Coral Symbiosis and Spawning

Introduction Video:  The power of symbiosis

Symbiosis Biology

The beautiful and biodiverse coral reef ecosystem is built upon the back of a symbiotic interaction between corals and photosynthetic algal symbionts.  The symbionts produce food and stimulate growth of the coral skeleton, resulting in growth rates  to support the hundreds of species that comprise coral reef ecosystems.  My lab works on several aspects of coral biology and symbiosis, primarily using genomic, cellular, and bioinformatic approaches.

Host-microbe interactions

Aiptasia pallida

Under the growing stress to coral reefs from coral bleaching and disease, there is a critical need for systematic understanding of how cnidarians respond to the myriad of microbes they encounter in the marine environment, including pathogens and their own symbionts.  

Reproductive genomics of cnidarians

Acropora digitifera spawning

We are examining the genetic underpinnings of reproductive cycles in cnidarians using a comparative genomic approach to identify cnidarian genes that exhibit cyclical patterns of expression correlated with the reproductive cycle.
