Marraffini Luciano 250

Dr. Marraffini received his undergraduate degree from the University of Rosario in Argentina in 1998 and his Ph.D. from the University of Chicago in 2007, studying bacterial pathogenesis in the laboratory of Dr. Olaf Schneewind. He was a postdoc at Northwestern University from 2008 to 2010 with Dr. Erik Sontheimer, where he pioneered studies on CRISPR-Cas immunity. Dr. Marraffini determined that that CRISPR-Cas systems target DNA molecules in a sequence-specific manner, a study that was key to understand the mechanisms of CRISPR immunity at the molecular level. In 2010 he joined Rockefeller University as assistant professor, where he continued uncovering fundamental aspects of the molecular mechanisms underlying CRISPR-Cas immunity, as well as its applications for genetic engineering of eukaryotic cells.
