We are a chemical biology group that focuses on the study of natural products. Natural products are highly evolved and functionally privileged compounds that often display complex chemical structures. These molecules have inspired generations of synthetic organic chemists, unveiled numerous fundamental biological processes as chemical probes, and served as the most significant source of chemical matter for drug discovery.

As the field of genomics has expanded, it has revealed a vast untapped wealth of natural products encoded in the DNA of sequenced organisms, particularly bacteria. Our lab has developed new tools to expedite the discovery of natural products from genomic data, including molecules from bacteria that cannot be cultivated in a lab. In particular, our lab focuses on Ribosomally synthesized and Post-translationally modified Peptides (RiPPs) which have genetically encoded substrates and an incredible diversity of post-translational modifications. Using a genes-to-molecule approach, we have uncovered numerous structurally unique RiPP molecules and revealed the unprecedented mechanistic enzymology through which they form. We then leverage the new biosynthetic knowledge to produce new-to-nature compounds with improved or novel activities with the long-term goal of unleashing the full biosynthetic potential of Nature to reshape the diagnosis and treatment of human disease.
