Our research primarily involves the study of symbioses of bacteria in marine invertebrates from deep-sea hydrothermal vents, methane seeps, and coastal reducing sediments. Specific emphasis is placed on the characterization of metabolic and genetic capabilities of symbionts, evolutionary relationships with free-living bacteria, and co-evolution of host and symbiont.
