Research Interests

I’m a post-doctoral research associate studying marine science at the Virginia Institute of Marine Science, The College of William & Mary in Gloucester Point, VA.

My interests span from marine community ecology with a focus on seagrass systems, to biodiversity science, to ecological statistics. My research focuses on new ways of thinking about biodiversity, specifically the use of organismal ‘functional’ traits and evolutionary history to help answer ecological questions using a combined experimental and observational approach.

In particular, I’m interested in how functional traits, and phylogeny and taxonomy, can be used to describe and explain patterns and processes in nature. I’m currently:

  • Investigating how the structure and diversity of animal communities respond to the continued restoration of a foundational eelgrass species using data from the VIMS SAV Restoration program.
  • Exploring global biogeographic patterns, mechanisms of community assembly, and drivers of productivity in reef fishes using data from the Reef Life Survey network.
  • Investigating seasonal and interannual patterns in invertebrate diversity in Chesapeake Bay seagrass beds, with an emphasis on community responses to catastrophic warming events.
  • Explaining how seagrass/macroalgal beds function, using experimental manipulations of estuarine consumers and conducting a literature review of faunal-macrophyte interactions.
