Research Topic: Biogeography and Ecology of Seaweeds 

Using a publicly available database of seaweed occurrence records dating back as far as the 1800s, I am investigating how the composition of seaweed communities in the Gulf of Maine has changed over time. This includes comparing species diversity among several sites in the region both historically and presently, as well as trying to detect shifts in the geographic range of individual algae species. I am also interested in studying the impacts that certain recently introduced seaweed species are having on their native competitors.
