During his PhD at Institute Jozef Stefan, Možina developed new catalytic systems for aromatic nitration and oxidation of alcohols using fluorinated solvents. He has done two years as postdoc student at National Chemical Institute where he was reseraching formation of complex between DNA and small organic molecules. At the moment his point of interest lies in developing new bioactive molecules for gyrase with a goal to use them as a new drug aginst gram-negative bacteria.
