Basic studies of CRISPR-Cas and bacteriophages for controlling the bacterial-antibiotic resistance threat

Our lab studies the adaptive immune system of bacteria: the CRISPR-Cas. This fascinating system specifically adapts to defend prokaryotes against newly encountered phages by launching a specific RNA-guided attack against their nucleic acids. We also study novel phage interactions with their bacterial hosts, and particularly interactions with defense systems such as CRISPR-Cas. These basic studies are translated to projects aiming at reversing antibiotic resistance and consequently countering the threat from antibiotic-resistant pathogens.
