I am currently working on the synthesis and the test of new hydrogen sulfide (H2S)  donor organic molecules mitochondria-targeted (and others)  and on the study of  the H2S release mechanism. Hydrogen sulfide has been shown to have a potential protective role in a number of disease states including diabetes and various kidney disorders and to have a major role in the regulation of a number of vital biological functions in mammals.

I graduated in Chemistry and I have always had a particular interest in Organic Chemistry and organic synthesis. I worked for 6 months at the KU-Leuven University (Belgium).  My project at KU-Leuven involved: reactions under homogeneous and under heterogeneous phase catalyzed by silver salts and silver nanoparticles; reaction assisted by microwave. In my experimental  thesis, that I carried out at  the University of Torino (Italy), I  synthesized and tested a new organic Brønsted acid chiral catalysts.
