Shirley’s research addresses knowledge gaps that limit our understanding of cultured clams and natural or restored oyster reefs in Florida’s coastal and estuarine ecosystems. She examines the effects of water quality on shellfish productivity, the physiological mechanisms that underlie those effects, the provision of ecosystem services by shellfish, and the development of models to predict impacts of water quality parameters on shellfish productivity and provision of ecosystem services.

Shirley’s extension goal is to provide leadership and support to the shellfish industry, agriculture industry, and citizens of Florida in the areas of aquaculture and molluscan invasions. She engages with county and statewide faculty to identify emerging industry needs, collaboratively conducts appropriate research, and delivers sustainable solutions to clientele.
