'Death Stars' from Bacteria We discovered that bacteria produce tiny syringe-like structures that inject toxins into animal cells. These syringes could someday be harnessed for biotechnology purposes to deliver therapeutics to human cells.

Bacteria-Induced Metamorphosis Bacteria-induced metamorphosis is critical for coral reef formation and causes the costly accumulation of encrusting organisms on the hulls of ships (i.e., biofouling). However, the molecular interactions that mediate bacteria-stimulated development remain enigmatic.

Bacteria Wield Harpoon-Like Structures to Induce Animal Metamorphosis We identified a harpoon-like structure that induces metamorphosis. These structures are related to bacterial viruses (the tail of bacteriophage). We named these structures MACs (Metamorphosis Associated Contractile structures).

A MODEL FOR MICROBE-ANIMAL INTERACTIONS Studying a simple bacteria-animal interaction will expand our fundamental understanding of how bacteria benefit animals and potentially yield new methods to manipulate microbes for beneficial purposes.

We study the tubeworm, Hydroides elegans, which require interactions with bacteria to metamorphose and complete their lifecycle.​
