Laurea in Chemistry, Universita' di Bologna (Italy), 2006
Ph.D. in Chemistry, University of Miami, FL (USA), 2012

Stefania was born in Mantova, Italy. In 2006 she received a Laurea in Chemistry, cum laude, from the University of Bologna, with a thesis on the photophysical and electrochemical properties of molecular machines based on modular rotaxanes, under the supervision of Alberto Credi and Vincenzo Balzani, and in collaboration with 2016 Nobel Prize in Chemistry, Fraser Stoddart.

After spending one year as researcher at the Department of Chemistry "Ciamician", University of Bologna (Ciba-Geigy Additives Division Fellowship), she entered the graduate program in chemistry of the University of Miami, FL, in 2007, in the group of Françisco M. Raymo. Her research focused on the design and the development of supramolecular strategies to circumvent diffraction and permit the visualization and the intracellular optical control of biological samples with resolution at the nanometer level, particularly photoswitchable fluorescent assemblies based on semiconductor nanoparticles and photochromic components. Stefania obtained her Ph.D. in Chemistry in January 2012 (with Award of Academic Merit) with a dissertation titled “Engineering of Nanoparticles for Luminescence Switching”, and joined Tito Scaiano’s group in March 2012.

Within the Scaiano group, Stefania's research is focused on the synthesis of gold, silver, ruthenium, niobium, and other metal-based nanomaterials for applications in catalysis, as well as in the custom design of supramolecular systems or single-molecule switchable probes for the investigation of catalysis with fluorescence microscopy. In 2013, she was awarded the prestigious Banting Postdoctoral Fellowship for two years with the project "Plasmonic Nanoswitches: Light-Driven Molecular Devices for Rewritable Materials - Green Nanotechnology for Rapid and Secure Communications".
