Research Statement


Our research has focused on venomous marine snails, in particular, those that belong to the genus Conus ("cone snails"). Cone snails are highly specialized venomous predators. We estimate that there are over 100,000 pharmacologically-active peptides in the venoms of cone snails, and well over 2,000,000 natural products in the venoms of all venomous marine snails (in the superfamily Conoidea). The major research project in our laboratory is the discovery and characterization of these venom components, identification of their molecular targets, and an exploration of potential biomedical applications. The phylogeny of the genus Conus has been extensively analyzed, and the ~15-20 definable clades comprise species that specialize on either marine worms, other molluscs or fish as prey. The detailed molecular mechanisms that underlie the capture of fish by the fish-hunting cone snails has been elucidated in considerable detail by our laboratory; most (but not all) active components in these venoms are small peptides (12-30AA), and most of these are targeted to ion channels and receptors in the nervous system. One of the peptides that was isolated by a University of Utah undergraduate in our laboratory has become an approved drug for intractable pain. Recently, we have discovered a novel source of previously inaccessible venomous snails, providing access to a much greater chemical diversity.
