Sarah’s research program addresses the potential to enhance aquatic ecosystems while maintaining water resource benefits for people in water scarce regions, particularly the American West. Systems analysis, mathematical modeling and field studies are methods she uses to improve understanding of systems and explore promising solutions to problems. Specific branches of her research include:

  • improving water systems by modernizing or re-operating infrastructure
  • coordinating management of water quantity and quality for aquatic ecosystems
  • modeling climate change effects on hydrology, water quality, and aquatic habitat, as well as identifying potential adaptations for water resources management in an uncertain future

Sarah received her Master’s Degree in Geography in 2003 and PhD in Geography in 2008, both from University of California, Davis. Prior to coming to USU, she worked as a postdoctoral scholar at UC Davis' Center for Watershed Sciences.
