Dr. Marina Potapova Marina Potapova joined the Diatom Herbarium in January, 2008. She studies taxonomy, ecology, and biogeography of freshwater diatoms. She has extensive experience in using diatoms for water quality assessment and through that experience she came to appreciate the magnitude of the problems in diatom taxonomy. Dr. Potapova is interested in understanding the patterns of speciation in diatoms, and developing tools for their reliable identification. Her short-term goals include cataloguing diversity of the freshwater diatoms of the continental United States, developing ways of quantifying morphological characters of diatom frustule based on geometric morphometrics, and studying taxonomy and systematics of monoraphid freshwater diatoms.
