Main Research Topics:

Gas-phase ion and neutral chemistry: ion-molecule reactions as simple models for bond activation reactions relevant to catalytic processes occurring at the active sites, such as single-atom catalysis; detection and characterization of new radical and neutral species relevant to inorganic chemistry and atmospheric chemistry; measurement of thermochemical data and kinetic rate constants; studies of multiply charged ions undergoing bond-forming chemical reactions; analysis of pollutants in air and water samples; studies of the decomposition routes of biomasses relevant to the formation of platform molecules.
