Sandra Pizzarello is an Emeritus Professor and research professor in the School of Molecular Sciences at Arizona State University. She received her doctorate in biological sciences in 1955, from the Universitá degli Studi di Padova, Padova, Italy. She was a research associate with Farmitalia Research Laboratories Neuropharmacology Dpt. Milan, Italy from 1957-1960.
Her research for the last 30 years has been devoted to the study of the organic material in carbonaceous chondrite meteorites, with emphasis on the molecular, isotopic, and chiral characterization of their soluble compounds. More recently, it has focused on the study of the non-racemic amino acids of meteorites, with compound specific isotopic analyses as well as model syntheses that would mimic their prebiotic catalytic activity and reactions.

My research of over thirty years has been devoted to the study of the organic material in carbonaceous chondrite meteorites, with emphasis on the molecular, isotopic, and chiral characterization of their soluble compounds. More recently, it has focused on the study of the non-racemic amino acids of meteorites, with compound specific isotopic analyses as well as model syntheses that would mimic their prebiotic catalytic activity and reactions.
