Research Interests
Algal Biodiversity – diversity, phylogeography, systematics, evolution and ecology of the marine, freshwater and terrestrial algal 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 algal lineages in the Hawaiian islands , their mechanisms of spread, and their evolution and subsequent phylogenetic relationships.
