Research focuses on oxidation effects in media, with particular emphasis on the identities and molecular structure of short-lived transients and reaction mechanisms. Subject involves application of radiation methods for the study of OH-induced oxidation of sulfur-containing alcohols, carboxylic acids, amino acids and their derivatives, and peptides.

It is concerned with the characterization and quantification of reactive intermediates, such as hydroxysulfuranyl radicals, radicals and radical cations with various 2-center/3-electron bonds, reaction kinetics and the measurement of absolute rate constants for elementary processes involving these reactive intermediates, such as intramolecular proton and electron transfer, beta-fragmentation, decarboxylation, and reaction with molecular oxygen. The sulfur intermediates can undergo a variety of subsequent reactions depending on conformational flexibility of molecules and functional neighboring groups present in molecules.
