Education


Ph.D. Ecology (1996), Colorado State University, Fort Collins CO. Dissertation: Algal investigations at varying temporal scales in an extreme environment: McMurdo Dry Valley Lakes, Antarctica.

Professional Interests


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 the United States.
