My primary interest is in the systematic biology (nomenclature, phylogeny, taxonomy) of golden algae (heterokont and haptophyte algae).  I am also interested in growing both freshwater and marine species in culture.  I collect algae from bogs, ponds, lakes and streams in the Keweenaw, including the open regions of Lake Superior.

Research Interests

  • Chrysophyte algae
  • Algal Systematics
  • Algal Culturing
