research overview
- My research focuses on the taxonomy, systematics, evolution, biogeography and ecology of diatoms. These organisms play important roles in aquatic ecosystems, and provide us with oxygen through photosynthesis. Despite the important roles they play, we still know very little about their diversity, biogeography and ecology. I have focused my research on freshwater diatoms, and currently have projects on them in Colorado, China, Southeast Asia, India, Europe, and South America. I study both living and fossil species of diatoms, and ask questions about their evolution, systematics and taxonomy as well as practical applications of these fascinating organisms.. A newly-funded project explores a lineage of diatoms that form a symbiosis with Blue-Green Algae.
