My research is focused on phages, the viruses that infect bacteria. We study how phages work, and how we can exploit phage-derived entities for applications in human health. We also study anti-CRISPRs, which are phage-encoded inhibitors of CRISPR-Cas systems. We were the first to discover these fascinating and technologically useful proteins. My group combines expertise in phage biology, structural biology, in vitro biochemistry, and bioinformatics, allowing us to address questions through a multi-disciplinary approach.
