Research area:

taxonomy, systematics, evolution, biogeography, and ecology of diatoms. These organisms play important roles in aquatic ecosystems and provide us with oxygen through photosynthesis. Research focuses on freshwater diatoms, and currently there are projects on them in Colorado, China, Southeast Asia, India, Europe, South America, and Lake Baikal in Russia.
