I am interested in the evolution and systematics of marine, freshwater
and terrestrial algae in the Hawaiian islands. Research
in
my lab involves field collections in all three of these habitat
types, as well as various techniques for morphological, anatomical
and molecular characterization of algal populations and species.
We are also interested in developing methods for characterizing
algal biodiversity. Some of the key questions we address include:
1)
How diverse is the Hawaiian seaweed flora (revealed through
both morphological and molecular characterizations)? How many
unique algal species have evolved in the Hawaiian islands in
each of the different habitats? 2) What is the
degree of endemism in each of the different algal habitats?
How can
we use molecular tools to effectively characterize various
types of algal assemblages? 3) How structured are populations
of
alien invasive seaweeds in Hawaii? What can population genetic
analyses tell us about the source and spread of invasive
seaweeds around the island chain?
