The primary goal of my research is to understand how habitat forming species influence the structure and function of marine ecosystems. Interspecific interactions are a key pathway through which habitat forming species influence the structure and function of ecosystems. The outcome of interspecific interactions is not static and is influenced by many things including the abiotic context and spatial configuration of the species. Anthropogenic activities are causing rapid and widespread change in both spatial configuration (habitat destruction) and abiotic conditions (nutrient loading, climate change) oF marine environments. Therefore a secondary goal of my research is to understand the effects of environmental change on the impact of habitat forming species on the structure and function of ecosystems.. Under this broad umbrella my research addresses several specific questions, including:

  • How do species interactions shift over a gradient of abiotic conditions? 
  • Do natural gradients in abiotic conditions affect species interactions differently than man-made gradients? 
  • What are the consequences of shifts in species interactions for ecosystem structure and function?
  • How does the spatial distribution of habitat forming species influence their impact on the structure and function of ecosystems?
  • Can landscape metrics be used to monitor the recovery of habitat forming species?
  • How have anthropogenic impacts, such as eutrophication and climate change, altered nutrient processing in sponges and what are the consequences for ecosystem function?
  • How do species aggregations impact the structure and function of the ecosystems which host the aggregation?
  • What is the role of filter feeding organisms in controlling productivity and nutrient cycling in marine ecosystems?
  • Are consumer driven biogeochemical hot moments relevant to ecosystem structure and function over long time spans?

After graduating from high school in Missouri I left the midwest to attend the University of Georgia. In 2004 I graduated with a BS in Ecology and a new love of Georgia football. After working for the US Forest Service and Forfar International Field Station I returned to school. In 2009 I received my MS in Ecology from Utah State University where I studied the antipredator behavior and learning capability of an endangered fish, the June Sucker, Chasmistes liorus liorus. 

I recently completed my PhD at North Carolina State University where I worked in the Layman Lab studying how sponges alter community composition and ecosystem function in tropical and subtropical nearshore marine ecosystems. I am now an NSERC Visiting Fellow with Fisheries and Oceans Canada where I am studying species interactions and ecosystem function of Glass Sponge Reefs.
