Giorgio Molteni, born in 1963, received his MSc and PhD in Chemistry at the University of Milan. Since 2001 he was appointed Assistant Professor at the Chemistry department of the same University. He explored the synthetic, mechanistic and theoretical aspects of 1,3-dipolar cycloadditions. Recently, his research activity relies upon the catalysis of cycloadditions by metal-oxide nanoparticles and the behaviour of 1,3-dipolar species in aqueous medium. He is a member of the National Centre of Pericyclic Reactions.
