The overall focus of research in my laboratory is toxic or
harmful algae - the species responsible for the phenomena commonly called
"red tides" (for more details, see www.whoi.edu/redtide/labweb/). Our work
spans the spectrum from mesoscale investigations of algal bloom dynamics
to studies at the cellular and molecular levels. The "system" we work with
the most is the toxic dinoflagellate Alexandrium, the genus responsible for
poisonous red tides in many countries throughout the world. Alexandrium is
perhaps the most important of all toxic dinoflagellates, and serves as an
excellent model for many other red tide species. General project topics include:
Biogeography and population genetics of harmful algal blooms
Mating interactions and mating incompatibility in Alexandrium dinoflagellates
Distribution of the toxic diatom Pseudo-nitzschia in the northeastern
U.S.
Development of molecular probes for the enumeration of harmful algal
species
Nutrient and toxin physiology of toxic dinoflagellates
Mitigation strategies for suppressing harmful algal blooms
Dinoflagellate cyst dynamics
Molecular probe-based detection of harmful algal bloom species
