Algal Biodiversity - diversity, phylogeography, systematics, evolution and ecology of the marine, freshwater and terrestrial algae floras of the Hawaiian islands

Statement
The Hawaiian islands are a unique location for the study of biodiversity, adaptive radiation and island biogeography. Research in my lab is concentrated on the systematics of various photosynthetic protistan lineages in the Hawaiian islands , their mechanisms of spread, and their evolution and subsequent phylogenetic relationships. We are actively investigating the systematics and biogeography of several widely variant groups: the fleshy crustose red seaweeds (marine), invasive seaweeds (marine), stream macroalgae (freshwater) and the trentepohlialean green algae (subaerial).
