Interests and Expertise

Diana Oviedo Vargas’s research seeks to improve knowledge of the elemental cycles in streams, rivers, and estuaries and how they are linked to each other, the water cycle, and the terrestrial ecosystem at the surface and the subsurface level. Some of her current research interests include the nitrogen and phosphorus transport and transformation in fluvial systems and how human activities such as agriculture and urbanization can affect these processes; the quantification and characterization of the multiple carbon pools and fluxes in aquatic ecosystems and their role in global climate change; and the effects of emerging contaminants, like pharmaceutical products and microplastics, on the health of streams and rivers. Oviedo Vargas’s expertise includes aquatic ecosystems in temperate and tropical zones and along the full river continuum — from headwaters to large rivers to estuaries and the coastal ocean.
