Stefania joined the Russell group as a postdoctoral scholar in July 2005. Her work focused on the analysis of organic functional group composition by Infrared Spectroscopy to study aerosol climate relevant properties. She also investigated aerosol mixing state using Near Edge X-Ray Absorption Fine Structure Spectroscopy. She participated to the MILAGRO and INTEX-B field campaigns. She is now a senior researcher at the Institute of Polar Sciences of the Italian National Research Council.
