Research Topic: Interactions between a native herbivore and an invasive seaweed

Broadly speaking, I'm interested in how introduced species eventually become normal parts of invaded ecosystems. More specifically I am studying the introduced seaweed Codium fragile and the native herbivore Placida dendritica. By analyzing the life history of the herbivore and the phenology of both species I hope to understand how the two interact and if that interaction is complimentary or antagonistic. I am also interested in the use of online databases and historical information to explore the impacts of introduced species. There is a wealth of freely accessible data that can be used to answer ecological questions, but it requires new techniques and new ways of thinking.
