendations for the rational creation of surfactant-modified reagent systems and methods for determining hydrophobic organic compounds of ionic nature by molecular spectroscopy.
