I am interested in taxonomy, paleoecology, systematic, assessment and biogeography of diatoms. My research is directed toward understanding diatom biology and the ecological roles of diatoms on the planet. I am passionate about sharing diatom taxonomy and ecology with scientists, students and the public. I currently serve as the Chair of the Editorial Review Board for collaborative, electronic, peer-reviewed flora, Diatoms of North America (diatoms.org).
