Research interests

I am focusing on octocoral biodiversity, conservation and phylogenetics for my DPhil. Octocorals (a.k.a soft corals or gorgonians) are an understudied group of organisms found all over the world from deep to shallow waters in both polar and tropical seas. They are the dominant corals of the Caribbean, providing habitat for many reef creatures, and yet many aspects of their basic biology as well as species’ status remain mysterious. I am interested in the role these organisms play in island reef ecosystems and how their species richness and abundance affects their health in a context of human impact.

My DPhil is based on Utila, one of the Bay Islands of Honduras, which demark the eastern-most extent of the Mesoamerican Barrier Reef Complex. This is the first species-level study of octocorals around the island. I have uncovered more diversity than was expected which is either incredibly exciting or just an artifact of an obsessive taxonomist (I challenge you to find me a casual taxonomist). Octocorals are an interesting group of study organisms for many reasons but the following are what I have structured my research on:

  • Octocoral diversity on island ecosystems in relation to anthropogenic pressure.
  • The ever perpetual hunt for a perfect barcoding gene; how much can you rely on plastic morphology for identification?
  • Underrepresentation of octocorals (and other oversimplified reef components like sponges) in traditional reef survey methods.
  • Associated species diversity, with particular focus on the flamingo-tongue snail and its host preference.
  • How disease, such as Aspergillosis, affects population dynamics in the environment.

My fieldwork is most awesomely supported by Operation Wallacea. Get a glimpse into what that’s like:
