Blaszczak Watershed and Aquatic Ecosystem Ecology Lab
at the University of Nevada, Reno
Flathead Valley, Montana (Google Earth Image)
Welcome! Our group studies the transformations and transport of nutrients, carbon, and contaminants through watersheds and the ecosystem ecology of the streams that drain them.
We are a growing group of freshwater scientists at the University of Nevada, Reno. We use a combination of field (environmental sensors and surveys), lab (analytical chemistry and mesocosm experiments), and modeling (time-series models) approaches to address the questions we are most excited about!
Read more about our research here and check for opportunities to join the lab.
