Roberto Purrello (b. April 12 1956) is Full Professor of Chemistry at the Department of Chemical Sciences of Catania University. He received his Laurea Degree in 1979 (summa cum laude) and in 1983 he started his academic career in Catania as Assistant Professor. In 1988 he received a travel grant from CNR and joined Tom Spiro’s group at the Department of Chemistry of Princeton University to work on UV-Resonance Raman of nucleic acids and proteins. From 1989 to 1990 he was appointed as Research Assistant in Princeton and in 1991 he was appointed as Associate Professor in Catania. From 1992 to 2000 he visited the Department of Chemistry of the Swarthmore College (PA, USA) for various short periods (one-two months) collaborating with Prof. R. F. Pasternack. In 1999 he was appointed as Visiting Fellow at the Department of Chemistry in Davis (CA, USA) in the laboratory of Prof. K. M. Smith. In 2000 he became Full Professor at the Department of Chemical Sciences in Catania. Since 2003 he has been collaborating with Prof. N. Berova and professor K. Nakanishi at the Department of Chemistry of Columbia University (NY, USA). He is member of the Editorial Board of “Chirality” from July 2010 and member of the International Scientific Committee of the “International Conference on Chiroptical Spectroscopy”.
