Our new report on the health impacts and economic costs of air pollution in Utah is now out. Visit the air pollution page. or click here for the PDF.

We research how human activity affects the water and nutrient cycles that sustain all life on Earth. Our current projects investigate water chemistry in river networks undergoing permafrost degradation in Alaska, nutrient pollution in agricultural and urban landscapes around the world, and interactions among people, wildfire, and water quality in the Utah Lake watershed. We also use expert assessment methods to explore how sub-sea permafrost, air pollution, wildfire, and water security respond to environmental changes.
